What is a data collection app?
You’ll hear the term “data collection platform,” “data collection tool” and “data collection app” in this space. A platform is the term for the overall software used to collect, analyze, and share data. Most data collection platforms have a companion app that allow enumerators or researchers to collect data in the field using mobile devices, like a smartphone or tablet. Some data collection apps are also standalone products.
Data collection apps or tools are applications that allow you to gather information, build forms, and create surveys to collect primary data. With these apps, you can use a variety of methods, including computer-assisted phone interviewing (CATI), in-person interviews, or self-administered surveys.
Some organizations get by with gathering data with a combination of pen and paper, Excel, and social media tools, like WhatsApp surveys. It’s not easy (or very secure, or efficient), but it works, and there are few upfront costs. But increasingly, data collection professionals and organizations are switching over to fully digital data collection processes.
Here are some of the advantages of digital data collection apps over paper forms:
- It’s more secure. Unlike a collection of paper forms, digital data collection allows you to have much more control over how data is collected, who it’s shared with, and whether it’s encrypted
- It’s easier to monitor data quality. Instead of waiting for your team to finish collecting data in the field, you can run quality checks automatically each day or each time a dataset is updated.
- It’s faster. Since data can be accessed and monitored daily, you don’t have to wait until the end of the data collection process to clean and access the data, like with pen-and-paper methods.
- Fewer errors occur. Mobile data collection systems don’t require someone to physically enter data into a system after it’s been collected, so there are fewer opportunities for errors. No data entry or survey scanning software required. And no printing!
- There are more field types options. When collecting data digitally, you can capture more information, like GPS location, photos, audio, video, or perform calculations.
- Enumerator training is easier. When you rely on enumerators to carry out pen-and-paper data collection, you depend on their knowledge of complex skip patterns, which means you have to offer lengthy training sessions. When you use an app, the software handles skip patterns, field validation, and any calculations.
As digital data collection apps grow in popularity, it’s important to know that not all apps are the same. Developing the best processes for your data collection needs means taking the time to understand which app works best for your team, your project, and your specific data collection requirements.
What is primary data collection?
In this article, we’re discussing tools that you might use for primary data collection. Primary data collection is the process of gathering data directly from a first-hand source. In other words, it’s data that’s collected by the researchers or organization that also expects to use it or share it. Methods for collecting primary data include surveys, interviews, observation, and focus groups.
By contrast, secondary data is data that’s already been collected by someone other than the primary user of the data. For example, when a researcher or students refers to existing data to write a paper on a certain topic, they are using secondary data.
Some examples of collecting primary data:
- Household surveys
- Phone interviews
- Inspections and program evaluations
To gather large amounts of primary data, you’ll likely need some kind of app or tool to organize data as it comes in, analyze it, and share it with collaborators or push it to other platforms for further analysis.
In this article, we’ll look at the top tools that can be used for collecting primary data and give recommendations for which ones are best suited to your projects.
What to consider when evaluating apps that collect data
There’s a seemingly infinite number of data collection apps available at the moment. That’s great news for you — you get to choose the data collection app that’s built specifically for your purpose, which will make your life easier. Let’s look at what to keep in mind before you start looking at specific apps for data collection.
What’s your research area?
Since data collection apps can be so specialized these days, it’s possible to find an app that specifically aligns with your research needs and specific field or industry. Monitoring and evaluation, healthcare, and education are examples of fields with data collection tools tailored to them. However, also keep in mind that tools tailored to very specific use cases may not necessarily have the same level of feature options and support available that more robust tools created for a wider audience might offer.
Think about what kind of primary data you need to collect: qualitative, quantitative, or both. All survey apps will help you gather data via a series of questions used to investigate the experience or opinions of a group of people. But the type of features you need may vary depending on the type of data you want.
If you primarily want to collect quantitative data, you should be able to use any survey application. Look for ones that let you customize form fields so you can ask for and validate specific information.
If you require qualitative data, however, you will need something more robust than a standard survey application. If you plan to do long-form interviews to gather qualitative data, you will want to find a data collection tool that is designed to handle long-form, in-depth answers and offers features specific to qualitative interviews, like video interviewing options.
When choosing your data collection app, also consider what survey mode you’ll be carrying out:
Online surveys: Do you need the ability to share a link for respondents to fill out online via a web browser?
Offline surveys: Do you need functionality that allows respondents to answer questions, even if the area you’re working in doesn’t have an Internet connection? You’ll need this if you’re collecting data in remote areas or in areas with unreliable internet connectivity.
Social media surveys: Will you be collecting data via social media?
Anonymous surveys: Do you need to protect the identity of your respondent?
High-volume surveys: Who will you be sampling? How many respondents do you want to survey? Some apps handle large amounts of data better than others, or integrate with tools that make it easy to process high volumes. There are different considerations for apps when thinking about a survey with 10,000 responses, vs. a survey with 100,000+ responses.
Are you collecting data once, or following a population over time?
Cross sectional data collection is when you sample a population at a specific point in time. Longitudinal data collection is when you sample the same population at multiple points in time. For longitudinal data collection, you need a way to collect, access, and update data as you follow entities over time. A good solution here is an entity-based data collection feature like case management which allows you to organize your data collection around cases (individual respondents, clinics, schools, or whatever else you are measuring) instead of around questionnaires.
How sensitive is your data? How much should you worry about security?
Consider how sensitive your data is. Different data collection apps have different levels of security features available, and many allow you to customize settings to keep data secure. Think about questions like:
- Who needs access to your data? Can all data be seen by all collaborators? Consider whether you want to customize permissions for different levels of access.
- Do you need to encrypt data? Encryption is a process that makes data unreadable to everyone except those who have a computer-generated key. It can be important to encrypt data when you transfer it from a device to a server to a computer and to a final storage location.
- What kinds of security requirements does your organization require? If you work for an NGO, medical facility, university or government agency, you may have strict security regulations that any data collection tool you use must comply with.
What should your budget be for a data collection app:
You’ll want to choose a data collection app that fits your current budget, but ideally the app you choose can grow and evolve with your project.
Here’s an idea of what you can expect to pay for your data collection method:
Free data collection apps: There are many data collection apps available that are free of charge. However, these apps usually provide minimal training opportunities and slower IT support than a paid app. More robust free apps will require you to have some questionnaire programming knowledge in order to use them effectively. Other free apps are easy to use, but won’t offer the feature options of a more powerful app.
Mid-range and above data collection apps: Anywhere from $25 to $250 a month for basic plans, and $500 or more per month for larger teams, advanced features, large volumes of submissions, and enterprise subscriptions
External consultants: $50,000+ per year, but they take care of data collection for you.
Consider your budget for consultants or contractors you might need to hire depending on which app you choose. For example, many open-source data collection apps are free, but in order to access the expertise required to customize it for their needs, teams end up hiring consultants.
When mobile data collection apps make the most sense
Mobile data collection apps are applications used to collect qualitative and quantitative data through a mobile application (usually a phone or tablet). Such apps are especially necessary for certain modes of data collection like computer-assisted-personal interviewing (CAPI), computer-assisted-telephone-interviewing (CATI), and computer-assisted web interviewing (CAWI). Usually enumerators, or data collectors, use a mobile device in the field to collect data as they’re administering surveys, doing phone interviews, documenting observations, or tracking items.
If your data collection projects involve data collectors traveling to meet with respondents face-to-face for interviews, using mobile devices for computer-assisted personal interviewing (CAPI) is a natural fit. Or, if you conduct phone interviews in rural, remote areas in low-to-middle income countries, a mobile data collection app designed for this purpose is the ideal solution for your needs.
Mobile data collection apps are also the data collection tool of choice if you’re working in offline settings. With the right data collection tool that offers strong offline functionality, you can collect data and even carry out a variety of advanced workflows without internet connection. Data will be stored in-app on enumerator devices, and later synced to a server when online. It’s important to note that some mobile data collection applications always require an internet connection to operate. Others (like SurveyCTO) have offline capabilities that make it possible to collect data in a standardized way in remote locations.

SurveyCTO is great for you if you’re undergoing large research or need an M&E data collection tool that works offline. You’ll love this tool if you need a data collection app that’s both easy to use and has robust functionality and fine-grained security options.
Google Forms
Google forms is the free, easy-to-use tool related to its tech giant parent. It’s great for online data collection or simple, personal surveys to a small audience. You’ll need an internet connection to use the app, since your device must be connected
Because of its history with Google Sheets (Forms used to be a part of Google Sheets), this app integrates seamlessly with Google Sheets. It is free with a Google account.
Google Forms is great for you if you have a smaller budget, you’re creating for personal or very small-scale surveys, and you love Google and don’t want a new tool/platform. Your questions are simple and straightforward, and you always have an internet connection.
SurveyMonkey
SurveyMonkey, like Google Forms, is another entry-level data collection tool. It’s easy to use, many people have had experience with it, and it actually does have quite robust features for data collection.
SurveyMonkey integrates with virtually anything, including Salesforce, Mailchimp, and Hubspot.
SurveyMonkey is great for you if you need an easy-to-use tool for large surveys (especially marketing), and your company has a budget for surveys. If you want to take advantage of A/B testing and logic, and need simple but solid built-in analytics, SurveyMonkey could work well.
CommCare
CommCare is a platform that allows organizations to build their own data collection app for frontline workers. Like SurveyCTO, CommCare is a revenue-funded product (unlike free open source tools), which means it’s able to offer some features (like HIPAA-compliant security) that other open source tools can’t.
Pricing starts at $250 per month, although sharing cases offline is only available for the $500/month tier.
CommCare is great for you if: You’re in the healthcare industry and you need a custom, HIPPA-compliant app for frontline workers.
ODK Collect
Open Data Kit (ODK) is an open-source data collection platform. Open-source tools have no licensing or subscription costs, and have a network of developers contributing to the tool. The collaborative nature of open-source tools can be beneficial, because top professionals across the field can contribute to building and improving the platform.
Since ODK is open source, there’s only forum support available, and you’ll be responsible for your own hosting and customization. This is why it’s a great tool for organizations who already have their own tech-savvy team on board, or who work with consulting firms who handle hosting and personalization.
In ODK, it’s tricky to separate between “project spaces,” i.e. separating forms and materials by team or country, unless you have an Enterprise account. This can make it difficult to work on multiple projects for multiple clients (like if you’re a survey research firm, for example). The ODK Collect app doesn’t guarantee that data is always encrypted.
Despite these concerns, ODK is great for many purposes! It’s such a solid platform that we built SurveyCTO on top of ODK, and then added in additional features, support, and security.
ODK is free, if you self-host data on your own server. ODK Cloud, which includes server hosting and support, starts at $169/mo.
ODK is great for you if you’re a social sector organization with a smaller budget for tools, and you have a tech-savvy team or you partner with a survey consulting firm.
KoboCollect by KoboToolbox
KoboCollect is the app companion to KoboToolbox, a data collection and management tool by nonprofit Kobo. It’s targeted for people working in “challenging environments” like humanitarian crises. KoboToolbox is another open source platform, like ODK. Kobo is a nonprofit, and its development is funded by partners and the community. They offer a free subscription for nonprofits, as well as additional tiers of paid nonprofit subscriptions. If you are not a nonprofit, Kobo offers multiple paid monthly subscription options. They will also provide large private servers for bigger organizations at an additional cost.
In terms of security, KoboToolbox security is GDPR compliant. Like ODK, you can choose to encrypt forms. However, it doesn’t have more fine-grained security options, such as selective encryption.
Choose KoboCollect if you have a limited budget but work in humanitarian work and need a sophisticated tool for data collection. It has similar features to SurveyCTO and ODK, but is designed for lightweight, nimble data collection during emergencies. KoboCollect is best for sophisticated, technical teams, since you’ll handle hosting on your own, and support is forum-only.
Magpi
Magpi is a for-profit mobile data collection app serving anyone, but focused on international development and healthcare. Their customers include the CDC, WHO, Unicef, and various hospitals and government organizations.
Magpi is most known for having good SMS survey capabilities, such as through WhatsApp. Pricing starts at $250 per month for their basic tier (which includes 6,000 submissions per month, unlimited users).
Choose Magpi if you’re carrying out simple surveys for cross-sectional primary data collection.
As of January 2025 Magpi is no longer offering its services. Learn more on transitioning from Magpi.
The bottom line: choose a data collection app based on your research needs
With so many apps with different strengths available, it can be daunting to select a tool for primary data collection. We’ve covered seven great choices for different types of data collection work, but there are many more options available. So how to make a final decision?
The most important thing to keep in mind: The more suited your data collection app is to your exact use case, the better (and simpler) it will make your data collection work. If you’re a researcher working on a small-scale project alone or with a small team, you might be able to get away with using a simple free tool like Google Forms. But if you do more complex work–for example, large-scale, longitudinal studies across thousands of entities in remote areas–you definitely want to look at apps built for your specific case. If you work for a survey firm conducting research for clients and do different types of data collection projects, choose an app that offers many feature options and makes it easy to collaborate with outside stakeholders. On the other hand, if you work mostly in a specific area like healthcare or agriculture, you’ll want to look for tools that have features designed with those industries in mind.
