Collect higher-quality data using SurveyCTO's powerful mobile platform – even when you're offline.

SurveyCTO is a field-tested technology platform that helps you collect data using mobile phones, tablets, or computers. Collect data online or offline, access your data as soon as it's collected, keep your data secure, and ensure data quality with our powerful quality-control features.

Access your data instantly

See your data right away. Learn – and adapt – more quickly by skipping the costly, time-consuming, and error-prone task of entering and cleaning data by hand.

Digital vs. Paper

If you haven't yet switched from paper to digital surveys, we've adapted resources from Oxfam's experience with SurveyCTO to help outline the opportunities of going digital. Read more...

How it works

SurveyCTO makes it easy to design forms, collect data, monitor incoming data for quality, and learn from that data. You can collect data online or offline, and you can use our powerful built-in tools for visualization and analysis – or the platform of your choice. Read more...

Keep your data secure

Protect your data, your subjects, and your reputation. SurveyCTO supports multiple layers of encryption and redundancy – from your device all the way to our secure servers.

Industry-leading encryption

SurveyCTO always encrypts Internet communications with Secure Sockets Layer (SSL) technology, which means your data is always secure in transit. SurveyCTO also makes it easy to encrypt all of your data at the point of collection, using your own 2048-bit encryption keys. That way, not even SurveyCTO engineers can see your data.

Cold room computer support

For your most sensitive data, SurveyCTO makes it easy to shuttle encrypted data to a cold-room computer, on which it can be safely decrypted. That way, your data is never exposed on an Internet-connected computer. (Recommended for sensitive health and financial data.)

Visualize safely

Balancing the need for uncompromising data security with the need to easily share and track key indicators, SurveyCTO allows you to control which fields to visualize or publish – and which to keep safely encrypted with your own private encryption key. With SurveyCTO, data security isn't an all-or-nothing affair.

Device-side data redundancy

SurveyCTO stores all collected survey data on the device's removable memory card and backs it up on the device's internal memory. That way, if a device fails, the data is safe on the memory card, and if a memory card fails, it is safe on the device.

Server-side data redundancy

SurveyCTO's server databases are mirrored 24x7 across multiple of Amazon's data facilities. Continuous backups are restorable to any minute of any day in the last month.

IRB compliance

SurveyCTO provides the kind of data security that satisfies even the most sophisticated and demanding institutional review boards (IRB's).

Stop worrying

You've got enough things to worry about – your technology shouldn't be one of them. SurveyCTO is best-in-class for software stability and professional support. And our user-supported business model ensures that we can keep pace with the needs of our users.

We've got you covered

Once you have built, tested, and deployed a survey, we know that it has to keep working – without fail, without change, without surprises – for its entire life (which may be years!). Here's how we make that happen:

Software stability

  • We host all SurveyCTO subscribers on fixed, stable Linux servers that we maintain ourselves. We do not use a platform like Google AppEngine that changes over time.
  • We build and maintain a separate virtual server for every subscription. Each virtual server includes the SurveyCTO server software, as well as matching versions of the Android and desktop software components. And once a Professional subscriber starts with SurveyCTO, the software for all three components is locked in and remains fixed: update to new versions only when you choose, so once you test and deploy, there are no surprises.
  • We use the same code base for our Android app and our web forms. So what you see online is what you get in the field.

Professional support

  • Access extensive online help, sample forms, and our online Support Center whenever you need help.
  • Professional subscribers can submit support requests to our knowledgeable and experienced support team.

Sustainable business model

  • We are a mission-driven company funded by – and accountable to – our users. We make decisions based on their needs, not the whims of donors or VCs. This enables us to be financially sustainable while continuously developing new features and products for our users – without any gaps in support or service.
  • We don't believe that you should require the help of consultants to use our software, so we work relentlessly to make SurveyCTO easier and more enjoyable to use.

You don't need to be a developer or to hire an expensive consultant to design a smarter survey. SurveyCTO has been built to have the features you need, a friendly user interface, and the ability to analyze your data as it streams in.
