DataFlow

DataFlow checks field survey data while the team is still in the field. It connects to SurveyLoopr, SurveyCTO (encrypted forms too), ODK Central and KoboToolbox, and imports CSV or Excel exports from any other tool. New interviews are checked the moment they sync. - Checks set up from your form: duplicates, outliers, interview duration, missing answers, don't know and refusals, logic and range rules, GPS and travel speed, back-check differences, and signs of fabricated interviews per enumerator. - One ranked list of problems, each with a fix ready. A local AI explains each flag and prepares the fix; you approve it. The AI runs on your computer, even offline. - Raw data is never changed. Every correction is logged with who, when and why, can be undone, and lands in a Stata do-file that rebuilds the clean data. - Personal data is kept in a VeraCrypt-compatible encrypted vault; downloads are de-identified by default. - Field Reports: one file your client opens in any browser, with no install or login. - Exports for Stata, R, Excel and CSV. Windows, macOS and Linux. DataFlow grew out of arceddataflow, the Stata workflow ARCED Foundation cleans its surveys with, and is in daily use there. A sample study with 600 household interviews ships inside the app; no account needed. Pricing: $19 per seat a month, or $99 a year with 5 seats included (extra seats $4.99 a month each, billed yearly). Every feature in every plan. 7 days free.
