Health Connect

Your values for every app you allow.

  • You choose the data typesGesynd reads and writes only the data types you allow.
  • Rewrite everythingOne tap, and the app writes all values again with the next sync.

Backup

Encrypted backups. Readable only with your code.

Gesynd encrypts every backup with a key only you have. You get it as a recovery code of 56 characters. Without this code nobody can open the file, not even us.

  • Recovery codeWrite it down and keep it apart from your phone.
  • New phoneBackup and code are all it takes to bring everything back.

Analyse on your computer

For depth, your data on your computer.

A phone lacks the room to overlay values, compare several at once or spot correlations. So Gesynd exports all your data in the Apple Health export format. You open the file on your computer in KIWI Health, software for analyses and reports.

  • Everything in one fileAll values in the Apple Health format, workout routes as GPX, ECGs as CSV.
  • Analyses and reportsKIWI Health turns them into analyses and reports you can take to your doctor.
  • Windows and MacKIWI Health runs on Windows 10 and 11, and on a Mac in a virtual machine with Windows 10 or 11.
