Tessera Fit

Every app you train with. One picture.

Hevy, Garmin, Apple Health and your watch's files, set side by side as one record of training, performance and recovery.

Founding members pay A$39 a year, locked in. We'll only email you about Tessera Fit. Privacy policy

One tile for every app you already use.

Each tile names its source and says what it brings. The coloured edge shows how it connects. Keep training with the apps you like; Tessera Fit doesn't replace them.

How to read a tile

  1. Name: the source, always visible, so nothing is anonymous.
  2. Reading: one number, as it arrived.
  3. Edge colour: how it connects.
  4. Flip: turn a tile over to see how the number was calculated.

The grout is where the work happens.

Your Hevy session and your Garmin recording describe the same hour. Tessera Fit matches them by time, removes the duplicates and joins them into one session, so nothing is counted twice.

    In mosaic-making, andamento is the flow of the rows, the lines that give a mosaic its movement. In Tessera Fit it's the shape of your training over months: every day one tile, coloured by sport, brighter when the load was higher.

    Questions

    Do I have to stop using Hevy or my watch?
    No. Keep logging the way you do now. Tessera Fit reads from the apps you already use and puts the pieces together.
    Which apps work?
    Hevy, Strong, Garmin and Apple Health, plus FIT files from COROS, Suunto, Wahoo or any other device, and your own CSV files. Polar and Withings are planned.
    Do you sell my data?
    No. We don't sell your data or use it for advertising. You can disconnect any app or delete your account at any time. The privacy policy has the detail.
    Can I see how a number was calculated?
    Yes. Every tile turns over to show its inputs, sources and formula. They stay out of the way until you want them.
    Is there an app to install?
    No. Tessera Fit runs in your browser on your phone or computer. Apple Health data comes in through an Apple Shortcut on your iPhone.
    When can I use it?
    Tessera Fit is in development in Sydney. Join the waitlist and we'll email you when it opens.

    Bring your pieces together.

    The finished picture: every tile in place.
