Free edition

There are two ways to get Enhanced Training Studio:

• Free edition, on GitHub: your protocol: injections, orals and supplements. Schedules and cycles, reminders, dose logging with the syringe draw, site rotation, vial stock with reorder and cost tracking, the daily check-in, estimated levels, the doctor report, backups and app lock. Current free version: 1.0.7.
• Licence, from this website: everything in the free edition, plus training (workouts, programmes, records, progression, GPS runs), blood tests (PDF import, markers over time, test planning and your own alert ranges) and health (Health Connect, readiness, weekly report, live heart rate, measurements and progress photos). Updates install with one tap inside the app, and you get email support.

The free edition is free forever. It isn't a trial: there's no time limit, no ads and no account, and protocol tracking won't move behind the licence later. Both editions get every update at the same time, including security fixes. Both keep all your data on your phone.

Installing the free edition

1. Open the GitHub page on your phone and go to Releases.
2. Download the .apk file for the newest release and open it.
3. Android asks once to allow installs from your browser. Say yes, then tap Install.

The free edition is signed with the same key as the licensed app. You can check this by comparing the signing certificate fingerprint on the download page.

Moving to a licence

Buy a licence, download the licensed app and install it over the free one. Your injections, logs and settings stay where they are. Then enter your licence key under Setup → App settings → Licence, or on the Training, Health or Labs screen.

Getting it with F-Droid

If you use F-Droid, you can get the app there and have it update like your other apps. Open the download page on your phone and tap Add to F-Droid (or add the repository address shown there under Settings → Repositories in F-Droid, and check the fingerprint matches). Then find Enhanced Training Studio in F-Droid and install it.

F-Droid gets the full app, the same one as on the download page, so there's nothing to swap later: tracking your protocol is free, and entering a licence key unlocks training, blood tests and health. It's signed with the same key as the downloads here and on GitHub, so it installs over either of them and keeps your data.

The free edition's source code is on GitHub; the licensed parts aren't open source, so the F-Droid build isn't made from that code alone.

Going back to the free edition

Install the free edition over the licensed app. Your training, blood test and health data stays on the phone, but the free edition doesn't show it. It's all there again if you move back to a licence.

The source code licence

The free edition's source code is under the Functional Source License 1.1, MIT Future License (FSL-1.1-MIT). In short:

• You can use, read, change and share the code for your own use, and for non-commercial teaching or research.
• You can't use it to offer a competing commercial product or service.
• Each version becomes available under the MIT licence two years after its release.

The full text is in the LICENSE.md file on GitHub. The name Enhanced Training Studio and its logo aren't covered by the licence.
