New app: liftmath

F-Droid has workout logs like Flexify. liftmath is the calculator you use between sets, not a log. It takes the median of six published one-rep-max formulas and adjusts for RPE or reps in reserve, works out plates for the plates you actually own with a warm-up ramp, and places your DOTS score against every lifter in the OpenPowerlifting database. All of it works offline, with no INTERNET permission.

Required

• The app complies with the inclusion criteria
• The original app author has been notified (and does not oppose the inclusion) (I'm the author)
• All related fdroiddata and RFP issues have been referenced in this merge request (there aren't any)
• Builds with fdroid build and all pipelines pass
• There is an issue tracker and contact info of the author so that we can report bugs and contact the author.

Strongly Recommended

• The upstream app source code repo contains the app metadata (summary/description/images/changelog/etc) in a Fastlane or Triple-T folder structure
• Releases are tagged and auto update is enabled

Suggested

• External repos are added as git submodules instead of srclibs (there are none)
• Enable Reproducible Builds
• Multiple apks for native code (no native code)

---

liftmath is a gym calculator: 1RM estimates, plate loading with warm-up sets, Wilks/DOTS/IPF GL, a records lookup and a rest timer. The Android app is the project's own web app bundled as local assets and served through WebViewAssetLoader, so it has no INTERNET permission. The only dependencies are androidx.core, androidx.activity and androidx.webkit.

The v2.5.0 APK on the release page is signed with apksigner 34.0.0 (v2 and v3 only), and apksigcopier copies that signature onto a clean unsigned build of the tag without complaint on my machine.
