GymGrid Pro is now completely free. This app — "GymGrid Lite" — is the simplest habit-only version. The much more capable GymGrid Pro is now free too, so we recommend it. ▸ Search "GymGrid Pro" on the App Store ▸ Or: https://apps.apple.com/app/gymgrid-workout-tracker/id6768222847 — Lite vs Pro — Lite: Tap-to-mark-done habit logging Pro: Detailed weight & reps logs / progress charts / home-screen widget / save & share as image / calorie estimation / pocket lock Lite remains useful if all you need is habit tracking, but with Pro now free, we recommend Pro.
