Most fitness apps want you to log sets, reps, calories, heart rate, and goals before you have even laced your shoes. Simplest Workout Tracker does not. Tap, note what you did, done. The newest update adds an edit screen, multi-exercise days, and smart suggestions based on what you usually do each weekday. No dashboard. Just a calm calendar where streaks build up quietly. Made by one developer in Norway who needed exactly this and nothing more.
