Fitness apps proliferate. Most are feature-rich, distracting, and underdeliver on the core need: tracking workouts and progression. Simpler tools (paper notebook, basic spreadsheet, minimal app like Strong) usually outperform feature-rich alternatives.
What you actually need to track
Exercise, weight, reps, sets. Date. Brief subjective note (energy, sleep). That's it. 30 seconds per exercise.
What feature-rich apps add (and why it's mostly noise)
Heart rate, calorie burn estimates (often inaccurate), social sharing, achievement badges, complex programming. Most of these create distraction without improving outcomes. Some users get caught optimising tracking instead of training.
Simpler is usually better. Strong, Hevy, FitNotes — minimal apps that do one thing well. Or a paper notebook. Save the feature-rich apps for when basics are mastered.
