STRENGTH RANK Every lift you log is scored against published strength standards for your bodyweight and sex, muscle by muscle, from Iron to Diamond. See a body map of where you're strong and where you're lagging, the exact weight that moves you up a tier, and a button that builds a program around your weak point. Other apps charge for this. WORKOUTS BUILT AROUND TODAY Tell Form your energy, soreness, equipment and time — or just type what you want in plain English.

Verdict
The clearest difference is rating: Form at 5.0 against Chrono PullUps's 4.0. Form also leads on in-app purchases (none vs 1) and ratings volume (3 vs 1). Chrono PullUps's advantage is update cadence (weekly vs every 3 weeks) and iOS requirement (9.0 vs 15). On price, review sentiment, ads and device support there is nothing between them.
