Delta: Workout Tracker Gym Log

AI Trainer, Strength & Planner

Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.

Delta turns progressive overload into a system you can actually follow. Log your sets in seconds, beat your last session, and watch your strength climb — workout after workout. Most lifters stall because they train on feel.

A rebuilt start. New onboarding. Delta reads your goal, your level and your body before it writes a single session — now in 35 languages. Goal bodies in Evolve. Choose the physique you're training toward from six ready-made targets, or use your own photo. Transformation share card. Week 0 and week 16, side by side. Faster launch and smoother widgets. Images no longer hang on slow connections, exercise names are clean, and new accounts no longer start with placeholder goals.
