A program, not just workouts. Anyone can hand you a workout. A workout makes you sweat. A program makes you stronger — every session structured, sequenced, and building toward your goal. On Program is an AI coach that builds a real training program around you: your goals, your experience, your schedule, your equipment. Then it guides you through every session, logs your work, and keeps the whole thing moving forward — week after week, without gimmicks, without guesswork. How it works: Tell it who you are and what you're working toward. It builds your program — not a template with your name on it, an actual program designed around your life. Then you just show up. It tells you what to do, you do it, it logs it. Every session counts toward something. What you get: A personalized program built around your goals, schedule, and equipment Guided sessions — every exercise, set, and rest period laid out Complete training history — every rep logged, nothing lost A coach you can talk to, before, during, or after training Structure that respects your real life — schedule conflicts, standing commitments, poor recovery, all of it Who it's for: People who are done winging it. Whether you're picking up a barbell for the first time or you've trained for years and stalled out, the answer is the same: a real program, followed consistently. The progress takes care of itself. No muscle confusion. No random sweat sessions. No wondering if any of this is adding up. Just proper training, done right.

Verdict

The call

The clearest difference is in-app purchases: On Program App at none against Sonar's 7. On Program App also leads on rating (5.0 vs 4.6). Sonar's advantage is ratings volume (336 vs 2) and update cadence (weekly vs fortnightly). On price, ads, device support and iOS requirement there is nothing between them.
