All of it in one place, without leaning on three other apps. NO TRAINER YET? Browse the marketplace inside the app. Every profile shows how that coach works, their specialties and whether they train online, in person or both. Subscribe to the one that fits and they are notified the moment you join. YOUR SESSIONS, IN DETAIL Sets, reps, load, rest. Supersets, circuits and dropsets when your plan calls for them. Every exercise ships with an illustration of the muscle it works, so you know what you are aiming at before you lift. ASSISTED PROGRESSION Week over week, Kaizer writes the loads of your upcoming sessions from what you actually lifted. You always know what to do when you walk into the gym, and the weight on the bar keeps moving. SMART REPLACE Machine taken? A movement you cannot do today?

Verdict
The clearest difference is in-app purchases: Fisic at none against Kaizer's 11. Fisic also leads on ratings volume (60 vs 9). Kaizer's advantage is update cadence (every 10 days vs every 3 months). On price, rating, ads and device support there is nothing between them.

On the App Store both sit at effectively the same score — 4.9 for Fisic against 5.0 for Kaizer. That said, the two scores are not equally well evidenced: Fisic has 60 ratings behind it against 9, so its average is the more settled of the two.
Fisic ships an update every 3 months, Kaizer every 10 days. The most recent releases landed on September 21, 2026 and September 18, 2026 respectively.
