Kaizer vs Hevy Coach
Hevy Coach connects trainers with the Hevy app; Kaizer adds routine generation and adaptation, business management and Spanish support. Neither offers a per-coach white-label app.
Hevy Coach prioritizes manual programming and an experience connected to the Hevy app. Kaizer adds routine generation and load adaptation after each logged session, while the coach keeps the final decision. Kaizer clients train in the Kaizer app, not a white-label app.

Where Hevy Coach is still reasonable.
If your clients already use the Hevy app individually and you want minimal friction to layer coaching on top, Hevy Coach is direct. The integration with the main Hevy app is nice. For coaches with fewer than 10 clients who only need to program and see progress, it can be enough. For everything else, Kaizer.

FAQ: Kaizer vs Hevy Coach.
No. Hevy Coach is manual: the coach updates the plan by hand whenever they decide to change it. Kaizer automatically adjusts weights and reps after every workout the client logs, recalculating the estimated 1RM with NSCA tables using sets, reps and RIR. The coach switches it on or off per client, and any week they edit drops out of the calculation permanently.
No. Your clients use the Hevy app under the Hevy brand. With Kaizer they use the Kaizer app, where they see their trainer, routines and tracking; Kaizer also does not offer a per-coach white-label app.
Kaizer focuses on personal trainers and individual programming; it does not publish gym-operations features.
Hevy Coach's official page showed USD $25/month when this comparison was reviewed. Kaizer has a Free plan up to 3 clients and paid plans from USD $19/month. Check the sources and current pricing before deciding.
