Kaizer vs Hevy Coach
Hevy Coach is the coach version of the Hevy fitness app (a community favorite in lifting). Kaizer is the choice if you need adaptive AI, a white-label app and local-currency billing.
Hevy Coach is the pro version of the Hevy app, popular among serious lifters. The integration with the client app is nice for end-users. But as a business tool, it's missing pieces: no adaptive AI, no white-label app, limited desktop dashboard. Kaizer covers all that, with Spanish support and prices shown in USD, charged in pesos. The AI is optional — turn it off anytime; you keep the final say.

Where Kaizer wins over Hevy Coach.
Full coach tool, not an app add-on.Hevy Coach is a layer on top of the Hevy app. It's light and elegant, but as a business tool for a coach with 30+ clients it's missing pieces: robust desktop dashboard, white-label app, adaptive AI. Kaizer is a platform designed from scratch for the coaching business.
Adaptive AI.Hevy Coach has no AI — planning is manual. Kaizer recalculates the client's estimated 1RM after every logged workout and updates the weights and reps of upcoming sessions automatically.
White-label app.Hevy Coach sends your clients to the Hevy app under the Hevy brand. Kaizer lets you ship the app under your brand.
Local-currency billing.Hevy Coach charges only in USD; Kaizer shows the price in USD and charges it in pesos.
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.

The coach can let it run unattended or use it as a suggestion.
No. Your clients use the Hevy app under the Hevy brand. Kaizer includes a white-label app from Pro.
