Kaizer
The best FitBudd alternative for coaches who want AI that actually re-progresses the routine, Spanish that works great and local billing in pesos.
Pros
- Doesn't just generate: re-progresses the routine automatically after every logged session, recalculating estimated 1RM (NSCA tables) and adjusting weight and reps.
- Full Spanish that works great across the whole platform, not just a translated app.
- Shown in USD, charged in pesos — no friction of a USD-only vendor.
- Free plan forever (up to 3 clients), no card.
- Proven retention: -50% churn, 10,000+ trainers, +120,000 routines.
- Native LATAM-hours support from Buenos Aires.
Cons
- No own white-label app on both stores (FitBudd has one, on Super Pro).
- No nutrition — training-only focus (FitBudd includes meal plans).
- Younger product (launched 2024).
