The honest comparison.
Zenith vs Strong — workout tracker, or AI coach?
Strong has earned its place. It's a clean, fast workout logger with sensible defaults and minimal friction. If you already have a program and just want to log it, Strong is hard to beat.
Zenith is built for lifters who don't want to write their own program. The AI generates a periodised plan from your inputs, logs your sets, surfaces your PRs, and rebalances the week when life happens.
Here's the side-by-side.

FAQ
Common questions about switching from Strong
Is Zenith a Strong app alternative?
Yes — Zenith covers everything Strong does for logging sets and tracking strength, then adds a generated periodised program, nutrition, and AI physique scans. Lifters who don't want to write their own program prefer it.
Can I use Zenith as a pure tracker like Strong?
Yes. You can ignore the generated plan and log freestyle sessions. Most users keep the AI plan running because it's already tuned to their level and equipment.
Does Zenith have rest timers and plate math like Strong?
Yes. Rest timers respect your last set, and plate-math hints surface as you enter working weight.
