Competitor features and pricing change often — this reflects our understanding at the time of writing. Check Strong's official site for the latest.
The differences that matter most if you want more than a plain logger.
An AI training partner built into the app: instant written summaries after every session, and AI that finds or builds workouts and exercises from a plain-English description.
Automatic progression that raises your weights or reps based on your real logged results, using only the equipment you own.
Sign in to Joti from Claude, ChatGPT or other AI assistants and let them pull your stats, build or duplicate workouts, and manage your calendar in plain conversation — every AI change is logged and one-tap undoable.
A body progress photo comparison tool with both side-by-side and wipe-slider views, plus weight and body fat synced straight to Apple Health / Health Connect.
Points, streaks and ranks to keep training a habit — plus 75+ themes and a customisable dashboard.
Guided Rounds for boxing, kickboxing, Muay Thai and other round-based training, with built-in round and rest timers.
Very competitively priced — and the AI training partner is included, not a separate paid add-on.
Strong is long-established, very polished and deliberately minimalist. If you want a battle-tested, no-frills logger and have no interest in AI features or gamification, Strong is a great choice.
Both handle the core logging — sets, reps, weight, rest timers, warmup/drop/failure sets, supersets and personal bests — well. Joti adds an AI training partner (written session summaries, AI workout and exercise search), automatic progression, and lets you connect Claude or ChatGPT directly to your training data, plus points and streaks. Strong is a simpler, long-established, minimalist logger. Choose Joti if you want AI feedback and progression; choose Strong if you prefer a no-frills tracker.
Strong is a traditional strength-training logger and does not offer AI-written session summaries, AI workout generation, or a way to connect an AI assistant like Claude or ChatGPT to your data. Joti builds all of that in.
Joti is free to download and free for your first month, no purchase required. After that, an optional subscription unlocks everything — current pricing is shown in the app and on your app store.
