Capazity
Read full descriptionHide full description
Capazity is strength training software for people who actually lift. Strongman, powerlifting, grip, bodybuilding, general fitness — the exercise library, the logger, the programs and the records cover them all. Every screen was designed deliberately, for the way training actually happens. — AI COACH — A coach that understands the iron. Chat with an AI that can read your program, build one from scratch, swap exercises, deload a week, or explain technique in plain language. It remembers your preferences and adapts as you grow. — PERSONAL RECORDS — PRs at every rep range, not just one. Track your best lifts across 1, 2–4, 5–7, 8–12, and 13+ reps for every exercise and every muscle group. See real strength progress at every intensity, the way serious lifters actually train. — FRIENDS & LEADERBOARDS — Train with your circle. Compete on the bar. Add friends, compare lifts side by side—who's strongest where, and who's about to add weight next week. — DIRECT MESSAGING — Chat with your friends, coaches, and clients inside the app. Talk through form cues, coordinate training, share what just happened on the platform. Comment on their shared sessions. Block and report any unwanted contact with one tap. — SHARE PROGRAMS & SESSIONS — Capazity isn't just for solo lifters. Send any template or finished session to a coach, a client, or a training partner with a single tap. They get the full program — exercises, sets, RPE, the lot — ready to run. • Coaches → Clients: Build a program once, push it to every athlete. It shows up in their app instantly — no PDFs, no spreadsheets, no WhatsApp screenshots. • Training Partners: Just hit a brutal session? Share it — every set, rep, and weight. Receipts, not bragging. • Friends & Communities: Found a template that works? Send it. They get a clean copy they can follow, edit, or remix. — LIVE SESSION LOGGING — Log reps, weight, and RPE as you lift. AMRAP, time-based, and distance-based sets supported. The session timer runs while you train. Follow the plan or run an ad-hoc session — either way, every set is logged. Volume, frequency, and intensity, at a glance. — STRONGMAN & GRIP CATALOG — Farmer's walks, yoke carries, atlas stones, axle deadlifts, rolling handles, hub lifts, blob lifts, grippers — over 200 specialized exercises you won't find anywhere else. Plus a full library across Powerlifting, Bodybuilding, Olympic Lifting, Athletic Performance, and General Fitness. — WORKS OFFLINE — Train where the signal dies. Log every set offline and Capazity syncs the moment you reconnect. No lost workouts. — MULTIPLE LANGUAGES — Full interface and exercise names in 25+ languages. The AI coach responds in your language too. — CAPAZITY PREMIUM — Optional monthly subscription unlocks: • Full personal-record statistics and longer history • Expanded friend comparisons • Premium program templates from verified coaches • 500,000 AI tokens per month (free tier: 100,000/month) Cancel anytime from your Apple ID settings. Built with the same care you bring to the bar. Train smart. Track everything. Get stronger. Terms of Use: https://capazity.ai/terms.html Privacy Policy: https://capazity.ai/privacy.html

Verdict
The clearest difference is update cadence: Capazity at every 6 days against TRTracker's every 5 weeks. Capazity also leads on iOS requirement (16.4 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
