Sensei AI
A coach who actually read your data.
Sensei is powered by Anthropic's Claude. It knows your last 30 sessions, your active training camp, your fight week if you're in one, your daily readiness, your skill tree progression, and your PRs.
It doesn't hallucinate a generic Z2 run. It says: "Your last two sessions hit sRPE 8+, sleep is 6% below baseline, ACWR jumped to 1.4. Tomorrow you should run Z2 35 min, skip resistance, and add an extra mobility block before bed." That's a Sensei response, grounded in your training history.
What Sensei can do: chat with full context, log voice workouts, debrief sparring sessions, build daily plans, scout opponents, simulate drill situations.
Sensei is Elite-tier ($19.99/mo or $149.99/yr). Conversations are processed by Anthropic: full disclosure in the privacy policy.
Voice logging
Speak your workout. Watch it log itself.
Combat and endurance sessions log themselves from voice. "Three rounds rolling, got a triangle, sRPE seven" becomes a fully-structured combat session in 8 seconds.
Speech is transcribed on-device by Apple's Speech framework. The transcript (not the audio) is sent to Claude to extract discipline, rounds, technique attempts, intensity, and free-form notes. You review and save.
Resistance voice parsing is the most-requested v1.1 feature, shipping inside the first 30 days of launch.
Skill tree
14 disciplines mapped to your progression.
BJJ, MMA, Muay Thai, boxing, wrestling, karate, judo, sambo, kickboxing, taekwondo, krav maga, capoeira, kali, lethwei. Each discipline has a tree of techniques: strikes, takedowns, submissions, escapes, position transitions.
Log a sparring session and tag the techniques you drilled or hit. The tree fills in over time. See exactly where your training is concentrated and where you've gone weeks without touching a position.
The strength side gets the same treatment via exercise library + PR tracking per movement.
Daily readiness
One number. Every morning.
Versus reads HRV, sleep, RHR, training load, and the prior 7 days from HealthKit. It compares against your 30-day rolling baseline and outputs a readiness score from 0 to 100.
The score isn't a vanity stat. Sensei uses it to decide what to recommend, Training Camp uses it to adjust the next block, Fight Week uses it to flag overreaching during the cut. You see it once each morning; the rest of the app silently uses it everywhere.
Free tier. Every user, every day.
Training calendar
Your whole training year, on one page.
Month view or week view. Each day is a square; each session is a dot. Combat sessions are red, resistance is orange, endurance is blue, sport is purple, mobility is teal. Glance at a month and see whether you've been balanced or you've drifted toward one mode for three weeks straight.
Top of the page shows monthly totals (sessions, hours, current streak) and a stacked bar of where the hours went. Tap any day to drill into what you logged.
Free tier. Available the moment you finish your first session.
Training Camp
Periodisation that adapts to your readiness.
Set a goal date (fight, race, peak block) and a primary modality. Versus generates a 6-week periodisation with build, peak, and deload phases. Targets per modality per week: strength volume, combat sparring load, endurance HR time-in-zone.
As you train, the camp adapts. Two readiness scores under 60? Suggested deload moves earlier. Two PRs hit faster than projected? The peak block recalibrates.
Core tier.
AI Daily Stack
Sessions planned and prescribed each morning.
Every morning Versus assembles a session plan for the day. Modality, target intensity, target duration, target zones if endurance, target rounds if combat, target volume and movements if resistance. Grounded in your readiness score, your active Training Camp phase, your last 7 days of load, and your scheduled events (game, race, fight) if any.
Skip a recommended session and the next morning's stack adjusts. The plan is opinionated but never rigid.
Core tier.
AI Mobility Protocol
Post-session mobility, prescribed by AI.
Finish a session and Versus generates a mobility block tuned to what you just trained. Sparring six hard rounds? You get neck, hip, shoulder work weighted toward the positions you spent time in. Heavy lower-body day? Hip flexors, glutes, hamstrings, ankle work in priority order.
Movements pulled from the mobility library, prescribed in 8–12 minute blocks you can actually execute before bed.
Core tier.
Fight Week
Weight cut, hydration, weigh-in countdown.
Enter your fight date and target weight. Versus builds a daily plan for the week: water intake curve, sodium curve, sauna sessions, training taper, and the morning-of weigh-in protocol.
Log water and sauna time as you go. Sensei flags if your cut is on or off pace. The night before weigh-in, the protocol switches into the dehydration phase.
Core tier. Combat-discipline athletes only.
Vanity Vault
Body composition tracking that respects your privacy.
12 measurements: weight, chest, waist, hips, arms (R + L), thighs (R + L), calves (R + L), neck. Log every 2-4 weeks. See trend lines, not snapshots.
Optional progress photos stored privately. Elite-tier AI body-fat estimate analyzes the photo to return an estimated body-fat percentage, opt-in only.
3 check-ins free, unlimited on Core.
Gym Feed
Accountability with a small group, not a public feed.
Join a gym with a code (or create one). Members see opt-in workout posts from each other: sessions, PRs, captions, optional photo. Reactions, comments, leaderboards. Block + report controls on every post.
Sharing to feed is off by default. You opt in per workout. Your gym never sees your training unless you say so.
Free tier.
Imports
Five years of history in one tap.
Strava, Hevy, Strong, Fitbod, Garmin. Import your full history as part of onboarding, or anytime from Settings. Your PRs travel with you. Your ACWR baseline starts from real data, not zero.
Free tier: we don't gate switching costs.
Apple Watch
Native watchOS app, not a phone-screen mirror.
Combat round timer with rest intervals, sRPE prompt at session end, live HR throughout. Endurance lap splits + interval prompts. Sessions sync back to the phone via WatchConnectivity before you tap out.
Works standalone. Start a session from the watch without the phone nearby, sync when it reconnects.
Free tier.
