BellSense: Kettlebell Coach

BellSense is your coach. Tell it your goal and the days you can train, and it calls every session — what to do, how heavy, how hard. Each one moves on what you actually did. Make every rep matter. How the coaching works Pick a program, or just ask what to train today. Each session tells you what to do. You log your sets and rate how they felt, and the coach reads all of it — reps, effort, volume, heart rate if you wear a monitor, and your sleep, HRV and resting heart rate from Apple Health, combined into a daily readiness score. Then it makes the call a coach makes: add weight, hold, or back off. Decided by your results and your recovery, not by a calendar — and it tells you why it chose what it chose. The programs Beginner foundations through advanced work: strength, hypertrophy, power, density, conditioning, and skill. Four weeks to several months, two to five days a week. Kettlebell on its own, or paired with a barbell or bodyweight. Filter by your level, your days, and what you are training for. Finish one and the coach runs your first session again as a retest, so you see what changed in your own numbers. Every program is free. Four ways to track a set • Prop your phone up and the camera counts your reps as you go — squats, presses, rows, swings, snatches • Log it by hand in a few taps • Film a set and get it read back rep by rep • Cardio — run, row, bike, ski, swim, sled, or anything else — logged, or read live in heart rate zones Complexes Chain lifts into one set — clean to press to squat, without setting the bell down. Timed rounds, and you log each movement after. What it learns Every session ends with the call for next time: add weight, hold, or back off. Progress builds week over week: volume, trends, readiness, conditioning load, and whether your lifts are moving. All of it free. The coach's written read of a session is the BellSense+ layer, with a free taste first. Train with people Make a group, share your sessions, and compare on a leaderboard. Free, and entirely optional. The bell sensor BellSense started as a small sensor that mounts on the kettlebell. It is in development and not for sale yet. The app never requires one. BellSense+ An optional subscription. Your coach reads each session and tells you what the numbers mean, with weekly and monthly reviews and an on-demand read of your last 30 sessions. It rebuilds today's session when your readiness calls for it, from 30 sessions of history instead of 10. Tell it you slept badly, something hurts, or you only have twenty minutes, and it adapts the day around that. It sets a weekly conditioning target from the training load you actually carried, and it analyses unlimited lifting videos, scoring how your form held across the set. Programs, progression, and cardio stay free. • BellSense+ Monthly — $9.99 per month • BellSense+ Annual — $79.99 per year BellSense+ Live The top tier.
