About

Constant

Read full description

Never wonder what to do at the gym again. Constant is an AI training coach that programs your workouts, logs your sets, and adjusts every session to how you're actually recovering. Most apps hand you a fixed plan and leave the thinking to you. Constant does the thinking: it reads your recovery, writes today's session, and adapts tomorrow based on what you logged and how you slept. The product isn't a library of workouts. It's consistency — showing up, session after session, on a plan that meets you where your body is. HOW IT WORKS Each morning, Constant checks how you recovered — from a quick Good / Okay / Bad check-in, or automatically from sleep, HRV, and resting heart rate read from Apple Health. Then it finalizes one session for the day, gated to your readiness. Train hard when you're recovered; hold back when you're not. You log each lift in seconds and mark it Easy, OK, or Hard. That feedback shapes the next session's loads. The plan is always one clear workout — never a wall of options to decode. TRAINS AROUND YOUR INJURIES Tell Constant what hurts — or record what your physio said — and every session adapts: restricted movements come out, safe substitutions go in, and loads rebuild as you recover. Most training apps ignore this entirely. WHAT YOU GET - A daily training plan that adapts to your recovery, not a fixed template - Automatic recovery readings from Apple Health: sleep, HRV, resting heart rate, steps - A simple daily check-in when you'd rather report how you feel - Fast set logging with per-lift Easy / OK / Hard feedback that drives progression - Nutrition logging with daily calorie and protein targets - AI food estimates: snap a photo of a meal, get a calorie and protein estimate - A trajectory score that tracks the one thing that matters — did you show up - Activity logging for padel and other sessions FREE AND PREMIUM The full coach is free: your adaptive daily plan, workout logging, recovery readings, nutrition targets, your trajectory score, and one AI food estimate per day. Premium ($9.99/month or $49.99/year) adds: - 10 AI food photo estimates per day - Voice recording for physiotherapy and doctor visits, with the restrictions folded into your plan The yearly plan starts with a 7-day free trial. Subscriptions are billed through your Apple ID and renew automatically unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in your App Store account settings. YOUR DATA Constant reads recovery metrics from Apple Health to adapt your training. It does not write data back to Apple Health. Meal photos are sent for a one-time estimate and are never stored. Your training, recovery, and nutrition data are tied to your account and are never used to track you across other apps. Constant supports your training. It is not a medical device and does not provide medical advice. Always consult a qualified professional for health and injury decisions. Train consistently. Let the plan adapt.
