Valen – Train Smarter

Valen knows what your body is actually going through right now.
You did bench, OHP, and dips on Monday. Your chest is toast, your front delts are cooked, and your triceps need a breather — but your legs and back are completely fresh. Other apps have no idea. Valen does.
Every time you finish a session, Valen maps the stress across every muscle group and tracks how each one recovers, hour by hour, in real time. You get a live front-and-back body heatmap — green means go, red means rest — that updates automatically as your body recovers. Open the app and know exactly where you're at before you even step in the gym.
No more accidentally hitting chest two days too early. No more wondering if today should be push or pull. No more junk volume on muscles that haven't recovered.
─── THE HEATMAP ───
Your body, colour-coded by recovery state. Nine levels from fully fresh to cooked — covering chest, back, shoulders, arms, legs, and core, right down to subzones like quads vs hamstrings, lats vs upper back, or anterior vs posterior delts. Tap any muscle to see exactly how fatigued it is and when it'll be ready to train again.
─── ACTUALLY SMART RECOVERY SCIENCE ───
Valen runs on the Stimulus-Recovery-Adaptation model — real exercise science, not arbitrary rest timers. Fatigue decays using per-muscle exponential curves that account for how hard you worked (RPE), what exercises you did, how heavy you went, and your experience level. Beginner, intermediate, and advanced athletes all recover at different rates. Valen knows the difference.
It also tracks MEV, MAV, and MRV — your Minimum Effective, Maximum Adaptive, and Maximum Recoverable Volume — per muscle group, per week. You'll know when you're not doing enough, when you're in the sweet spot, and when you're heading toward overtraining.
─── YOUR DAILY GAME PLAN ───
Every morning, Valen tells you which muscles are most ready to train. One glance and you know if today should be push, pull, legs, or full-body. Zero mental effort required.
─── LOGGING THAT DOESN'T SLOW YOU DOWN ───
Sets, reps, weight, and RPE. Rest timer with push notifications when your rest is up. Plate calculator that shows you exactly what to load on each side of the bar. Autosaved drafts so a dead battery never loses your session. Works with barbell, dumbbell, bodyweight, weighted, and assisted movements — all tracked correctly.
─── WEEKLY ADAPTIVE PLANNER [PRO] ───
Valen builds your training week around your actual recovery state — not a fixed template. If your back is more fatigued than expected midweek, it adjusts. Rest days and light days get flagged automatically so you never grind a muscle that isn't ready.
─── DEEP MUSCLE INSIGHTS [PRO] ───
Drill into any muscle group: subzone breakdown, 48-hour recovery forecast, 7-day training load trend, and your estimated 1RM history per exercise. Spot imbalances — like overdeveloped front delts vs underdeveloped rear delts — before they become injuries.
─── ANDROID HOME SCREEN WIDGETS [PRO] ───
See your muscle heatmap and today's top training suggestion right from your home screen, without opening the app.
─── FREE VS PRO ───
Free: full-body heatmap, real-time recovery tracking, workout logging, daily training suggestions, rest timer, plate calculator, and 30-day training history.
Pro: adaptive weekly planner, deep muscle insights, unlimited training history, cloud backup (Android), and home screen widgets.
─── YOUR DATA, YOUR DEVICE ───
Valen is fully offline. Your training data stays on your phone — not a server. No account needed to get started. Cloud backup available on Android for Pro users who want it.
Setup takes two minutes. Pick your experience level, your split, and how many days a week you train. Valen handles everything else.
Train with your body. Not against it.
