Everything StallFix can do
From a lightning-fast logger to an AI coach that spots your stalls and plans your training and nutrition. Here's the full picture.
Train & log
Fast workout logging
Add exercises, log sets, reps, weight and rest. Tonnage and session duration are tracked automatically. Works fully offline.
Hands-free voice logging
Mid-set, just say it — "80 kilos, 8 reps, RPE 8" — and StallFix fills the weight, reps and effort for you, in your language.
Supersets & circuits
Link exercises into supersets or circuits with a tap, so your logging matches how you actually train.
RPE with auto-regulation
Record how hard each set felt. If an early set is brutal, StallFix instantly suggests trimming the load on the rest — smart auto-regulation, on the spot.
Rest timer
A built-in rest timer keeps your pace honest between sets, with quick skip, next-set cues and a lock-screen notification.
Templates, programs & custom exercises
Save any session as a template, load a ready-made multi-day program, or build your own program and exercises from scratch.
Track your progress
Stall Radar
StallFix analyses your history and flags exactly which lifts are progressing, slowing or stuck — so plateaus never sneak up on you. Free to see.
Analytics & recovery map
Weekly tonnage trends, per-muscle-group breakdowns and a muscle-recovery heatmap that shows which areas are fresh and which need rest.
Records & estimated 1RM
Automatic personal records and estimated one-rep-max so you always know your true strength — including quiet "hidden wins".
Body weight & measurements
Track body weight and height with trend charts for free. Pro adds detailed body measurements — waist, chest, arms and custom sites like forearm or neck.
Apple Health sync
On iPhone, import last night's sleep and your latest HRV from Apple Health so the AI's readiness score reflects how recovered you really are.
Streaks & milestones
Weekly streaks keep you accountable and reward consistency — the real driver of results.
AI that actually coaches
Post-workout AI plan
After each session, the AI scores your readiness from your training and sleep, then recommends the weights, sets and focus for next time.
AI coach chat
A conversational coach that answers questions about training, recovery and nutrition using your actual history for context.
AI anti-stall protocol
For any stalled lift, the AI diagnoses the likely cause and gives you a precise week-by-week protocol to break through — plus a retest target to confirm it worked.
Physique photo analysis
Upload a clear front and/or back photo. The AI identifies lagging muscle groups and what to prioritise — and refuses anything that isn't a proper physique photo. From the result, build a corrective mesocycle in one tap.
Before/after photo AI
Keep progress photos private on your device and let the AI compare two shots, calling out visible progress and what to keep working on.
AI mesocycle planner
Generate a complete multi-week block with accumulation, intensification and deload phases. Choose weeks, frequency, split and focus — or describe exactly what you want in plain words and let the AI build it.
Digital Twin
A living projection of your strength. StallFix models where each main lift is heading over the coming weeks and shows how today's training bends the curve up.
Weekly nutrition plans
A 7-day plan with daily calories, macros and meals — each with foods and alternatives — built around your goal, height, weight and dietary preferences. Save it, and generate a ready-made grocery list in a tap.
Made to feel right
Six languages
Italian, English, Spanish, French, German and Portuguese — including AI responses, switched from a single tap.
Your units
Switch weight between kg and lbs, height between cm and in, and nutrition between grams and oz. Stored consistently, shown your way.
Light, dark or system
Choose a light or dark theme, or let StallFix follow your device automatically.
Cycle-aware training
Optional menstrual-cycle sync lets the AI factor your current phase into its recommendations — private and fully on-device.
Privacy-first
Your data lives on your device and, when signed in, syncs over a secure backend with row-level security. Photos and voice are analysed, never stored on our servers.
Cloud sync & guest mode
Try everything as a guest with no account, then sign in to back up and sync across devices whenever you like.
