Strength & rehab training log
Log strength and rehab work in seconds, get cautious progression advice, and keep every rep on your device — no account, no cloud, no tracking.
Your Workout, Recorded in Seconds
Grip & Balance is built around one idea: the log should get out of your way. Tap into a routine, hit your sets, and you're done. No forms to fill, no menus to navigate, no friction between you and the work.
Everything You Lift, Covered
Weight × reps, reps-only, timed holds, and rehab exercises all live in the same log. Switch between them without changing apps or workflows.
Flexible by Design
Routines hold exercise slots with quick substitutions — swap a movement on the spot without losing your place. Edit any set live during a session, or go back and correct it from history at any time.
Rest Timer
A quiet rest timer sits between sets — enough structure to pace your recovery without pulling your attention away from the next lift.
Live Editing
Made a mistake mid-session? Edit any set in real time. Come back later and correct from history. The log works on your schedule, not the other way around.
Quick Substitutions
Swap an exercise in a routine without disrupting your session structure. Useful when equipment is unavailable or a movement doesn't feel right today.
Suggestions, Not Instructions
When you're rebuilding strength, the most dangerous advice is confident bad advice. Grip & Balance takes a different position: its progression system uses transparent, rules-based logic — no machine learning, no black-box models — to offer conservative suggestions for strength work only.
You Always Decide
Every suggestion is advisory only. Accept it, dismiss it, or override it entirely. The app will never adjust your programme without your explicit input. You are the authority on your own body.
Deliberately Silent on Rehab
Progression advice is intentionally limited to strength exercises. Rehab and duration work receive no suggestions at all — because cautious silence is more responsible than confident guidance when a recovering body is involved.
Rules-Based, Not AI
The advisor runs entirely on deterministic logic you could trace on paper. There is no artificial intelligence, no neural network, no probabilistic model producing your suggestions. What you see is what the rule says.
History That Tells the Whole Story
Progress is easier to trust when you can see it clearly. Grip & Balance keeps a complete record of every session and surfaces it through exercise-level history and charts — so you can look back at where you started and understand how far you've come.
Exercise-Level Charts
See volume, load, and reps over time for each individual exercise. Charts are simple and legible — designed to answer real questions, not to impress you with complexity.
Apple Health Integration
Grip & Balance reads Apple Health workout data to show estimated energy burned alongside your training — giving you context without requiring a separate app. It never writes to Apple Health, preserving the integrity of your health record.
Read Only, Always
The Apple Health integration is strictly one-directional. Your health data is never modified, exported, or used for anything beyond displaying your own energy context on your own screen.
Your Data Never Leaves Your Device
Privacy in Grip & Balance is not a policy setting or a preference toggle. It is a consequence of how the app is built. There is no account to create, no server to send data to, no analytics to opt out of. The app makes zero network connections — not because we block them, but because none are written into the code.
Zero Network Connections
The app contains no networking code. It cannot reach the internet, so your training data physically cannot leave your device.
Encrypted on Device
Your database is protected by iOS Data Protection — the same encryption that secures iMessages and banking apps. Locked device, locked data.
No Account Required
There is no sign-up, no email address, no user profile. Nothing is tied to an identity because there is nothing to tie it to.
No Third-Party SDKs
No analytics libraries, no crash-reporting frameworks, no advertising identifiers. The app contains only the code needed to do its job.
