Train with context
Train with
context.
Berin treats your body as a system: strength is one signal among sleep, rest and recovery. An AI agent knows your full context and tells you what to do today.
Coming soon on iOS · Read-only Apple Health

The thesis
The body is a system.
You're not just how much you lift. Berin reads the signals that matter and cross-references them to decide how you train today, no guessing.

Berin Guide
An agent that knows your full context.
Berin Guide knows your injuries, your sleep, your HRV, your training and your recovery. It builds evidence-based routines and gives you the daily recommendation. You approve; nothing applies without your OK.
- Routines with reasoning
- Evidence-based frequency, volume and progression, filtered by your restrictions.
- Daily recommendation
- It looks at last night's recovery and how your week is going, then tells you what to do today.
- AI proposes, you approve
- Every change arrives as a readable proposal. Approve or reject. Nothing agentic without your OK.

The app
Inside Berin.
Real captures from the app, with demo data. Tap through each module.
Ask for a routine and it builds the whole thing.
It asks what's missing, reasons with evidence-based method and respects your injuries. Every action arrives as a proposal you approve or reject.


Your context, every morning.
Sleep, recovery and your week's activity on one screen, with Berin's daily recommendation and what's on for today.


Routines with reasoning.
Days, blocks and exercises with detailed technique, target weights per cycle week (W1-W4), RPE and rest. With medical warnings where they matter.


Train with the clock running.
Move block by block logging sets, with a rest timer, notes and deviations in real time. Everything gets recorded.


Understand your rest.
A transparent sleep score (you see how it's calculated), the night's hypnogram and vitals, read from Apple Health.



Everything that happens, stays.
A process calendar with your sessions and Watch activity, monthly summary, volume lifted, PRs and yearly totals.


Medical safety
Your restrictions are a first-class citizen.
You tell it your injuries once and they always travel in the context. The AI never proposes anything that contradicts them. Neutral neck, safe loads, per-exercise alerts.
Lumbar protrusions and cervical stenosis → no behind-the-neck pulldowns, good mornings or overhead barbell press.
Your process
Everything that happens, stays.
Live sessions, set-by-set logging, sleep with score and hypnogram, a process calendar and PR detection. The memory of your training is also the AI's input.
Live session
Running clock, block-by-block progress, notes and deviations in real time.
Sleep & recovery
Transparent 0-100 score, hypnogram and nightly vitals from Apple Health.
