# Session tracking

*Your session, measured. Sendit uses your phone’s sensors to track height, leaps, lean and time — with a graph for every go you can save and share.*

Phone-sensor session tracking: height gained, leaps, lean and time, recorded across multiple goes, with a detailed per-go activity graph, heart rate and health sync.

- **Height** — Up & down
- **Leaps** — Dynamic moves
- **Lean** — Steepness
- **Per-go** — Activity graphs

### Height, leaps, lean and time.

*From your phone*

Drop your phone in your chalk bag and Sendit reads its sensors — the barometer estimates height gained, the accelerometer catches your leaps and dynamic moves, and the gyroscope reads the wall’s lean. No watch, no extra hardware needed to start.

- Height up & down
- Leaps + dynamic moves
- Lean / steepness + time

### A graph you can drill into.

*Every go*

Record multiple goes in one outing, each with its own difficulty and notes. Every go gets a detailed activity graph — height over time, heart rate if you’re wearing a strap, and a marker for every leap — and they combine into one session you can save and post.

- Multiple goes per session
- Detailed activity graph
- Editable grade + notes per go

### Post the session.

Save a session to your logbook and share it as an activity post — the graph and the numbers render right in the feed.

### FAQ

**Does it work on any phone?**

Tracking uses the phone’s barometer and motion sensors on a real device. The numbers are approximate — great for trends and comparing sessions over time.

**Can I record more than one climb?**

Yes. Record multiple goes in one outing; each has its own graph, grade and notes, and they combine into one session you can save and share.

**Do I need a watch?**

No — it runs from your phone. A Bluetooth heart-rate strap is optional if you want heart rate on the graph.
