## What is Oxygon?

Oxygon plans what you will eat, drink and run — checkpoint by checkpoint — plans the course you will run it on, coaches the weeks before, and then measures whether it worked.

COURSE PLANNER
Draw a course on real roads, or have one suggested from where you stand: how far, loop or out-and-back, flat or hilly, quiet roads, trails. See distance, climb, surface and your own estimated time as you draw. Save it, attach it to a race plan, export a GPX for your watch.

A COACH THAT READS YOUR YEAR (BETA)
Connect Garmin through intervals.icu, Strava or Apple Health and the interview asks you less — it already sees your volume, your biggest week, your longest run and your threshold. The plan is periodised to your race, and the Coach tab is a conversation: your week, today's session, proposals when the plan should bend, and a chat that answers from your own numbers and offers changes as buttons.

FUELLING BY CHECKPOINT
Set your hourly water, carbohydrate and sodium, attach the course, and Oxygon spreads the doses across the stops with the clock time you should reach each one. Scan a gel or drink and its nutrition arrives from Open Food Facts; a catalogue of products is built in.

LIVE
GPS distance and pace, heart rate from a Bluetooth strap, auto-pause that knows a red light from a slow climb, glucose from a CGM. Share a link and your crew follows your position, pace and heart rate. Ask the race assistant a question mid-run and it answers against your own plan — with no signal it keeps answering from rules on the phone.

CONDITIONS
Pull the forecast for your course and your race day, and the fuelling is built against the heat you will actually meet.

AFTER
Pace, cardiac drift, energy burned split into carbohydrate and fat, heart rate against the course profile, power on rides, the route you ran and the shoes you ran it in. Calendar, list and charts of everything planned and everything done.

CALCULATORS
Pace, critical speed, race predictor, VO2max, heart-rate zones, training paces, grade-adjusted pace, treadmill pace and calories burned. Every one works offline, with no account.

A LIBRARY OF REAL RACES
Courses with their distance, elevation and typical conditions, ready to plan against.

Oxygon is free. There are no ads, no analytics and no tracking. An account is optional and exists to back your plans up and sync them between your iPhone, Android phone and the web at my.oxygon.app. Oxygon Pro adds the coach chat, more than one plan at a time, crew tracking and Progress & Insights.

## Version history (last 4 releases)

### 1.3 — 2026-09-09

COURSE PLANNER
Draw a course on real roads, point by point, or tell Oxygon how far, how hilly and what shape you want and pick from eight suggestions. Distance, climb, surface and your own estimated time as you go. Save it, attach it to a race plan, export a GPX for the watch. Activities → + → Plan a course.

THE COACH IS A CONVERSATION
Your week and today's session in one card, proposals when the plan should bend, and a chat that grounds every answer in your own numbers. When a change makes sense it arrives as a button — move, shorten, skip, add a session — never applied behind your back.

RACE DAY
Checkpoints tick themselves off by GPS as you pass them. Tick one yourself and say what you actually took; the stops ahead re-plan around it and one line tells you what moved. Took something that was never in the plan? Add it from the catalogue and it counts from there. Every stop you set by hand stays yours.

ACTIVITIES, ONE PLACE
Calendar, list and charts of everything planned and everything done. Treadmill runs, the shoes you ran in, power on rides from a meter.

GARMIN AND MORE
Garmin through intervals.icu — runs, rides, resting heart rate, HRV, sleep and VO2max reach the coach. Strava stays as a source. Mark a race in intervals.icu and the coach honours it.

ALSO
One icon set and one design on iPhone, Android and the web at my.oxygon.app. Sync that never lets an idle device overwrite your plans. Dozens of small fixes.

### 1.2 — 2026-08-20

- Garmin, Coros, Polar, Suunto and Wahoo now connect directly through intervals.icu: your runs arrive with heart rate and route, plus HRV, sleep and resting heart rate. Settings > Connected apps.
- Shoes: track each pair's kilometres. Tag a run's pair in the debrief - the default pair tags itself at the finish - and get a nudge when one passes its replace-by distance.
- Settings polish and fixes.

### 1.1 — 2026-08-16

Glucose you can trust at a glance. An expired sensor keeps broadcasting its last reading forever — the tile used to show that number as though it were live. It now says the sensor has expired.

Heart rate follows you between devices. Open a finished run on your other iPhone or iPad and the trace, the average and the cardiac drift are all there.

Rate how it felt. A quick 1–10 after every run, with room for a note. It feeds your training load, so an easy hour and a hard hour finally count differently.

Your crew sees the whole race. Live charts no longer thin out as a race gets longer — the same detail at 250 km as at 10 km.

Also: the last checkpoint ticks itself off at the finish, treadmill runs are marked in your activity list, and holding the chart reads out every value at that point.

### 1.0 — 2026-08-14

No release notes.
