## What is Newrun?

Newrun is an AI health coach that reads the data already in Apple Health and tells you how today looks and what to do about it.
No need to switch trackers. It reads what your Apple Watch, other workout apps and treadmill sessions already recorded.

[Today's brief]
• Compares sleep, resting heart rate, HRV, steps, workouts and VO2max against your last four weeks
• Shows at a glance whether today needs more recovery or is a normal day
• Gives concrete suggestions for training, sleep, activity and recovery
• The app computes every number; the AI only quotes computed values

[Chat with your coach]
• Ask things like "Can I do a 5K tempo run today?"
• Answers draw on today's data and your morning brief, and the conversation carries on through the day
• If a plan is too much for today, you get the reason and an alternative

[Run coaching]
• Real-time voice coaching tuned to your goal and heart rate
• Zone 2 coaching that nudges intensity to your personal heart-rate range
• Accurate GPS, Live Activity on the Lock Screen, share cards

[Privacy and data]
Health data is read-only and summarized on your device. It is never used for ads or marketing and never sold.
Only if you allow AI data sharing, Newrun sends daily health summaries (sleep, resting heart rate, HRV, steps, workouts, VO2max), your chat with the coach, and your run purpose, elapsed time, distance, heart rate, Zone 2 status, approximate location/weather context, recent coaching conversation, and recent run summaries to Google Gemini through Supabase Edge Functions.
If you don't allow it, nothing is sent to the third-party AI and you get local guidance only.

Newrun's brief and chat are general wellness guidance, not medical advice, diagnosis or treatment. If you have pain or unusual symptoms, talk to a clinician.

Sleep, HRV and resting heart rate appear when they are recorded to Apple Health, for example by an Apple Watch.

## Version history (last 5 releases)

### 2.1.0 — 2026-09-29

What you talk through with your coach no longer drifts away. It stays, as today's plan.
Mindful of how much you've moved today, and the kind of training your week has held.
An easy walk on heavy days, a little further when you feel light.
While you run, the plan you agreed on keeps you company,
and how it felt afterward stays on this device, quietly shaping tomorrow.
A rest day, too, can be the plan.
A coach that remembers yesterday. Newrun 2.1.

### 2.0 — 2026-09-26

Newrun 2.0 — now a coach for your health data.

• Today's brief: reads your Apple Health sleep, resting heart rate, HRV, activity and workouts, and once a day shows how today looks with concrete suggestions
• Chat with your coach: ask anything on Home and get answers based on today's data. The conversation carries on, and you can start a run right from it
• Home is now a single conversation
• Health summaries and chat are now part of what's sent to the AI, so we ask for AI data sharing consent again. Until you allow it, you'll see standard notes
• The brief and chat are general wellness guidance, not medical advice

### 1.10.1 — 2026-09-11

A small polish update.

• Bigger time, distance, and pace numbers on the run screen, with the coaching line easier to read
• Cleaner English and Japanese wording throughout
• New Home: weekly progress ring, recent-run card, and a chat-style composer
• Send today's goal and the coach replies with a short note before you start
• Runs from other apps saved to Apple Health now count toward your weekly progress
• When heat, cold, or rain matters, the coach mentions it once at the start
• Faster start: onboarding is now two steps
• The default coaching frequency is now "Standard", which saves battery and data
• Snappier voice guidance
• Stability improvements

### 1.9 — 2026-06-21

I had a dream with Claude Fable 5.

### 1.8 — 2026-05-26

There were a lot of bugs because of the warmer weather. First of all, we eradicated them hard. Happy running!
