## What is SR Companion?

A companion app for the SmartRow rowing sensor. Connect via Bluetooth to see real-time rowing metrics, force curves, and power data on your iPhone, iPad, Apple Watch, or Mac. Available in English, German, French, and Spanish.

SR Companion is an independent, third-party companion app for the SmartRow rowing sensor — not affiliated with, endorsed by, or developed in cooperation with SmartRow or Ergometer Innovations B.V.

### 4/5 — Great basic rowing app!

*2026-07-14*

App provides great customization and a better interface than the official SmartRow app. Hoping we can get actual workouts soon. I would switch full time if this app had programmable intervals.

## Version history (last 5 releases)

### 1.71 — 2026-06-18

Fixed a few interface labels that could appear in English instead of German, French, or Spanish — all four languages are now fully translated.

### 1.70 — 2026-06-11

New name: SR Companion
- The app is now called SR Companion (formerly SmartRow Companion). At the request of the team behind the SmartRow hardware, the name no longer leads with "SmartRow" — making it clear this is an independent, third-party companion app, not affiliated with or endorsed by SmartRow / Ergometer Innovations B.V.
- Nothing else changes: your sessions, settings, Strava and Apple Health connections, and iCloud history all carry over automatically. No re-pairing, no re-login.

Peloton and more fitness apps
- New "Alternate broadcast name" setting lets the Peloton app discover your rower for its rowing classes
- New "Relay heart rate signal" setting sends your heart rate to apps that don't read it over FTMS — just pair SR Companion as a heart rate monitor
- The broadcast (and heart rate) now turn on as soon as you enable them, so you can connect in your fitness app before you start rowing

Reliability
- Fixed an occasional glitch in the live force curve on harder strokes — the curve now renders cleanly across the full stroke

### 1.60 — 2026-05-01

Connect Screen Redesign
- Updated visuals with a glowing rower-with-halo motif that flows seamlessly across every state: idle → scanning → connecting → connected
- Find My SmartRow button pulses with a blue glow on the landing screen, matching the green glow on Start Session
- Cancel reshaped as a tidy capsule pill instead of a full-width button — no more spanning the screen in landscape

Reliability Fixes
- Apple Watch HR session no longer gets stuck streaming when the phone app is briefly opened and dismissed within a second or two
- A backgrounded phone on the Ready-to-Row screen no longer holds or reacquires the BLE connection to the rower from another room
- Cold-launch with a saved rower no longer briefly shows the saved-device idle screen before flipping to "Connecting…"

Misc
- Default appearance for new installs is now Dark mode (was Auto). Existing users keep whatever they had set in Settings

### 1.51 — 2026-04-23

Apple Watch Companion
- New Apple Watch app — use your Apple Watch as a heart rate monitor during workouts
- Auto-launches and starts streaming when you open the iPhone app
- Seamless reconnect after sleep, app switch, or reachability gaps
- Status card on the Session Ready screen shows connection state and live HR
- Backgrounding the phone ends the watch session immediately; foregrounding reconnects
- Fully localized (English, German, French, Spanish) and follows the iPhone in-app language

Stroke Score — New Technique Feedback
- Compare every stroke to a target force curve and see how your technique stacks up
- The reference curve follows the "Grinko style" described by Dr. Valery Kleshnev — strong leg-drive and an early peak
- Dynamic reference: the target curve is recalculated on each stroke from your current stroke rate and peak force, so the target stays realistic as you accelerate or ease off
- Every stroke is scored 1–10 on two independent dimensions:
  • Timing — how close your peak force lands to the expected position in the drive
  • Shape — how closely your overall curve matches the target, including smoothness
- Color-coded scores (red, orange, yellow, green) let you read your technique at a glance
- Force curve y-axis scales dynamically so peak force always sits at 90% of plot height, with an orange dashed peak-force line for quick reference
- New "About Stroke Score" info screen explains the methodology and cites the source research (Kleshnev, 2006 & 2020)

Polish & Fixes
- Workout screen no longer flashes a cleared state when ending or discarding a session
- Work overlay chip is now fully opaque

### 1.50 — 2026-03-26

Collapsible Workout Layout
- Tap any metric section to collapse it into a compact bar — tap again to expand
- Distance, pace/speed/calories, work overlay, and power header are all collapsible
- Smooth animations on expand and collapse
- Your layout preference is remembered between sessions

Typography Refresh
- Workout metrics now use rounded fonts with stable digit widths for a cleaner look

Power Graph
- Rolling window size is now configurable — choose from 25 to 200 strokes in Settings

Mac Support
- Run SmartRow Companion natively on your Mac
