UltraKayak
Apple Watch kayak recorder
Free
UltraKayak is an Apple Watch kayak training recorder for paddlers who want a focused, honest record of every session.
Start a session on Apple Watch, paddle with a locked, glove-friendly screen, and your motion and GPS data transfers to iPhone automatically — with visible progress, resumable transfers, and a receipt when each session is stored. All data stays on your device.
On iPhone, review each session in depth: your route on the map with speed coloring, distance, duration, average speed, stroke rate, distance per stroke, and per-kilometer splits. Read heart rate from the Health app when you also record a workout. Add notes, gear, and manually logged tide conditions to keep the full story of each paddle.
Over time, UltraKayak builds your personal baseline and shows weekly trends, so you can compare any session against your own recent level — honestly: data that was not captured is shown as missing, never faked.
Key features:
- One-tap start on Apple Watch with water-lock protection.
- Reliable Watch-to-iPhone transfer: progress, resume, and stored receipts.
- Route map with speed coloring, per-kilometer splits, up/downstream comparison.
- Stroke rate, stroke count, and distance-per-stroke analysis.
- Heart-rate curve read from the Health app (when recorded with a workout).
- Personal baseline and weekly trends.
- Notes, gear, and manual tide logging. Chinese and English interface.
- iPhone GPS-only recording when you paddle without a watch.
- No account. No cloud. Your data never leaves your devices.
UltraKayak is for sports training review only. It does not provide medical advice, diagnosis, treatment, rehabilitation guidance, or injury-prevention recommendations.
