Imua — charge forward

A paddling tracker that actually knows what a stroke is.

GPS, real stroke detection from the IMU, splits, and heart rate from your watch. Plus clubs with chat, a practice calendar, and boat assignments. Built for outrigger, dragon boat, surfski, V1, and SUP — not “Kayak (Other)”.

〽️
Real stroke detection
Counts strokes and live stroke rate from the phone's accelerometer — filtered peak detection tuned to paddling cadence, so waves and chop don't register as strokes.
📍
GPS route, pace & splits
Route map, speed and elevation charts, and splits every kilometer or mile — moving-time aware, so a coffee break doesn't tank your pace.
⌚
Apple Watch app
Record from your wrist: start, pause, and stop on the watch, live heart rate and HR zones, “Start Paddling” with Siri. Workouts save to Apple Health.
🗺️
GPX + shareable links
Every session exports clean GPX. Flip a switch to publish a public link you can drop in a club chat.
🚣
Crafts that exist
OC1 / OC2 / OC6 / V1 / SUP / Surfski / Dragon Boat 10 & 20 — different defaults for different boats. Not “Kayak (Other)”.
📡
Built for the offline put-in
Records fully offline and saves to your phone. Sessions sync to your account when you're back online.
📊
Stats that build up
Lifetime totals, personal bests, and paddling habits — distance, time, strokes, and streaks across every session.
🏝️
Built for outrigger crews
Solo OC1 runs or six seats in the same canoe — track stroke rate, distance, and pace for every paddle.
💧
Heart rate from your watch
Live heart rate streams from your Apple Watch into the session, with time-in-zone breakdowns in your history.

Clubs

Run your whole club from one app.

Create a club, invite paddlers with a link, and keep the feed, chat, and practice calendar in the same place as everyone's training. Members join with roles — owner, admin, coach, member — so the right people can post announcements and set the schedule.

📣
Feed, polls & announcements
Post announcements, updates, and polls to the club feed. Members like, comment, and vote — and you can link a session straight into a post.
💬
Chat channels
Organized chat channels — public or private — with photo and video sharing and push notifications, so race-day logistics don't get buried.
📅
Practice calendar & RSVPs
Schedule practices, races, and socials with meet time and location. Members RSVP going / maybe / not going, so coaches know who's on the water before they load boats.
🛶
Boat & seat assignments
Assign crews seat-by-seat for each event, and bulk-schedule a whole season of recurring practices in one go.
🖥️
Web dashboard
Admins manage members, events, and posts from the browser at imuatrak.app — no phone required.
🔗
Invite links
Grow the roster with a shareable invite link. New members land in the club feed, chat, and calendar the moment they join.
