Start on Apple Watch or iPhone. See one paddle across every glance, then turn routes into records, water memory, and on-device Paddle Intelligence on supported hardware.
Oarsum turns every paddle into a record worth keeping.
Built native for iPhone and Apple Watch, it maps where you've been, names the water you paddled, and explains what all of it adds up to.
START ON EITHER WRIST OR POCKET
Start on iPhone or Apple Watch. Whichever accepts Start owns the paddle. Apple Watch records, recovers, and saves complete sessions on its own, with or without your iPhone along for the ride. The other device becomes a live cockpit, and finished Watch paddles land in your iPhone library automatically.
MAPS THAT REMEMBER
Completed paddles open already framed. Pull back and the summaries adapt, with nearby waters tappable straight from the map. Recolor any route by speed, repeat heat, month, or distance, and the same line answers a different question.
WATER WORTH NAMING
Oarsum identifies where you paddled with evidence, not a guess. Water Intelligence learns from your naming over time, and repeat visits build a map of the places that keep pulling you back.
A HISTORY THAT EXPLAINS ITSELF
- Activity: 7-day, 4-week, year-to-date, and all-time comparisons, streaks, and a 26-week paddle heatmap
- Waters: coverage, new water versus repeat, ranked by visits
- Performance: pace, efficiency, speed consistency, stroke economy, and honest evidence thresholds instead of charts built on three data points
- Records: every record leads back to the paddle that earned it
- Paddle Intelligence: ask a real question about your paddling and get an answer grounded in your actual trips, on device with Apple Intelligence on supported hardware
ON THE WATER, AT A GLANCE
- Light Rail: sunrise, sunset, and the next light boundary, centered on now
- Weather Rail: temperature, wind, UV, and rain chance in one narrow strip
- Speed Rail: the key to your route's speed colors while you're still paddling
- Stroke rate detected from Apple Watch motion
- Live Activities on the Lock Screen, StandBy, and Dynamic Island, plus widgets and the Watch Smart Stack
- Optional HealthKit sync saves each paddle as a workout
NO ACCOUNT REQUIRED
Your routes, trip history, and Health data stay on your device. Community Water Activity is optional and off until you turn it on, and even then it shares coarse water context that helps Water Intelligence improve, never your route specifics.
FREE AND OARSUM+
Recording, routes, history, lifetime totals, Apple Watch, HealthKit, and Paddle Intelligence are free, along with three Deep Detail paddles each month and two GPX exports to start.
Oarsum+ removes the limits: unlimited Deep Detail, the full performance and water intelligence, record progression, and unlimited exports.
Oarsum+ is a Seasonal Pass (every three months) or an Annual Pass, auto-renewing until canceled. Purchases are verified and restored through your Apple Account.
Be it a quiet morning on a familiar lake, a training row, or a weekend on water you've never seen, Oarsum makes each one count for something.

Really cool idea, can’t wait to see future improvements
mikepat_
As someone who tracks their running distances, I like the idea of doing the same when I go kayaking. Now I can keep track and push myself further through the app instead of timing myself and keeping my own notes. Great work! Hopefully we can add friends soon and also create events for group kayaking. I’d love to meet others who have similar interests through this app.
Find inner peace
S. Ali 125
This is a great app for keeping track of how far you paddle. Nothing like me on the open sea, paddling away, trying to find inner peace. Who want the hassle of messing with a map. Surely, not I. When I get lost at sea. This app helps guide me home.
Your paddle now reaches every glance, and your history finally explains itself.
OARSUM OPTIMIZATION
The native Swift app is now more efficient, with faster launch, smoother navigation, leaner background recording, and more durable recovery.
PADDLE INTELLIGENCE
New. Ask a real question about your own paddling, like how far you've gone, how your speed is trending, or which waters you return to, and get an answer grounded in your actual trips. It runs on device with Apple Intelligence on supported hardware.
STATS, REBUILT
A new Overview leads into four screens that each answer one question: Activity, Waters, Performance, and Records. Jump straight to All Time, Last 7 Days, or Streaks; read a 26-week paddle heatmap; and open the exact paddle behind any record instead of trusting a detached trophy. Fun facts about your totals now refresh on their own.
MAPS THAT OPEN READY
Completed paddles open already framed with a prepared overview. Repeat-route heatmaps reveal the water you keep coming back to, nearby paddles are tappable straight from the map, and new appearance and route-color options let the same route answer a different question.
THE UNIFIED PADDLE COCKPIT
Elapsed time, distance, effort, cadence, strokes, conditions, and controls now stay aligned across the iPhone Lock Screen, Dynamic Island, StandBy, and the Apple Watch Smart Stack.
INDEPENDENT APPLE WATCH RECORDING
Start, record, recover, and save a complete paddle on Apple Watch, even with your phone ashore. Finished Watch paddles land in your iPhone library automatically.
LIGHTER ON YOUR BATTERY
Background recording was rebuilt around wall-clock updates instead of constant wake-ups, with a durable route recorder that checkpoints as you paddle and recovers cleanly after an interruption.
ALSO IN THIS RELEASE
- Clearer Oarsum+ presentation, with the free monthly Deep Detail allowance shown where you spend it. Paywalls are no fun, but they can at least be informative.
- No account and no sign-in anywhere in the app; subscriptions are verified through your Apple Account.
- Updated in-app Privacy and Terms.
BUG FIXES
- Fixed a purchase screen that could show incorrect pricing
- Fixed an overlap between the on-water rails and the map legend
- Fixed a hang when opening trip detail
- Fixed the trip map snapping back to your location while you were reviewing a paddle
