Paddle further.
Map every stroke.
A quietly powerful companion for kayakers and paddleboarders — built natively for iOS 26 with Liquid Glass, HealthKit, and routes that read at a glance.
What's inside
Tools that stay out of the way until you need them.
Every surface is Liquid Glass. Every reading is tabular. The app respects the water — and your attention.
Route-aware tracking
Polyline colored by pace — green cruises, red sprints. Readable at a glance from the cockpit.
Apple Health sync
Every session writes to HealthKit — distance, duration, active energy. Off by default; you stay in control.
Liquid Glass, everywhere
Stats capsules float over the map; nothing obstructs the water. Designed for iOS 26 from day zero.
Splits that make sense
Per-mile pace. Per-segment elevation. Tabular numerics so numbers don't jitter while you're moving.
Private by default
GPS never leaves your device unless you share a session. No accounts, no analytics, no ads.
Apple Watch-ready
Phone stays dry in the drybag. Start, stop, and glance at splits from the wrist. Coming soon.
On-device by default. Uploads are opt-in.
HealthKit is optional. Revoke anytime.
Wear your PFD. Check conditions. Paddle on.
See it move
Five screens. One flow. Zero friction.
Tap a step or scroll — the phone follows along.
About the developer
One paddler. One app.
In honor of Frank Burke.
SHINE · INDIE DEV
Retail & technology, now building on the water.
Shine is a first-time iOS app developer with an extensive program management background at the intersection of retail and technology. Having worked for both Apple and Meta, he’s currently looking for his next full-time focus. OarSum was born from a personal passion for paddling in the interim.
OarSum Map started as a way to keep track of paddle sessions without dragging a strap-on GPS. It became a quiet love letter to iOS 26, Liquid Glass, and the kind of tool that makes you want to get on the water more often. His grandfather first handed him a paddle when he was seven; this one’s for him.
In memory of Frank Burke, YYYY–2025.
