RowyGlowy is the digital stroke rate analyzer, paddling rhythm metronome, and water workout logbook built for kayakers, rowers, dragon boat crews, and SUP paddlers who take their cadence seriously.
From cadence training to post-session review, RowyGlowy keeps the water, the rhythm, and the record all in one instrument panel.
Dial in target stroke-per-minute intervals from 15 to 60+ SPM, tuned for endurance long-distance paddling or high-intensity sprint sets.
Distinct audio signals mark the catch, drive, and recovery phases so your body learns the full stroke cycle, not just the beat.
Train under pressure with gradually increasing stroke tempos designed to sharpen form when fatigue sets in.
Place your device in your vessel and let iPhone sensors automatically detect and count stroke frequency in real time.
Measure interval variance between strokes to build a smoother, more efficient drive phase stroke after stroke.
Estimate your split time per 500m based on current SPM and logged water drag notes, no guesswork required.
Log water clarity, current speed, wind direction, and weather notes for every outing you record.
Track paddle length, blade surface area, boat model, and seat setups across every craft you paddle.
Analyze stroke rates, run tempo metronomes, and log water sessions anywhere — no internet connection needed, ever. From open bays to remote rivers, RowyGlowy works exactly where your training happens.
This is a real, working SPM metronome. Set your target cadence and press start to hear and see it pulse.
Runs entirely in your browser with the Web Audio API — the same on-device principle RowyGlowy uses on iPhone, with zero data ever leaving your device.
We're a small crew of paddlers, rowers, and mobile engineers who got tired of guessing our cadence mid-session. RowyGlowy started as a personal stroke-timing tool on a kayak dashboard and grew into a full digital stroke rate analyzer, rhythm metronome, and water workout logbook — built by people who'd rather be on the water than in front of a screen.
Our mission is simple: take the guesswork out of maintaining consistent stroke cadence and power output. Whether you're chasing a smoother drive phase or trying to hold a target SPM for twenty straight minutes, RowyGlowy gives your rhythm a reliable, honest reference point every single stroke.
For kayakers and SUP paddlers refining technique, dragon boat and outrigger crews syncing timing across the whole boat, and rowers who just want a lightweight offline stroke rate meter — RowyGlowy hands you an audio metronome, an accelerometer-based stroke counter, and an environmental logbook, all working together in one focused app.
Steady stroke. Clear water. Glowy rhythm.
RowyGlowy collects nothing. There is no sign-up, no account, and no form to fill in. We do not gather your name, email, location, device identifiers, or any personal or usage data at any point while you use the app.
Because no information is ever collected, none is used, analyzed, profiled, or sold. There is no advertising engine and no analytics pipeline watching your sessions — your stroke data belongs to you alone.
Every SPM target, accelerometer stroke count, split-time calculation, environmental note, and equipment entry is stored locally on your device only. RowyGlowy has no cloud backend and no remote database, so nothing you log is ever uploaded anywhere.
RowyGlowy does not integrate third-party analytics SDKs, advertising networks, or tracking scripts of any kind. The metronome, stroke consistency ratio, and logbook run entirely on-device without contacting outside servers.
Since your stroke rate history, equipment specs, and water condition notes never leave your iPhone, there is no transmission for anyone to intercept and no external server for anyone to breach. Your local data is protected by the same security model as the rest of your device.
RowyGlowy does not knowingly or unknowingly collect data from anyone, including children under 13. Because the app is fully offline-first with no accounts or data collection of any kind, it is compliant with the spirit of COPPA by design.
You are always in full control. There are no accounts to manage and no remote records to request deletion of. Deleting the RowyGlowy app from your device removes every local log, metronome preset, and equipment entry completely and permanently.
If our data practices ever change, this policy will be updated within the app and on this page with a revised effective date. Our commitment to offline-first, zero-collection design will always be reflected accurately here.
