surge15 · iOS
Your spot — a park, a field, a stretch of beach. Map your loop once, run it on repeat, mix in strength work, and see if you’re getting better at the whole session.



surge15 keeps your route fixed. So when your time drops, you know it's real.
Everything you need to train hard and measure real progress — not just another distance counter.
Build a GPS running loop with turn-by-turn directions. A 20-meter start gate and auto-stop keep every lap the exact same distance, so the numbers mean something. The shorter the loop, the more versatile it gets — a 50m loop works just as well as a 500m one, and Surge handles the lap math.
Run multiple laps in a single session and instantly see each split against your personal best and average. Progress you can feel, then prove.
A plan sequences your entire workout — runs, strength, rest — in order. Execute it, check off each item as you go, and come back to the same plan next time knowing exactly what you’re beating.
Log the full functional mix — lunges, burpee broad jumps, rows, wall balls, and rest — each tracked in its own units alongside your runs.
On-screen overlays and haptic buzzes call out every turnaround mid-run — left, right, or around — so you stay on route and on pace, eyes up.
Browse past sessions in a calendar grouped by morning, afternoon, and evening, with active-day markers and quick summaries at a glance.
surge15 is private by design — not because of a policy, but because your data never leaves your phone in the first place.
No sign-up, no email, no password. Download the app and start training — there's nothing to log in to and no profile to create.
Your routes, sessions, and times live entirely on your phone. Nothing is uploaded, synced, or backed up to us — the only exception is a route you deliberately choose to share.
The only data the app uses is GPS, purely to measure your run. We never store it and never tie it to you — there's no account or identifier for us to track.
Built a loop worth running? Send it to a training partner — without giving up an ounce of your privacy.
When — and only when — you tap Share, the route's map coordinates are uploaded and you get a short share code to text to anyone. Nothing is ever sent automatically.
Your friend types the code into surge15 and the loop drops straight onto their phone — turns, distance, and all — ready to run.
A shared route carries only its coordinates. No name, no account, no device or network identifiers ride along — so it can never be traced back to who sent it. Codes stop working after 48 hours.
