surge15 · iOS
A run-tracking app for functional training without a track. Build a fixed running loop, run it anywhere, and watch your times actually drop — no account, nothing leaves your phone.
No track? No problem. surge15 keeps your route actually fixed session to session — so every comparison is a fair one.
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.
Run multiple laps in a single session and instantly see each split against your personal best and average. Progress you can feel, then prove.
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.
Log the full functional mix — lunges, burpee broad jumps, rows, wall balls, and rest — each tracked in its own units alongside your runs.
Build reusable workout templates — "Run 400m, Lunge 24m, BBJ 10 reps" — and turn any plan into a tracked day with a built-in checklist.
Browse past sessions in a calendar grouped by morning, afternoon, and evening, with active-day markers and quick summaries at a glance.
Six exercise types, each with the right units — so a full functional session lives in one place.
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 stored on our servers — because there are no servers.
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 "you" for us to track.
