Lapper: Lap Timer + Coach

Lapper turns your iPhone or iPad into a smart lap timer and real-time audio assistant for all lap-based sports. Whether you're driving, cycling, skating, or running laps, Lapper gives you detailed insights without the need for extra hardware. No complicated setup. No external sensors. Just press start and move. Lapper takes care of the rest—lap detection, timing, audio messages, and data sync happen automatically.

- Just drop a start/finish point on the map and begin your session. Lapper automatically detects every lap using GPS with high precision. Under optimal conditions, lap timing is near-perfect. Even with weaker signals, accuracy stays within ±1s.
- Get voice feedback in your ears, lap after lap. Choose what type of message to receive—lap time, performance progression, or best lap—and adjust message length for better focus. Stay in your zone while staying informed.
- Coach Mode lets you connect live with your coach, spotter, or teammate. Talk in real time and share full session data instantly, over Bluetooth or the internet. It’s like having a pit wall in your pocket.
- After your session, review detailed performance data. Compare lap times, progression, and performance deltas. Replay your route from above with satellite view and understand exactly where you gained or lost time.
- Lapper also detects performance trends. Whether you're improving, plateauing, or regressing, you’ll see the trend per lap, per session, and across tracks. These trends help you adapt your training and recognize breakthroughs.
- Save your tracks and sessions for any sport. Lapper remembers your favorite layouts and lets you build your personal track library, whether you're on a racing circuit, a velodrome, or a loop in the park.

Built for iOS and iPadOS, Lapper takes advantage of all Apple technologies and sensors, with no extra dongles, beacons, or wearables needed. Just mount your phone and go.
Train smarter. Get faster. One lap at a time.
