What works well
- Readable at a glance. The speed number is large in portrait and landscape.
- No sensors to pair. Speed comes from GPS, so there's no wheel magnet or Bluetooth setup.
- Trip totals. Start a ride, pause at a café, resume, then End Trip to save a summary: distance, time, average, and max speed.
- Light or night appearance, plus Battery Saver for longer rides.
Know the limits
- Screen must stay on. ClearSpeed measures only while it's open on screen. Keep-screen-awake is on by default; locking the phone pauses measurement.
- Battery. Screen plus GPS drains faster than a dedicated bike computer. Battery Saver helps; a top-tube battery pack helps more on long rides.
- No cadence, power, heart rate, elevation, route map, or Strava/Health export. For training analysis, a cycling app or bike computer is the better tool.
- Trees and cliffs can weaken GPS; the app shows Weak GPS rather than guessing.
Setup tips
- Use a secure stem or handlebar mount; check it before descents.
- Choose MPH or KM/H before you ride and start the trip while stopped.
- Don't tap the screen while riding in traffic — glance only.
