Jepster uses GPS to track your ride. Furthermore, it supports ANT+™ and Bluetooth heart rate monitors, speed/cadence sensors and power meters.

Real-time data

Jepster provides real-time performance data of your ride. Jepster supports multiple pages which are customizable such that you can have all the information that interests you displayed.

  • Statistics: up to 10 editable data fields
  • Summary: up to 10 editable data fields
  • Lap statistics: up to 10 editable data fields
  • Lap summaries: predefined with 9 data fields per lap
  • Map & statistics: up to 8 editable data fields
  • Elevation: up to 8 editable data fields
  • Elevation chart: up to 8 editable data fields
  • Speed chart: up to 8 editable data fields
  • Heart rate chart: up to 8 editable data fields
  • Power chart: up to 8 editable data fields

Your ride data will be stored on your smartphone as a FIT file.

GPS route navigation

Load GPX tracks or Strava routes (Strava premium members only) which will be shown on the map such that you can easily follow your route (no turn by turn navigation). You can choose to either use Google Maps or OSMdroid (OSMdroid supports offline maps).

Jepster provides you two different pages with a map:

  • STATISTICS & MAP: a section with up to 10 editable data fields and a section with a map
  • MAP: only a large map
Note that the size of the map on the STATISTICS & MAP page depends on the number of data fields chosen.

ANT+™ and BLE sensor support

Jepster supports ANT+™ and BLE sensors. Almost all phones do support BLE, but only a few do support ANT+™. On the ANT+™ website you can find more information about ANT+™ in phones. The following sensor types are supported.

  • Heart rate
  • Speed and/or cadence sensors
  • Power sensors

This product is ANT+™ certified. Visit www.thisisant.com/directory for compatible products and apps.

Search BLE sensors

You can connect Jepster to your Strava account such that you can upload your activities directly from Jepster to Strava.

If you are a premium Strava member you can also download your routes and load the track on the map.

Auto pause

Auto pause feature to automatically pause your activity when stopped riding. You can choose the auto pause trigger value between 0 - 4,5 km/h.

Battery management

Jepster is designed to reliable log your ride data (your ride data is logged every second). But, on the other hand, to optimize battery usage. Main features to optimize battery usage:

  • Battery saving mode option (dark mode). Backgrounds and navigation bar will be black which results in battery saving for AMOLED screens (e.g. Samsung S10)
  • Map and navigation updates only once per respectively 2 and 5 seconds.
  • When riding in dark mode with a Samsung S7 and screen brightness on ~75% my battery last up to 8 hours. When I navigate (so showing a map all the time with a route) the battery last up to 6 hours (in dark mode and screen brightness on ~75%).
