• Power chart: up to 16 editable data fields

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

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 16 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.

Routes with elevation data will be analyzed and the climb profile will be visible when you are close to (less then 500m) or on the climb.

A climb has to contain at least a part with an average grade of 3% over 500 meters. It can have a small decline (average grade of a part with a decline has to be at least -0.5% over 1.500 meters).

Note: algorithm may be adjusted in the future or flexible based on terrain (different parameters for e.g. a hilly route vs. a mountain route).

Based on the climb the following data fields are available on every page:

• Distance to top
• Average grade of climb section
  (sections are 250m, 500m or 1.000 meters depending on length of climb)

Jepster provides one page with the climb profile:

• CLIMB: a section with up to 16 editable data fields and a section with the climb profile, average grade of climb, distance of climb and average grade of climb section

Bar colors:

• Very easy (<1%): Green
• Easy (1% =< 4%): Yellow
• Medium (4% =< 7%): Light Orange
• Difficult (7% =< 10%): Dark Orange
• Very difficult (10% =< 13%): Light red
• Extreme (=< 13%): Dark red

Note that the size of the chart on depends on the number of data fields chosen.

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
• Bikeradar (Garmin and Bryton)
  
  

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

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

You can also download your planned bike workouts from TrainingPeaks (workouts planned up to 7 days ahead).

If you are a premium Strava member you can also download your routes, load the track and your starred Strava Segments on the map. Check the Strava Live Segments manual for more information (implementation somewhat different compared to other implementations.)

You can download your planned bike workouts from TrainingPeaks (workouts planned up to 7 days ahead) or load a Zwo (Zwift Workout) file. Jepster will give you a written and visualized overview of the workout and provide you with real-time information about the duration left and your current power compared to the lower and higher targets (heart rate limits can also be shown).

Jepster will automatically start the workout when the activity is started and start a new lap when the next workout step starts.

A workout can be paused or the steps duration time can be adjusted. Furthermore the power target can be adjusted.

Look 150 meters or more behind you with a bike radar (compatible with Garmin and Bryton). The radar detects up to 8 different vehicles, which are displayed directly on your screen (data pages). Additionally, there is an audible alert that informs you whether a vehicle is registered or if the danger has passed.

The sound alert also functions when the display is off.

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 S26)
  
  
• Map and navigation updates only once per respectively 2 and 5 seconds.
  
  
• When riding in dark mode with a Samsung S25 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).
