I studied Industrial Engineering and Management with an IT specialization. I learned the basics during several courses. I started learning Android development with an online tutorial just before I started working on the Jepster app.
Creating the app in such a way that I would always record the ride data. Especially, when the app is not visible on the screen e.g. when making a picture, screen off, or just making a a phone call the app should still record in a reliable way.
Tom Wassink (born 1984) lives in the Netherlands with his two kids (born in 2014 and 2017) and his wife. He really likes sports and especially cycling (road and mountain biking). Tom has a master's in Industrial Engineering (IT specialization) and started his career as an IT auditor at Ernst & Young in 2009. Since 2012 Tom has held several positions at Royal Avebe and currently, he is the manager of the Functional Application Support team of the ICT department.
Ziggo Go (part of Vodafone) app I really like because it gives you the opportunity to watch live sports events everywhere. Furthermore, I like Strava, Spotify, Google Maps, and News apps.
I started in 2012 and it took me 3-5 years before I launched an initial version in the Google Play Store. Since then, I still spend time to add new functions and keep it up to date. As I have a full-time job and two young kids, I have to do developments in the spare time left.
The minimum requirements were to be able to reliable record a ride with GPS data, ability to connect to ANT+ sensors (e.g. heart rate monitor, speed/cadence sensors, and a power meter), and to show a GPX route on a map together with data fields. Next to that battery consumption needed to be acceptable.
I’m most proud of the recently added climb function and the ability to easily change data fields shown. Next to that it is very reliable. It crashed sometimes after I did an update, but I never lost a part of my ride. The uniqueness of the app is the combination of the looks, features and that it is for free and without advertisements.
As the number of users of the app has grown with more than 600% over the last 9 months I got a lot of questions and feature requests. So first I have to finish the manual to make some things clearer.
One of the major new features which I would like to develop is Live Strava Segments, but as Strava recently changed their interface I have to think about the opportunities left. Other features are online tracking for supporters/safety feature, turn by turn navigation (might be a “premium” function as libraries are not for free, at least the ones I like), support of additional ANT+ profiles, more data fields, different font sizes and multiple user interfaces for the layout.
Provide feedback (in a positive way ;-)) on what they like and do not like about the app.
Also features requests can be send to me to keep me inspired for new functionalities (although I already have a long list of requests…). And of course share their experiences with others!

- GPS route navigation
Load GPX tracks or Strava routes 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 OpenStreetMap (Openstreetmap supports offline maps and has more functionalities).
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.

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.
Strava & TrainingPeaks
You can connect Jepster to your Strava and TrainingPeaks account such that you can upload your activities directly from Jepster to Strava/TrainingPeaks. Furthermore you can directly load your Strava routes.
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.
Among others, the following data is available to be displayed (real-time, averages, maximum values): Altitude
