![]() Data Politics / Privacy: Many commercial / proprietary apps provide centralized services, vital / health and fitness data is often sent to other countries / beyond legal and social control Decentralized networks to share, sync and process health and fitness data are currently still in developments - at the moment users basically lose control over their data when they press the start button of their app.In general these services require an API key and valid / profitable business model. ![]() Weather: While several weather providers offer free start packages, these offers are generally very limited.In general these services require an API key and valid / profitable business model.Įxamples: Google (recurring $200 credit), Mapbox (50,000 monthly active users, 50,000 geocode requests / mo, 50,000 directions requests / mo, 50,000 Matrix elements / mo) Here (250K transactions per month, 5K SDK monthly Active Users, 250 Managed Assets per month) MapCat (100,000 Visualization sessions*/mo, 3,000 Search requests/mo, 3,000 Directions requests/mo), Graphhopper (Credits 500 per day, Max. Routing: While several routing providers offer free start packages, these offers are generally very limited.Maps: With OpenStreetMap an excellent provider of maps is available.ANT+: Ant+ relies on proprietary libraries, which are not published as open source (Not FOSS) (See: ), which led to the F-Droid removal of RunnerUp.Bluetooth: (Some of) The Bluetooth specifications are standardized, heartrate and cadence should generally work, but many hardware manufacturers of fitness trackers, GPS watches or electronic shifting systems rely on proprietary formats (Not FOSS).Hallo, as stated before, there are a few challenges for such a fitness app / implementation, some of them have been mentioned by previous posters: Once you have your ride data colllected you might be interested in the excellent GoldenCheetah (PC software, GPL v3, Linux, Mac OS X, Windows) for post ride analysis. This helps if you ever plan to see your data both on the smartphone and a dedicated bicycle computer. There might be two drawbacks though: a) it’s for runners ) b) it’s been excluded from fdroid builds because it uses ANT+ libraries (not compatible with free/libre and RunnerUp currently cannot be compiled without).Įventually look for speed and cadence sensors which support both ANT+ and bluetooth. I haven’t used it myself but it seems to have lots of things in place. Maybe also RunnerUp is an application to watch. to BRouter “Let’s get serious about bike routing”) and it has an API other apps can connect to) OsmAnd is pretty flexible (you probably know, just stating: the data it operates on is free/libre, can be used offline, its routing cost functions can be changed, the underlying routing engine can be changed (e.g. Map and bike routing could be done with OsmAnd (on fdroid too). Might have overlooked something - glad if someone gives a good pointer! I have been searching for this as well but I am not aware of such an bicycle app.
