About CdaCrr - Bike computer with ae APK
Table Of Contents
Description
Bike computer to ride faster by improving your aerodynamic position and testing gear/equipment. Among other data, it monitors CdA (drag*area) and Crr (rolling resistance) coefficients, during races or dedicated testing sessions. It requires BLE or ANT+ power and speed sensors, and an anemometer (option, see below) for improved precision.Powermeters successfully tested are:
-Power2Max
-Assioma pedals
-PowerTap hub (records speed so additional sensor is not needed)
Speed sensors currently supported are:
-CycleOps
-Garmin (Warning: old Ant+ Garmin model is not working with the app)
-Wahoo
-CooSpo
Avoid any magnet less speed sensor, their accuracy is not as good.

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
Don't hesitate to contact us if you have any questions or concerns.
