9BMetrics connects to your Ninebot One, Kingsong, Gotway or InMotion and logs wheel information: - Speed - Current - Voltage - Power - Pitch and Roll (only in Ninebot) etc. and combines it with the altitude change from the iPhone barometer and the GPS data. Please be aware aware that continued use of GPS running in the background can dramatically decrease battery life. Also if blocking lock screen is enable battery life will be shorter. Each log may be analyzed graphically or exported in a ZIP file that includes a CSV file for each variable and a .gpx file for the GPS data. A special mode allows to debug connection information between the wheel and the original Ninebot application (or other). Another one simulates a real Ninebot One wheel so you may test applications with out the wheel. An Apple Watch module allows to control your speed, remaining battery and km, distance and time simply from your watch while your phone is secure in your barg or pocket.

Explicitly the "no current" one Faster sampling Possibility of changing the riding level directly from the application Much better dashboard when recording Reconstruction of connection process to run independent of User Interface and have better reconnection GPS data is recorded with the workout each 5 m. It is good for long runs, not so good for slaloms etc. (anyway think GPS precision may be about 6 m, sometimes 3m but sometimes 10m). Does not load too much a modern iPhone as uses deferred recording. Tested in a running and skiing application and loads about 6% battery in 1hour for an iPhone 6s. Much better exporting of data Full session data is exported as a .zip There is a file for each variable. I removed the center column with the variable code and changed time to shorter ones as seconds from beginning of recording. First line shows file version, variable and first time date. That way size is much smaller. There is a .gpx file with the track that may be uploaded to different sites or presented with .gpx applications Better graphics and better selection computes statistics of selection between bars. Export option in graphics which allows to export just the selection between the vertical cursors to a .csv file easy to import in excel 1.1 04/13/2016 1.0 03/21/2016
