What’s New

Version 1.6.4

1.6.4 fixes a bug that prevents the app from accessing iCloud Drive. 1.6.4 restores iCloud Drive functionality for recording log files and accessing other files.

Fixes and Improvements in Previous 1.6.x releases:

- Fix for ASC log file generation: While all the data bytes are recorded to the log, the "length" field is improperly calculated. Apps that consume ASC log files and obey the data length field will ignore bytes, resulting in signals that appear to be "missing" from the log.
- Added bus label to message and signal pickers.
- Fix for crasher when editing enum values in the signal list.
- Minor UI fixes and improvements for iPad
- Fix for multiplexer field (it is now an integer rather than a decimal)
- Other minor crash fixes and enhancements

Great app for viewing key car data

Finally an app that shows Tesla data for iOS! Information such as motor power, battery cell temps and max regen are now at my fingertips. A must have for iOS Tesla users.

Extremely powerful and configurable

This is the ultimate data viewing app for Tesla, and the only one where you can update and add your own signals without an need to update the app. In fact you can load in a database and use with any CAN device. Gauges have several well thought out options so you can have different styles on screen simultaneously. Ive been using this to produce a series of YouTube videos deep diving into the signals in my Model 3 and how it’s various systems react to different situations.
