You can use the original, free app "Soul EV Spy - Lite" instead, if you do not want to pay for this app. Less data values from the car is read by the free "Lite" version, and it doesn't save data in .csv-files.
Soul EV Spy lets the owner of a Kia or Hyundai electric car view detailed information about their electric car's main battery, by plugging an inexpensive KW902 ELM-327 v1.5 Bluetooth OBDII adapter into the standard OBDII port of the car. The app cannot modify any settings in the car. The app only reads data from the car, via the OBD-II dongle, displaying and saving data files. It does not write settings to the car.

Konnwei KW902 ELM-327 v1.5 Bluetooth adapters are available for around $10-$20, and one is required before Kia Soul EV Spy can extract data from your car.

Many of the cheap ELM327 OBDII Bluetooth adapters from Asia does not work with the app, and often report themselves to be version v2.1. The only one currently recommended is the Bluetooth Konnwei KW902 v1.5, because it supports all the needed ELM commands to communicate with the car systems, and it is the OBD-adapter that works best, of the adapters I have tested.

The app requests access to the device file system. If you grant access, the app will store data in files in the Download catalog on the device, for later replay in the app, or for the user to use in other apps, e.g. a spreadsheet for data analysis.
This app requests access to phone location, in order to request locations of nearby quick-chargers, and to calculate car speed.
