Pelotrak is still in testing. However, it is easy to join while it’s still being developed:
Download and open Apple’s TestFlight: https://apps.apple.com/us/app/testflight/id899247664
Sign up for the Pelotrak beta app: http://bit.ly/pltrkios
Once signed up, Apple will send an email with a code (check the spam folder if it doesn’t arrive).
Open TestFlight and click on “redeem” in the top right corner, enter the code from the email.
This allows you to install Pelotrak.
Install Pelotrak directly from the Google Play Store: https://bit.ly/pltrkandroid
