iTheory vs. Driving Instructor24 Apps

Hi folks,
Looking for driving theory exam apps, I see two major options:
1. iTheory from Swift Management AG: https://play.google.com/store/apps/details?id=ch.swift.itheorieasa&hl=en&gl=US
2. Driving School Theory 2024 from fahrlehrer24.ch: https://play.google.com/store/apps/details?id=com.tigerlab.fahrlehrer

Both are priced almost the same + claim to have the same features.

Anyone who tried either, how was your experience? Do folks prefer one over the other?

Thanks!
