User reviews

Free for 3G

App is free for 3G but is needs a subscription to limit all other data

Good for seafarers

I don't understand the low reviews. The app does what it says. It saves data and works well for starlink.

Greedy C**t

A week into me downloading this app and using it this greedy fool decides to put a paywall between me and the majority of the app functions. I guess I’m the only user or one of a very small few who have a specific need for this app. Instead of putting up ads or something this 👃 decides to lock off the entire app behind a paywall.

Not limiting the speed

Does not work, high speed is still used despite app is set at low speed. It exhausted my daily data faster.
