Works with CATS

It does work well with the CATS program. The subscription payment is much too pricey for an app that is likely quite stable now. The ad revenue for free access isn’t a bad, but it’s not like it’s candy crush. A 30 second advertisement EVERY 24 hour period so I can check work is AGGRESSIVE. I’d rather pay $30 or $40 up front and be done with it. Update - the now 60 second ad freezes the app up and I’ve switch to the competing app that has a ONE-TIME payment instead of this greedy subscription based service.

Great app for fkeys

Great app, helps a lot having fkeys on the phone.
Will be cool if i can actually link fkeys in to my iPhones actual keyboard somehow and use it in safari or other browsers, 🤪
Even for a monthly fee..

Great app!

App works flawlessly for my application. I view a short commercial or play a random game for a few seconds. Not an issue what’s so ever. Great app! Highly recommend.

Longer use Review

This app does everything you need to do with Pressing F5, F3, F11… my trial ran out, I haven’t paid but the 5 second ads once a day are a small price to pay to keep this free. If you have a new iPhone and can’t get your old Fkeys app, this is the one to get!
