Five Nights At Fredddys Tips ,

It’s fine if you have a buck worth spending.

I recently downloaded this app because I didn’t have a spare protractor on me. However, this isn’t really useful unless you purchase the camera feature for $0.99. I have it, and it works good, but it would definitely get a higher review if this feature was for free, as this seems like it could definitely be more useful for people who don’t want to spend money on an app when they don’t have a protractor handy. Overall it’s fine, but if it was all for free this app would get a five star.

Completely Worthless when Free

Genuinely disappointing. I have never seen an app go through so many measures to force you to buy the upgraded version, even apps that don’t offer a free version do less to convince you to pay them. It’s defaulted in radians and if you try to use degrees it will prompt you to buy premium. Just about every feature is a premium feature, meaning unless you’re forking over the money for premium it’s just a radian protractor. Even just trying to use the radian protractor will periodically prompt you every set amount of seconds spent moving the measuring slider about not owning premium and lock you out of touching anything in the app for 12 seconds. It’s not even an ad, it’s just telling you to buy premium. I think I’d be less annoyed by incessant ads, banners, etc than by someone’s intently programmed measures to inconvenience anyone using the free version without any intent of at least gaining money by showing ad slots or anything of the sort.

15 Second Time Out

This is just a protractor, you must upgrade for other features. BUT even the protractor “times out” after a few seconds then you must wait 10 seconds before it resets and you can use it again. It is basically forcing you to upgrade to make it usable. I was going to buy the full version until I played with the protractor and saw they designed the app to force in-app purchases, thus rendering the free tool useless. It’s a shady gimmick in my opinion and I’m uninstalling now. They just lost a customer since I was willing to buy the upgrade for the other cool tools they supposedly offer.
