Only free 10 seconds then 10sec ad, repeat

I’m guessing I found a stud in the 10 seconds the app allows you to scan followed by a 10 seconds ad to purchase their untimed/ad free app version. Even though it’s only $1.99, I’ll go with another app I found that’s free, accurate, and doesn’t have the annoying ad every 10 seconds for free

Scammer Does not work

No page inside the app. It does not work. Scammer, need refund. There is no way to get the refund

Pain to Use

Trial version is useless and constantly pushing to upgrade by blocking free trial usage. Horrible!

Useless

Can’t use the app for 5 seconds without being diverted to a paywall asking you to upgrade to premium.

Do not get

You only get to use for 5 seconds before you have to wait 10 seconds to use again. The constant pausing make this app unusable
