HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (0.6 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

★★★★★Dec 1, 2022
Fantastic resource.

I’ve used this app for years, more than a decade probably. I go long spells between dives and regularly need to refresh my scuba knowledge. I’ve always been disappointed by how guarded the big Scuba organizations are with their educational information. I understand that they need to make some money but it seems counterintuitive to hide basic scuba safety skills behind a paywall. bravo for this app.

★★★★★Sep 18, 2022
Great review

I have enjoyed scuba exam for quite a while. I appreciate the updates and the explanations it’s a great way to study and review. Thank you scuba exam for a great product

★★★★★Apr 29, 2019
Great

Awesome way to review and study

★★★★★Aug 4, 2017
Outstanding Content!

The content in this app is great for newbies or seasoned divers. All the custom settings for each quiz are really neat too. Being able to choose which agency you are certified with is awesome. I think one of the coolest things is the explanations to each question and a large theory section for even more knowledge. Awesome app!

★★★★★Jul 1, 2017
Crashes

App crashes a lot and has a lot of bugs.

★★★★★May 13, 2017
Crashes frequently

The questions seem good, at least as far as I've been able to proceed. I get quite a bit of freezing or crashing with this app (the paid version) on iPhone.
