### 2/5 — Not really worth paying for

*2023-02-04, version 4.0.0*

Questions don’t really match the SSI open water course, random quizzes and completed tests show up in the history. Not really worth buying.

### 5/5 — Fantastic resource.

*2022-12-01, version 4.0.0*

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.

### 5/5 — Great review

*2022-09-18, version 4.0.0*

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

### 3/5 — Not a bad refresher

*2019-06-07, version 3.0.2*

Not a bad app to refresh diving theory, tables etc. the only problem was, even though you select metres in preferences, half the text is still in feet. Apart from that, not too bad

### 5/5 — Great

*2019-04-29, version 3.0.2*

Awesome way to review and study

### 5/5 — Very good for starter and intermediate

*2019-02-01, version 3.0.1*

If the developers read this, please include an advanced version.  There used to be an app that tested you on figuring out SAC rates, dissimilar tank sizes/fills, how to calculate lift needed on object- for both salt and fresh water.  This is great for divemasters and tech diver training.  Also tank expansion in F or C for set temp change, both in bar and in psi.  The app i used never got updated and is long gone  ( plus had some errors ). It would be great if you can fill this niche.  Also turn pressure of 2 divers with different sac rates with dissimilar  tank sizes.  Knowing how to figure this out could save lives.

### 5/5 — Great App for confirming / refreshing knowledge

*2018-06-25, version 2.1.2*

I enjoy using this App, it achieves its objective - well done!  Great fun using the dive tables again - the dive computers do make us lazy. In my view it’s still really important to remember how to properly use the tables.

### 5/5 — Outstanding Content!

*2017-08-04, version 2.0.2*

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!

### 2/5 — Crashes

*2017-07-01, version 2.0.2*

App crashes a lot and has a lot of bugs.

### 3/5 — Crashes frequently

*2017-05-13, version 2.0.2*

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.
