Get comfortable and switch to airplane mode bc App won’t run in the background;

I’m in the middle of a dive course and have to complete the online portion before moving on to the open water dives to get my cert. a friend told me to use the App. What he forgot to mention is that this app does not run in the background so if you answer a text, Check email or even get a phone call, you have to start your download over. Based on your connectivity, the initial download takes forever; its even more irritating when you only have 20MB to go and someone calls you. Now your back at square one. Most people learn to dive while on vacation so they are limited to hotel Wi-Fi or portable hotspots with very slow speeds. At least let this app run in the background so you can entertain yourself during the two hours waiting for a section to download.

Worked fine for me, and it got me on the way to open water certification

I was extremely hesitant to use this app with the negative reviews, but didn't have much of a choice since I don't have access to a desktop PC to take the course. I'm glad to report that it worked just fine for me using booth my iPhone and primarily my iPad. The layout of the material did take some getting used to initially, but it wasn't that hard to navigate. I definitely think they could tweak the layout to be more intuitive, but I wouldn't call this app unusable. Resizing text was frustrating at times as it scales oddly and requires some fidgeting to get it right. I agree with others that submitting results is a little wonky, but I never had any issues with results not posting. For each test submitted I received an email shortly thereafter confirming the results were logged.

Horrible app. Virtually useless.

Currently taking the Nitrox course and this app is virtually unusable on my iPhone X. The lesson plans show up in small odd constrained boxes. Don’t load. Are slow to flip when I try to go from portrait to land scape mode. The text acts like graphics in that I have to zoom in and then scroll from left to right to read it, because it doesn’t flow, but instead half the line is outside the margins of the box it’s contained in.

Unfortunately the desktop version isn’t much better. And all the text has scroll bars and boxes within the pages. Ugh. Just horrible all the way around.

Guess I’ll need to go back to a paper book next time. For what I paid I should not have these issues.
