User reviews

Not for beginners

Definitely not a friendly app for beginners. No instructions for use!

Response from developer

Hi, could you please contact us so we could learn more and improve the app.

Best dive app on the market

This app has replaced all the others I use. Simple, functional, and powerful! Well worth the money. I emailed the developers a few weeks ago about a tool I would like to see added and it came out on the next update - now that is service!

Don’t Bother...sneaky expensive

Dive planning (the only useful part) is an in-app purchase. I don’t mind paying but If the developer isn’t honest enough to disclose costs before download i’m not sure I’d trust them to plan my dives. MultiDeco is pricy, but at least you know upfront.

Response from developer

Thank you for your comment. Could you please tell us in which step you did not know the price so we can change that.

Vague value proposition

What exactly is the appeal of this app, aside from a (questionably) nice graphic design? Multi deco, the gold standard in decompression planning, provides same or better functionality, more transparent and flexible models (most important), and it is less expensive in the long run. The developers of this app have yet to convince me they have a better mousetrap.

Fantastic software

I didn’t understand why other tools were so well regarded. These types of tools are hard to create because they require deep knowledge of software development and technical diving. These folks nailed it. An absolute pleasure to use.
