Lacking updated UI

MultiDeco is an exercise in how long you can put off and delay updating the UI. Needs an overhaul plus integration with the desktop app to be worth this price.

Does most of what you want

2020 - Buyers be aware that the purchase of this program is not transferable across platforms (mobile or desktop ). If you want to use it on both, you have to buy the program twice. I spoke with Customer Service and they confirmed I would have to purchase twice however that bit of info is not readily found on their website.

Almost...

Its missing the ability to put both CCR and OC legs in the same dive plan (this option is available in the full Mac version). This is a very useful function for easily calculating and figuring out bailout gases for CCR. (The included bailout function isn't great).

This is functionality that they will hopefully add in the next version. Sticking with the "full size" version for now.

Good products, lazy developer

It's the only game in town, but the developer really needs a designer. It's still not formatted for the larger screens and overall the UI is pretty bad. One day someone with similar tech diving knowledge is going to come along with a really good UI and knock HHS off its throne. Lesson: never rest on your laurels. Always keep improving.

Needs an update for iphone8 Plus and ipads

I had written this review when I had iPhone 6 Plus and now using 8 Plus, still have issues with pull down truncating, MultiDeco configuration window does not scroll fully on the iPad so I can’t configure those options...

I hope you can fix this as it is my go to app for trimix dive planning.

Thanks!

On the iPhone 6 Plus, some of the display options are truncated, such as Equiv air depth, MOD, if you select Depth pull down, after 99, it shows 1…. making all the following display not readable. It seem that the pull down option area could be widened so you can show 3 digits, this appears in other areas of MultiDeco as well like P02 set so anything above 1.0 gets clipped to 1….

MultiDeco is very useful and you can still use it, but for an app that is $54.99 I hope that you keep MultiDeco up to date.

Thanks
