iDeco was a freebe and was already a full function deco program for both OC & CCR.... The new Pro version is worth the upgrade. Better interface, easier to use, a few more features, and once again spot on. As a cash contributor to iDeco, I could have gotten this for free, but elected to part with the minimal fee Brock is charging here... He put a ton of time into this program, and it was time well spent. This does everything programs do costing five or six times as much. The blending function works very smoothly too.... I use it for CCR as do many other iPhone CCR divers... Never heard anything but very positive comments.

I had hoped to see some extra features, but besides a slightly different UI and finally having more options configurable inside the app (although now they seem split between iphone settings and app, which seems odd), there's not much difference between this and the free version. I gave iDeco 5 stars, but I can only give this 3, simply just for the lack of extra features for the price.

Good job

So many new features in pro that it's worth the money. Other apps that cost much more are harder to use than ideco. I use it for CCR dives and it makes my dive planning so much easier. From gas needed to bailout. Even has cave bailout built in. And if that's not enough it can help u determine the right mix and amour needed for dive planning. Good valued app. and great tool....thanks for creating this one.

Great app! Really like the new features.

Beautifully simple. The world of scuba is notoriously expensive, 8 dollars is a steal, thank you Brock!

Brock Brinkerhoff has done it again... delivering an excellent product, with an easy interface. Undoubtedly the finest deco software on the market. Get yourself an iPod Touch or iPhone. Its cheaper to get the iPhone than buy any other software out there!

Good update, Brock. I like the icons/toggles at the bottom of the display, the ability to change gradient factors within the app, and the text formatting for emailed plans. Looking forward to the VPM and 1:1 implementation.

There still are a couple annoyances in this version, but it's a lot more convenient to use than a laptop or pen&paper!

The program was very easy to use. All you need to do is add the gas you need and vola. Also it has the option for single and double tanks too. A great tool for scuba divers doing recreational or technical diving.
