## What is iDeco Pro?

A complete multiple dive / multi-level dive planner for the technical diver. Includes support for Open Circuit Diving as well as Closed Circuit Rebreathers (CCR). 

Includes decompression stops, gas usage, CNS tracking, OTU tracking, Surface Interval tracking and many other features. Currently implements the Buhlmann ZHL16/C with Erik Baker's GF algorithm. 

Open Circuit - Scuba : Supports Air to TriMix (any combination of O2/He/N2), with an unlimited number of decompression gases. Includes Thirds support for planning dives. 

Closed Circuit (CCR): Supports any O2/He/N2 combination for diluent. Automatically generates bailout plans based on entry of bailout gases. Features a Cave/Wreck bailout option for overhead environment bailouts and gas planning. 

Gas Fill/Mixer: Allows for filling of Air, Nitrox and Trimix via a simple, easy to use interface. 

All settings are configurable via the iPhone Settings. 

Supports US Imperial and Metric 

iDeco Pro vs. iDeco 
Pro has many features and improvements to make dive planning even easier. 

1) Fully revamped user experience

### 5/5 — Need Update

*2026-07-22*

Amazing and helpful app. Just stoped working with the latest update. I gave it a 5 star because in the past it is doing the job as intended. Please update it.

### 1/5 — Dont waste your money

*2025-12-16*

App is out of date, crashes a lot, doesnt work properly. Lost the money….

### 1/5 — Doesn’t work anymore

*2024-12-04*

This use to be great. Now it opens and immediately closes. 
Does not work at all. No support to contact

### 1/5 — App crashes as it opens

*2024-07-08, version 3.0.0*

Have seen it work on mates phones and it looks good. However, downloaded today and it crashes upon open and is unable to be used. Going back to MultiDeco

### 1/5 — crashing at startup

*2024-03-05*

The app is crashing at the start up, didn’t even open that once

### 3/5 — Closing

*2020-06-06*

Closing when you try to send the plan

### 5/5 — Great but needs an update

*2020-03-05*

Great app! But they need to update the screen size to fit the new iPhones (Iphone X and newer)

### 5/5 — Great dive planning software!

*2019-09-17*

The algorithm used in this app is fairly popular amongst other technical dive computers and their for fairly standardized. The user interface is what really makes this app rock! Everything that needs to be adjustable is and makes those adjustments incredibly easy. Better still is the price! You can’t normally touch software running this algorithm for this little cash. 

Weather your into technical deco diving or even basic recreational diving this app has something for you. The gas planning/consumption data is helpful in any dive planning scenario. 

I’ve bought VPM planner and other spendyer apps so I could run dive plans through multiple algorithms and HIGHLY prefer iDeco Pro’s user interface. When comparing deco schedules between the different algorithms, you’ll find there is very small subtle differences.

### 5/5 — Top Planungstool

*2017-11-18*

Sehr gutes Dekoprogramm! Übersichtlich, viele Funktionen, integrierten Gasmixer, tolle Bailoutberechnung für CCR. Ich nutze es zum planen von Trimix-CCR Tauchgängen!

### 4/5 — Good, Simple to Use

*2017-11-17*

The most recent NEDU data seem to indicate gradient factor based dive plans are more reliable than VPM and various bubble models that get you out of the water faster. Not having VPM is only really an issue if you need to match the plan to a dive computer that only offers VPM. You should also be checking technical dive plans against multiple sources, so I wouldn’t rely solely on a single app anyway. If this had settings for altitude diving and fresh water, I’d give 5 stars.

## Frequently asked questions about iDeco Pro

### What kind of diving does iDeco Pro support?

iDeco Pro is designed for technical diving and supports both open circuit scuba diving and closed-circuit rebreather (CCR) diving. It can plan dives using various gas mixes, including Air, Nitrox, and Trimix, with support for unlimited decompression gases.

### What are the key planning features of iDeco Pro?

The app calculates essential dive planning parameters such as decompression stops, gas usage, CNS and OTU tracking, and surface intervals. It implements the Buhlmann ZHL16/C algorithm with Erik Baker's GF algorithm and offers features like Thirds support for open circuit and automatic bailout plan generation for CCR.

### Can iDeco Pro help with gas mixing?

Yes, iDeco Pro includes a Gas Fill/Mixer feature that allows users to easily plan and mix custom gas blends for Air, Nitrox, and Trimix. It supports high-pressure mixing and allows you to manage a list of up to 50 frequently used gases for dive, deco, and bailout phases.

### Is iDeco Pro compatible with different units of measurement?

Yes, the application supports both US Imperial and Metric units of measurement, allowing divers to plan their dives according to their preferred system.

### What are the main improvements in iDeco Pro compared to previous versions?

iDeco Pro features a completely revamped user experience, with settings now adjustable directly within the app. It also introduces 'My Gases' for managing frequently used gases, a new runtime display, higher pressure support for mixing, and enhanced email support for plans.

## Version history (last 5 releases)

### 3.0.0 — 2015-10-16

This update from Apple will improve the functionality of this app. No new features are included.

2) Cleaned up UI and made it more efficient / faster

3) Fixed a handful of errors and memory leaks

4) All settings are now available within the app.  You no longer have to jump out of the app.

5) Fixed many, many problems with settings being changed and not sticking, etc, etc.

### 1.2.0 — 2010-04-15

Added new bailout planning options to specifically select the CCR bailout point.

Double tapping the dive leg will now allow you to select the bailout point for a dive.

### 1.1 — 2010-03-29

Completely revamped how multi-level diving is computed.  Prior release only allowed for each leg of a multi-level plan to be shallower than the first.  This version removes this limitation.

Also changed CCR bail-out planning for multi-level diving.  iDeco Pro no longer stops calculating at the first leg, and treats the last leg of a multi-level dive as the worst failure point.
