### 3/5 — Closing

*2020-06-06*

Closing when you try to send the plan

### 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.

### 3/5 — Antiquated algorithm but adequate...

*2015-12-17*

Still an antiquated algorithm with the addition of more rainbow farting unicorns. Limited but adequate for light to moderate technical dives. VPM would make this app a real winner and suited for more advanced mixed gas OC/CCR dives. Good for the money tho! V-Planner is still the better choice for the serious technical diver.

### 4/5 — Now works with iOS 9

*2015-10-17, version 3.0.0*

The app now works with iOS 9. 😃

### 4/5 — Pb avec iOS 9

*2015-10-06*

Plus de chiffrage de pourcentage des gazs depuis la mise à jour en iOS 9. À résoudre d'urgence!!! Sinon très bonne appli je m'en sert pour mes décos

### 2/5 — BUGGY!

*2015-07-01, version 1.3.0*

Useful, but too many bugs to bother listing. If you rely on it to cut tables (ehhhhh), make sure to double-check the work with a different app!

Needs an update really badly. Graphics not entirely compatible with current iOS. Rendering errors abound. 

I'm starting to suspect this app is "abandon-ware" sadly. Here's hoping I'm wrong.... :(

### 4/5 — excellent

*2015-04-28*

très complet excellent pour trimix et nitrox conf

### 3/5 — Seen better

*2015-03-22, version 1.3.0*

Decent app. Leaves a lot to be desired. Baltic is better.

### 4/5 — Application Support / Feedback

*2014-07-25*

The support links go to a website that doesn’t have anything but a splash page. Our diving group uses this program to plan dives, and we use the dive plan email feature to send dives to one another. 

One thing that’s missing from the email is the surface interval between dives.

### 3/5 — Good app with too glitches

*2013-11-08*

As general speaking the app do the job but with some considerations, for example when you plan a deco dive within the app and the dive plan throws you lets say a deco stop at 9m for 8 minutes and you set a leg at the same deep for 10 minutes the app dont recognize the extended level and still set the 9m for 8 minutes stop wich total time will be 18 minutes (extended level plus real deco stop) very diferent from the original 8 minutes or even 10 minutes level.

Also would be great to controll the ascent rate,  descent rate and sac more precisly . My real deco sac is under the minimum value on the app.

Delete waypoints or legs can be tricky because the app delete the waypoint but dont keep the info for the other wp instead the app overlap the info you are triying to delete with the next wp.

### 3/5 — nice but some bad bugs

*2013-09-26, version 1.2.5*

Cannot set SAC rate so gas planning is useless.

### 2/5 — Are closing

*2013-08-08*

Please update the app. This closing alone.

### 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

### 1/5 — No support, no instructions

*2016-11-05*

The app does not have any instructions on how to use. There is also no contact to the developer. The provided link just leads to an add for another app.
For a critical topic like planing a deco dive I need to be sure that I'm using the app correctly. This requires at leased a well documented manual.

In the current state the app is for this reason unusable.

### 1/5 — IOS9 Fail

*2015-10-05, version 1.3.0*

Please update this was a great app and use it a lot.

### 1/5 — Not working with recent OS updates

*2015-10-02, version 1.3.0*

This application has been very useful. However, since the last Apple OS updates, the application is not functioning correctly. It is not possible to select oxygen or helium content. The application is therefore unusable.

### 1/5 — Crash when change any settings

*2013-10-08*

iPhone 4, iOs 7.0.2 (latest)
Crash every time when trying change any settings.
Complete disaster….

### 1/5 — Programmfehler bei Settings

*2013-08-21*

Leider lassen sich die wichtigen Einstellungen wie Gaswechsel-Stopp Zeiten nicht verändern!! Ganz dringend ein Update liefern. So ist die App nur bedingt ihr Geld wert.

### 1/5 — Not worth it

*2013-06-06, version 1.2.5*

Not very happy with the app .. If you try to change the setting to suit ya plan it crashes .. Waste of money .. Wish I had listened to the other reviews .. It's a rip off and I want my money back .. Don't get the app it's pointless

### 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.

### 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!

### 5/5 — Super pratique !

*2017-01-29*

Tres bonne appli vraiment utile et efficace.

### 5/5 — Great app

*2014-05-24, version 1.3.0*

Worth
 every penny..

### 5/5 — Все круто!!!

*2014-03-23*

Нужна русская версия!!! Заранее спасибо!

### 5/5 — strong tool

*2013-10-29*

a great tool that was more than once helpul for planning my dives. Using the Weikamp OSTC MK2 as diving computer gave me the opportunity to compare both decompression data. So it's not simply a pure "trust" in ideco pro, it's a proofen thing.

### 5/5 — Great app as long as you know this!

*2013-08-07, version 1.2.5*

Previous reviews of the app crashing are correct BUT if you change the settings outside of the app in the iPhones settings panel then it will be fine. Go to Settings>iDecoPro and change them there.

### 5/5 — Awesome dive planner

*2013-02-17*

From simple air dives to complex trimix dives this has been our team's go-to dive planner since we first discovered it in 2009.  We used to use a desktop planner but when you're at the dive site or on the dive boat and things change you need a portal dive planner. 

We first discovered the need for this app when we were trimix diving off Pompano Beach and had to change our dive site due to currents. Rather than scrub the dive and go back to the campground to plan a new dive we were able to change our plan at the dock and had a great dive. 

Now we use it for every deco dive. It covers everything from gas management to oxygen exposure. We've been able to plan second dives while on the dive boat based on the results of the first dive allowing us to get the best bang for our buck on every boat trip. 

Thanks Brock for one of the most essential pieces of dive gear in our bags!
