It's important to remember that while scuba diving, it is always recommended to double check your calculations with reference to the relevant diver tables.

Verdict
The clearest difference is in-app purchases: MaxOpDepth at none against Easy Deco's 3. MaxOpDepth also leads on device support (4 vs 2) and iOS requirement (13.0 vs 16.3). Easy Deco's advantage is update cadence (every 2 months vs every 16 months). On price and ads there is nothing between them.
