## Most critical reviews (2 lowest-rated)

### 1/5 — Not for U.S.

*2025-05-16, version 1.3.15*

Weight is in kg, pressure in bar.  Could not change it to pounds and psi

### 1/5 — A big miss

*2021-10-31, version 1.0.0*

Had very high hopes, but Poseidon just needs to stick to building regs. I ran a couple of CCR dives in the planner and the numbers are way off. A dive to 175’ for 20 minutes shows a total run time of 220 minutes?  That alone gives me 0 confidence in the app.  I’ll stick with IDeco Pro.
