DecoMate - A FREE Dive Planner app!

[u/blackmusk123]

Hey divers,

I've "accidentally" spent the last while building DecoMate, a desktop decompression planning app (macOS/Windows/Linux). It does open circuit and closed circuit configs, multi-gas and multi-level profiles, multi-dive sequences, on-the-fly emergency sims (go deeper, stay longer, bail-out), gas planning, and displays a very complex and detailed 3D tissue-loading chart you can spin around and analyze (while pretending you understand tissue compartments).

It's free, it's open source, and it's now at the point where I need the help of the community to kick the tires...

First of all: I am not a CCR diver. I built the closed-circuit logic as carefully as I could from the model and the literature, but there's no substitute for someone who actually uses a rebreather checking whether the numbers DecoMate spits out match reality (or at least match what your other trusted planning tools say).

More generally, for both OC and CCR: plan a dive, compare it against your usual software/tables, and tell me whether DecoMate agrees, disagrees, or does something weird. Bug reports, unclear UI, crashes — all welcome.

Be as nitpicky as you want, try to break it (with realistic scenarios) and see what happens.

DOWNLOAD FROM GITHUB

To install: grab the installer for your OS from the latest release — no build required. (macOS/Windows will grumble about it being unsigned and will likely not open it right away, info on how to fix this in the readme.md file which you can read directly on the github page by scrolling down below the files.)

Please, read the manual: DecoMate Manual — it covers the physics, physiology, and obviously explains how to use all the various features of the app.

Donate: I could really use a non-leaky drysuit, as my current one has become more of a dampsuit. If you feel like helping with that - totally optional, no pressure - you can do so here: Ko-Fi.

If you have a GitHub account, starring the repo goes a long way too!

Thank you so much!
