how it came to be

I got certified in 2016.
Then I filled the logbook.

Once my paper logbook was full, I went looking for a digital replacement. What I found sent me down a five-year detour.

The app stores were a wasteland

Clunky interfaces, missing features. Chatting with fellow divers on trips, it seemed everyone either reluctantly settled for the PADI or SSI apps — the path of least resistance, but still leaving much to be desired — or gave up logging completely.

That part I could live with. A logbook is a logbook. What actually wore me down was everything that happened before the trip.

before every trip

Logbook archaeology

As I prepped for dive adventures around the globe, I found myself caught in the same time-consuming cycle before each one.

  1. What do I pack?

    Deciphering what to bring based on water temperature — cue frantic logbook flipping, trying to recall similar dives.

  2. How much lead?

    Calculating weight belt requirements based on wetsuit thickness. More logbook acrobatics, with no real clue if past weights were spot-on or way off.

    ↳ first-dive guesswork and splashing ensues

  3. This form again?

    Filling out repetitive paperwork that felt like déjà vu every single time.

Poor Knights 22 m 17° 10 lb
Similan #4 24 m 8? 9?
Blue Hole 30 m 26° too much
Somewhere in here is the answer.

So I built the thing I wanted

I decided to create a dive app that would streamline these processes and save me from endless research and logbook archaeology. Something that eliminated all my dive-prep ruminations and actually extracted data and value from these logbooks.

Enter SCUBAzen:

  • A sleek, user-friendly digital dive logbook
  • Wetsuit thickness estimator, filtering previous dives at similar temperatures
  • Weight calculator for your belt, considering equipment and body type
  • Auto-generated dive shop paperwork in PDF format
  • Customized packing list based on owned gear and rental needs

…with more features in development

This is the part worth the trouble.
None of the rest of it is.
