## What is Umbrio?

Umbrio is the precision darkroom print timer built for analog photographers who demand reliability in the dark. Set any exposure from 1 to 999 seconds, recall saved presets instantly, and never lose a print to a missed countdown. No account, no network, no distractions — just a fast, accurate timer that works the moment you open it.

Upgrade to Pro to unlock the full toolkit: guided test strip sequences that walk you through each incremental exposure step-by-step, an f-stop calculator that instantly converts any stop adjustment to the correct new exposure time, and unlimited custom preset slots so every paper, enlarger, and workflow has its own saved time.

Umbrio is fully local-first — your data never leaves your device. There are no subscriptions, no ads, and no accounts. One app, one purpose, done right.
