## Description

Traceable recipes to repeatable results: update temperature to correct development time, follow agitation and pour cues on Lock Screen and Dynamic Island, save every run.

Agitation is a film development timer and record keeper for black-and-white darkroom work.

Choose a film, developer, dilution, ISO, and temperature, then run a clear step-by-step timer for your development process. Save sessions with notes, temperatures, and sample photos so you can compare results and repeat working setups.

The free version includes 20 common official recipes, custom manual recipes, 3 complete development runs, 5 saved records, 1 sample photo per record, 2 temperature updates per run, and 1 reusable setup.

Agitation Premium removes these limits. New users can start with an eligible 7-day free trial through the App Store, subscribe monthly or yearly, or choose a one-time lifetime unlock.

Premium includes:

- Complete official film and developer database
- Unlimited guided development runs and temperature updates
- More saved records, sample photos, and reusable setups
- Ongoing data corrections and app updates

Monthly and yearly subscriptions renew automatically unless canceled in your App Store account before the renewal date. Trial eligibility is managed by Apple and is usually available once per subscription group. The lifetime option is a one-time purchase.
