v3.0: The Development Timer is rebuilt by step. Steps follow the process order. Set duration, temperature, and agitation on each step, and write a bath-change note when you need one. The same bath can be added again. The order can be changed. Alerts: Background alerts match the on-screen timer. While the timer waits between steps for you to pour off and continue, completion alerts for later steps do not sound early. After a pause, the next agitation alert is recalculated from the time you resume. Year in review: In Records, you can make the tall image "My darkroom year." It shows sessions by month, days developing, the films and developers you use most, and your density feedback. Saving to Photos requires permission to add photos. That permission is only for this image. Backup: Sessions, favorites, and chemicals stay. This version can import backups from earlier versions. A backup exported from this version cannot be opened by an earlier version. If you still need a file the old version can read, export it before you update.

DevGlass 2.5 — Cleaner data, rock-solid timing, and a post-dev feedback loop • Chart data overhaul: corrected long push times that were wrongly scaled down, for more trustworthy recipes • Timer reliability: fixed Live Activity crashes, missed background steps, agitation phase drift, and lost notifications; resume after the app is killed • Feedback loop: rate negatives as thin / normal / dense after drying or scanning, then start the next run with your personal time • Safer dilution: Jobo inversion vs rotary volumes labeled separately; HC-110 letter codes and non-1+N ratios; minimum concentrate warnings • Chart UX: friendlier search (d76, trix, hc110…); brands fully expanded with A–Z index; “Recently used” times on the home chart • Timer UI: start/pause and skip stay in fixed slots to avoid accidental reset; next agitation countdown under the ring • Darkroom fullscreen brightness control; system brightness restores on exit or when backgrounded • Records & backup: new logs default to 1 roll; backup format upgraded with legacy import support; safer database upgrades
