With this tool you can calculate your exposure and needed adjustment for development. It uses zone system theory originally invented by Ansel Adams and Fred Archer. First decide zone of your shadows and measure the shadows. Then device highlight zone and measure the highlights. Measure these with the film ISO you are going to use. You also need to decide shutter speed in beforehand. The app calculates exposure aperture for you and also tells if you need to shorten (N+..) or expand (N-..) your development time. You will get best results with a spot light meter but mobile apps will probably do fine.

Verdict
The clearest difference is review sentiment: Zone Tool at 100% against ImmichTV's 20%. Zone Tool also leads on in-app purchases (none vs 1) and ratings volume (6 vs 1). ImmichTV's advantage is rating (5.0 vs 2.8) and update cadence (every 4 weeks vs every 38 months). On ads and monetization model there is nothing between them.

Zone Tool costs $0.99 and ImmichTV $2.99 up front. ImmichTV sells 1 in-app purchase, starting at $0.99 per month. Zone Tool asks for nothing beyond the download.
ImmichTV holds the better App Store score, 5.0 against 2.8. That said, the two scores are not equally well evidenced: Zone Tool has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Zone Tool's written reviews are positive against 20% of ImmichTV's, so the app with the better star average is not the one people write more warmly about.
Zone Tool ships an update every 38 months, ImmichTV every 4 weeks. The most recent releases landed on September 21, 2026 and October 8, 2026 respectively.
