Manage your film photography from start to finish!  Reciprocity Timer has 2 Version - the "Standard" Version does NOT include advanced features but can be used to calculate reciprocity on a range of common films. The "Pro" Version is available for an additional $9.99 USD (via in-app-purchase) unlocks a range of advanced features. The initial purchase price allows you to calculate reciprocity for all the films included by selecting an observed exposure time. This $1.99 US non-pro version is suitable for people who just need to calculate an exposure that includes reciprocity adjustments for commonly used films. It will suit many users who don't require or need to upgrade to the pro version for features like note keeping or a camera database etc. It's most suitable if you are new to film. More advanced film users and photographers may want to pay to upgrade after their initial purchase to the pro version. If you use a pro-feature you'll be prompted to upgrade for an additional $9.99 US. This will unlock all the additional features including the Zone Editor, Note, Camera and Film Holder database as well as custom films and filters. There is no need to upgrade if you just want to calculate and time reciprocity for a particular film and you always use the same camera. The app includes in-app purchase to unlock pro features including a note-keeping feature, the ability to add custom films and the ability to select often used film stock as favorites. Once you upgrade then the one app does it all - notes, filters, exposure calculations, custom films, zone system editor, film holder management as well as the reciprocity math! A comprehensive film reciprocity calculator for photographers. Select a film type and metered exposure time - the calculator will provide a reciprocity compensated exposure time. The app includes an exposure timer so you can time your long exposures. You can also use a slider to adjust exposure when you have filters attached. The app supports a wide range of film stocks and allows the user to add various common exposure filters such as NDs and Polarizers. Keep detailed notes and share them. Share your adjusted exposure times with colleagues. This app makes film photography a breeze. You may need to setup Reciprocity Timer in Settings -> Notification Center to ensure the app's timer can notify you when exposures are ending and your device is asleep. Watch companion app now included. To install the app use the Apple Watch App on your phone. Ensure your watch and phone are paired an unlocked and scroll down the list of available apps to Reciprocity Timer. Select Install. You can also turn on "Automatically Install Apps".}

I’ve been using the app for a few years now and it has been very useful. Two improvements I recommend: To be able to lock the film type, as it’s easy to change accidentally, and the ability to select more than one filter without having to return to the main display between each selection.

Not much choice of film stocks listed. I was hoping ultramax 400 would be in here.

Cannot change the camera without having the pro version which is an additional 11€. I would suggest to find something else….

I would like to report an issue with Reciprocity Timer App. After the update to version 3.9 the app keeps crashing and closing on my iPhone (14 Pro Max, ISO 17.6.1). I use Reciprocity Timer to record my photo data, and it is very useful. I hope this issue is resolved as soon as possible.

The ability to add notes with an image is the strongest point of the app. Version 3.9 BROKE notes, you can open old notes but adding a new note will cause the app to crash EVERY TIME. Please fix this, thank you.

Not many film stocks. Just pushes you to pay more for a ‘pro’ version. Can’t get your money back. Avoid.

As all of my lenses have speeds that are NOT true to their stated times, that had cause many years of frustration in attempts to get good exposures. I had purchased a shutter speed timer, and hand written the speed averages for each, but attempting to then mentally calculate exposure reciprocity? It was a nightmare. Then I hear of “Reciprocity Timer”. Now with the App enhancement of being able to enter my own shutter speeds, I have consistently taken good exposure photos time and time again.

The app doesn’t provide a wider variety of films to select.
