Manage your film photography from start to finish!
Initial purchase allows you to calculate reciprocity for all the films included by selecting an observed exposure time. This non-pro version is suitable for people who just need to calculate an exposure that includes reciprocity adjustments for their selected film. It will suit many users who don't require note keeping or a camera database etc. It's most suitable if you are new to film.
More advanced users will want to upgrade after their initial purchase to the pro version.
This will unlock all the additional features of the Note and Camera 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".

Very poorly designed app
Paid $1.99 for an app that doesn’t allow one to change most of the settings and while the instructions state that an upgrade to the pro version can be purchased within the app, I’m unable to find a link/button within the app to do so. Paying for apps is something i am happy to do, knowing that it normally supports better products, but either charge the full price up front, for a fully working app or make certain that the upgrade link is available within the app as mentioned in the manual.
Has changed the game for me
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.
Clever but text is way too tiny
Seems like a useful app, but I may never really know. The text on screen is way too tiny to read. Does the designer intend for us to use a lupe??
Bait and Switch
You pay $1.99 only to find out you need to upgrade for $9.99 to use all the features.
Was good, not so much now
Keeps crashing or deleting custom settings. Tried contacting developer and got no response. UPDATE: app is working great now after a conversation with the developer. Sent him screen recordings and data to help him figure it out. App update was done in a few hours, approved by Apple and downloaded to my phone a couple hours later. It’s already helped me. Cheers.
Good idea.. bad implementation
Have you guys actually used this app? Or did you just chuck it onto the App Store without even testing it?? Because that’s what it seems like for sure. I have yet to use a feature that doesn’t have bugs; if it even works at all. Did you notice the keyboard won’t minimize unless you have a particular text box in focus? Or that you have to select each film holder you create as you add them else the entire list will peace out into another dimension when you do select one? I could go on for an hour but I’m not your beta tester.. I’m unfortunately your customer. You need to take a serious look at your process.
Film Holder Glitchy
App closes when choosing a custom film holder with Pro version. Reinstalled app and still doesn’t work. I tried contacting developer, but I don’t Facebook. Otherwise, app is very helpful.
Do not buy this app
It will not boot up. Tried rebooting the phone and no help.
I can’t even review this app. It does not work.
100% inaccurate
Awesome idea but is totally wrong. Being able to compound multiple filters, bellows, compensation and reciprocity is fantastic. Except the reciprocity calculations for FP4+ is totally wrong. Even simple calculations do not match up with published data. I tried to contact the developer with an example discrepancy and questions and they never responded. I won’t continue using the app because I can’t rely on it.
Complete Rip-off
Do not waste a dime. 95% of the features are not available without the pro version. It’s $2 so I’m not losing my mind but just warning you to pass on this app.
