Reciprocity Timer

Make the ability to add and modify data. For example, data on Fomapan 100 is not quite correct.

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.

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.

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??

You pay $1.99 only to find out you need to upgrade for $9.99 to use all the features.

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.

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.

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.

It will not boot up. Tried rebooting the phone and no help. I can’t even review this app. It does not work.

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.
