Reciprocity Timer

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

Really poor experience: if you have a free app and charge for the pro version, fair enough, but to charge for an app and then charge another $15 to actually make it useful is REALLY deceptive practise. What’s the point in this app if you can’t choose your camera ffs?

Paid for the app only to find out you don’t get every thing unless you pay more money. GFY!

No sure why this is an app you have to pay for to get restricted use of, only to find once you’ve paid that it’s going to cost another $15 for the app to work correctly and calculate correctly. Would be good if you could ad your focal length camera type film type etc to get a correct calculation but that is only in the pro version so ideally I’ve paid for a totally useless app that will only do what it specifies it will do if I’m prepared to pay more. I like a refund as I honestly feel ripped off!!

Not sure why this app doesn’t have more good reviews. Best app ever for anybody using film.

Before this app came out I used to refer to the manufactures instructions for each kind of film used and they do not have the additional information like filter compensation etc. I find this app extremely useful and have everything calculated for you including long exposures using film. What I also love about this app is the auto note and the feature to take pictures as attachments and the zones editor is a great feature recording what your thoughts were at that time do not have to remember everything thanks for the app made my photography easy.

Hi Guys - another request! I was using the app with PAN-F in the Hasselblad a few days ago, down the coast, to get some nice seascapes, and the exposure time ran to about eight minutes with the 10-stop ND filter. Can you set the app to suspend the iPod auto-lock function to keep the screen and the sound alive while the timer is ticking? That would be a real help. Other than that, I'm really enjoying the app and putting it to good use to help me get some great photos (when I manage to do my part right!). The reciprocity times for HP5 and PAN-F seem to be pretty close to spot-on. Thanks again - cheers! Chris.

App davvero molto utile per calcolare i tempi effettivi del difetto di reciprocità...mancano molte pellicole ancora e spesso si blocca su iPhone 6S plus aggiornate x favore....

Perfect for serious film photographers.

You pay for the app just to find out it is crippled. If you want to take notes and add more films you are asked to pay for the full app at an insanely high price of €10,99 just for these features. Seriously? You may think you don't need to add more films, well, it's actually possible that you do since the list of films that come with the app is small, for instance there are no Adox 20 cms II and Rollei 400 infrared which I shoot. Look elsewhere, this is not the type of business to support.
