There is a list of many many film types, with provision to save a certain number of those his favorites. However, and here is the butt, there appears to be no way to remove a favorite from the favorite list. This is a real bummer. -- Lkrndu, 2025-11-07 ### ***** "Works, Works, Works!!" Only downside is I wish it added more film options. Like Cinestill 800T. There is no official data for it but through experimentation it can be added. Lomo400 follows the same guideline as Portra 400 but there is no portra 800 for example. -- newmanix, 2021-01-27 ### *---- "Uhhhh..." Nothing shows up on the reciprocity tab rendering this app useless for me even though I just paid for it... Using 13.1.2. -- littlebesos, 2019-10-15 ### ***** "Love This App" So handy and works well. Hope future updates include a bellows factor calculator for large format, view camera shooters. -- JPCinPHX, 2019-04-27 [View all Reciprocity Plus reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Reciprocity Plus Discovered Keywords -
