## Most critical reviews (10 lowest-rated)

### 1/5 — Uhhhh...

*2019-10-15*

Nothing shows up on the reciprocity tab rendering this app useless for me even though I just paid for it... Using 13.1.2.

**Developer response:** The latest version of Reciprocity Plus (1.11.2)  features compatibility with the dark mode of iOS 13.

### 3/5 — Good but…

*2025-11-07*

It is absolutely great for its fundamental purpose, calculating reciprocity departure time. 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.

**Developer response:** Tap on the heart icon to add a film as a favorite,  tap again on that icon to remove from the favorite list (like the Music app).

### 3/5 — no funciona bien

*2019-10-13, version 1.11.1*

es una aplicación estupenda, pero el otro dia la fui a utilizar y ya no funciona correctamente.

### 5/5 — Must have

*2024-10-12*

In the Analog profession

### 5/5 — Très pratique

*2022-07-03*

Application simple mais efficace pour calculer les corrections de temps de pose lors de l'utilisation de filtres et d'expositions longues (effet Schwarzschild)

### 5/5 — Works, Works, Works!!

*2021-01-27*

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.

### 5/5 — Works great

*2020-06-07*

The app is really helpful to look up reciprocity failures on the go. The design is somewhat old-school but doesn‘t really hurt usability.

### 5/5 — Can’t see the text in the Dark Mode

*2019-10-23*

When I switch to the dark mode, the background turning into the black, but the text is still black.

**Developer response:** The latest version of Reciprocity Plus (1.11.2)  features compatibility with the dark mode of iOS 13.

### 5/5 — Love This App

*2019-04-27*

So handy and works well. Hope future updates include a bellows factor calculator for large format, view camera shooters.

**Developer response:** Thank you for your suggestion. We will look on how to include bellow factor. Please note that pinhole assist, another app we produce has complete support for bellow factor.

### 5/5 — Magnífica

*2014-12-30, version 1.3*

Indispensable para gestionar el fallo de reciprocidad de las películas fotográficas. 
Además, permite calcular instantáneamente los incrementos de exposición provocados por la adición de filtros.
