The inability to fine tune stop settings makes the app pretty much useless. ### 2/5 — Not enough *2018-10-28, version 1.4.2* For a large company like Lee, I would expect for this app to be able to calculate when you stack filters since that is what a lot of us do to get the correct results. ### 3/5 — Could be better *2022-11-13* It is simple calculator with timer and nothing wrong about it but it could be better. It doesn't make sense to take exposures beyond 30s with digital. Anything above that can be averaged in post without additional sensor noise. Film however can be exposed for long time. It would be nice if we could add reciprocity failure factor, or even better if there were preconfigured film options. ### 4/5 — Really intuitive *2024-06-08* Great application that is very easy to understand. I wish instead of 3 bottons for 6/10/15 stops it had a similar dial to adjust to any stop between 2-15 as it would add more versatility to an already great application. ### 4/5 — Simple to use *2018-07-27, version 1.4.2* Great little app, only does one thing but it does it well. It’s an elegant design, the simple ones always are. One future feature request. Allow the user to enter the number of stops manually, not just via buttons. Keep the shortcuts for the Little, Big and Super Stoppers for a quick entry. Can you add an Watch app, please? ### 4/5 — Elegant *2017-08-24, version 1.4* A simple app that works, nothing flashy, simple to use, with a timer to make life a little easier. BRILLIANT ### 4/5 — Helpfull App *2016-04-30, version 1.0* Using any Lee stopper takes a little more time and effort to use and I find this app helps a treat. It's much easier to use and see the app than look at the exposure card that comes with the filter. Really works for me. ### 5/5 — Awesome! *2020-05-29* I just bought the PolarPro filters and was surprised that there wasn’t an app to help go along with the filters. So I downloaded this one and it’s great! ### 5/5 — Excellent *2019-05-30, version 1.4.2* Exactly what I was looking for 👍👍 ### 5/5 — Simplicity is great *2018-04-02* I have always admire people who could simplify things. By this standard the author is great ## Most praised reviews (7 highest-rated) ### 5/5 — Extremely Helpful *2017-10-27* Quite the handy app when using ND filters. Even works with both my Cokin 10 & 6 stop filters. ### 5/5 — Simple to use *2017-06-22, version 1.4* Great app, really simple to use and I like the inclusion of the timer. Exposures seem to be pretty much spot on using the suggested exposure time. ### 5/5 — great design *2017-05-31* nice simple design that is super easy to use. thanks ### 5/5 — Does the job and more *2017-05-30* Great app, simple to use interface that makes the process second nature. Having the extra content and links from the menu was unexpected and a wonderful surprise. A great feature to add would be a kelvin converter to help adjust for the blue cast on the range of stoppers, even though kelvin can be easily corrected in post, it would be great to have a quick realtime view of a more natural WB during shooting. ### 5/5 — Brilliant *2017-05-14* Great simple app for my lee stoppers :D ### 5/5 — Simple to use, simple to understand *2016-07-22, version 1.4* The app does a very simple thing (which admittedly it is fairly easy to do in your head) but it is good for confirmation and the timer is a nice touch. ### 5/5 — Incredibly simple *2016-05-25* Wonderfully simple app for those with a 6, 10 or 15 stop filter. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
