Miguel..... ### 5/5 — ND필터 사용시 유연한 어플이예요 *2020-09-18, version 3.0.0* ND필터 사용시 유용한 어플인것 같습니다 좋아요 잘쓰겠습니다^ ### 5/5 — Finally updated! *2020-08-27, version 3.0.0* Thanks you for creating such a convenient app for photographers all over the world! ### 5/5 — Great App! *2020-08-07, version 2.0* This app works very well as a long exposure calculator for novices in long exposure photography as well as professionals. The design of the app is great and everything is straight to the point. I am grateful for the lack of annoying advertisements. This is all I at least what I would expect in a paid app but for free. An alarm at the end of the timer would be nice, but I seldom use it. I use this app every time I take a daytime long exposure photo using a neutral density filter. It is far more efficient than a reference card or many other apps that I have seen. Overall, it is very simple, effective, efficient, and easy to use for photographers of any skill level. Although, I wish that it included aperture. Also, is the base shutter speed with or without the ND filter? ### 4/5 — Funktioniert einwandfrei *2020-04-15, version 2.0* Würde ich mir noch wünschen, dass nach dem Ablauf der Zeit ein akustisches Signal ertönt. ### 5/5 — Not behd *2020-02-16, version 2.0* Works great no issues at all simple app but saves plenty of time and hassle. I recommend it ### 4/5 — Ok I got how it worked now :) *2019-04-12, version 2.0* Simple app that does get the job done. It would be nice to have an alarm on the timer though. ### 5/5 — Simple, Easy,Straightforward, No Bullsh$t App. *2019-03-02, version 2.0* This free app was made by a landscape photographer friend of mine who is very serious of his craft. Very simple to use and most importantly it’s FREE 🙂 ### 5/5 — Great app *2018-09-08, version 2.0* I have been using the app for more then a year now . Very simple and easy . That’s what we need ### 5/5 — Great free ND exposure calculator *2018-06-10, version 2.0* This calculator is a great little app. Easy to use. Clean looking. Does the job perfectly. Thanks to the author for putting this out there!! ### 5/5 — Einfach. Top. *2018-02-06, version 2.0* Macht genau, was ich suchte. Belichtungszeiten für ND-Filter Kombis. ### 5/5 — Perfekt *2018-01-23, version 2.0* Super einfach zu bedienen und man kann ein helles oder dunkles Farbschema wählen. Timer am 30sek und aufteilest in full, half, third stops! ## Most critical reviews (10 lowest-rated) ### 1/5 — Gleich Werbung *2021-11-20, version 3.1.0* App installiert, gestartet und gleich erscheint eine Werbung mit Installtionsbutton in der Nähe des Homebutton vom Handy, wodurch ein versehentliches betätigen des Installationsbuttons der Werbung vorprogrammiert ist. Ich habe die App direkt wieder gelöscht… ### 1/5 — The app is great, but why the need to track me? *2021-06-02, version 3.1.0* I actually like the app but it asked me to track it. Why would a simple app like this need to track me at all? I’ve used it for years and would never suspect that it was tracking me across other apps and sites. No excuse for this. ### 1/5 — It freezes after each use. *2019-09-28, version 2.0* Looks good but freezes after each use and need to reinstall. ### 1/5 — Problem *2018-12-19, version 2.0* After update it now freezes after every process and needs to be rebooted Please fix great app !!!! ### 1/5 — App läuft nicht mehr *2018-08-21, version 2.0* Seit dem letzten iOS Update läuft die App leider nicht mehr. Der Entwickler hat sie zuletzt vor vier Jahren aktualisiert. Wir müssen uns also etwas neues suchen. ### 1/5 — Worked Once *2015-04-04, version 2.0* This app looked nice but it only worked once and then crashed. After that I was not able to open it again. I have an iPhone6 running iOS 8.2. I’ve deleted this app and gone to NDTimer. ### 2/5 — App ist gut. Werbung mit Installations Buttom schlecht *2021-09-30, version 3.1.0* Es ist mir klar, dass man für eine kostenlose App Werbung in Kauf nehmen muss. Ein No Go ist aber, dass diese Werbungen einen Installations Button für Software haben und dieser Button so platziert ist, dass man diesen ungewollt drücken kann. ### 2/5 — Necesitan Revisarla *2018-11-19, version 2.0* Es una aplicación fantástica, la que uso. Pero desde un tiempo para acá se congela, consigo el nuevo tiempo pero cuando quiero usar el cronómetro o volver a calcular otro tiempo tengo que cerrarla y volverla a abrir, espero que vuelva a funcionar como antes, merece las 5 estrellas si la corrigen ### 2/5 — Not what I expected *2016-12-02, version 2.0* Nice app but it doesn't factor in aperture. ### 3/5 — Great but needs improvements *2019-10-06, version 2.0* Really like this app. But it would be even better if there was an alarm - with sound - instead of vibrating. ## Most praised reviews (10 highest-rated) ### 5/5 — Great App, but it can be much better *2024-08-17, version 3.2.0* Great app, for which I was happy to make a donation. But if I can express a few wishes/suggestions for improvement: It would be great if you could put together a "filter bag". So the filter selection only includes filters that you have in your bag. That makes setting up easier. And another wish: To be able to edit my existing filters. For example, my ND 3.0 filter does not have the exact value. It would be good if you could set the filters precisely. Finally, combine 2 filters, then it will be an unbeatably good app. ### 5/5 — Very good app *2023-01-16, version 3.1.0* It works perfectly and has a very simple and intuitive interface. I would like to ask the developers to add an option to display the calculated time in seconds only. The new A7R5 has a built-in timer that accepts seconds only. It would must quicker to have the total time displayed in seconds so I do not have to convert minutes to seconds and then add the remaining seconds. ### 5/5 — Simple yet smart *2022-09-15, version 3.1.0* Does what it says in a straightforward manner. Recommended. ### 5/5 — Wunderbar und ohne Fehler *2022-06-12, version 3.1.0* Ich habe die App nun seit über einem Jahr im Einsatz und alle Berechnungen stimmten bisher. Die Aufnahmezeiten betragen dabei bis zu 45 Minuten. Die App ist einfach (positiv) aufgebaut und stellt alle wichtigen Funktionen zu Verfügung. Somit eine kostenfreie App die alle Parameter für die Langzeitfotografie schnell bereit stellt. Wen die unten eingeblendete Werbung stört, der darf gerne mit einem überschaubaren Betrag den Programmierer finanzieren. Was ich nicht verstehe ist, dass man sich darüber beschwert, dass die Werbung so angebracht ist, dass man darauf tippen kann. Das ist Sinn und Zweck ;-). Und ehrlich, wer Langzeitfotografie als sein Hobby sieht und dann das Geld nicht mehr für diese App übrig hat, sollte über seine finanzielle Gesamtsituation nachdenken. ### 5/5 — Perfect! *2022-05-14, version 3.1.0* Everything I need, nothing I don’t. Demystifies a lot of the ND process and makes it very easy. Happy to pay the $3.99 to get it ad free. Thank you! ### 5/5 — My go to calculator *2022-02-06* I have for many years now used Nisi filters as well as Lee and a few others. Lee and Nisi have their own apps but this is my go to app for calculating out the times. Simple and easy to use, just what you need when the light is changing fast. The functionality of this app is better than any others I have tried. Keep up the good work 😊 ### 5/5 — Simple and Convenient *2022-01-30, version 3.1.0* Nothing extra, quick and easy to use. ### 5/5 — Tutorial *2021-10-09, version 3.1.0* Can’t figure it out, is there a tutorial? ### 5/5 — Excellent *2021-06-16, version 3.1.0* A very user friendly app even for a novice like me, and includes a full range of Nd filters stops that other apps don’t include. Being a novice, I’m a bit confused about one of the settings called the “filter notation setting” it gives three settings but I don’t know which I should be using 1 optical density (Nd 0.3) 2 Filter factor (Nd 1024) 3 (none) Any help greatly appreciated ### 5/5 — Excellent *2020-11-05, version 3.0.0* Works perfectly. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
