Great App, but it can be much better

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.

Very good app

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.

Simple yet smart

Does what it says in a straightforward manner. Recommended.

Wunderbar und ohne Fehler

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.

Perfect!

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!
