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

I'd give this a PERFECT rating

Ease of use.
Technically viable.
Does what it says on the description.
Versatile: alternative ND filter notation:
Filter Factor (ND1024)
Filter Density (ND 3.0)

User is also able to specify the Shutter Speed EV Step to match camera setting (1/3 step, 1/2 step, or 1 Step).

Also has Dark colour scheme (white over black background) and Light colour scheme (black over white background).

Well done.
