Ratings and reviews

Good app but would be perfect if the live frame is bigger, if more film profiles such as Fuji or lomography film stock. Too bad it's only live in color and B&W but can't mimic the film effect & color live on screen before shooting too. The most disappointing thing is it can't save the picture from the logbook to the phone. Overall it is Good, just not as good as it should be.

it used to work very good. But since past few months, whenever I open the app, it just freezes at the start, it doesn't get past the logo. So I can't access the app, not can I contact the developer as the app doesn't open.

this is a 2 X awesome light meter. the last coupke years I've tried them all and this is absolutely the v best.. in fact the next couple of months I'll be giving my grandson a camon ae1 program and your program will be his first download. This will eliminate his stress and guess work
