App Doesn’t Work
Alignment sucks
Response from developer
Hi Roelof, Thank you for your feedback, and we're sorry you had this experience. We finally tracked down the cause of this alignment issue after several hours of testing. In rare cases, focus stack files were not being processed in alphabetical order, which could lead to incorrect alignment results. We've already fixed this issue, and the update will also include significantly improved alignment algorithms that make stacking more robust and accurate overall. We appreciate you taking the time to report the problem, and we hope you'll give the updated version a try once it's available. Best regards, The iFocus Stacking team
Exceeds Expectations!
Simple and works
Excellent stacking app
Surprisingly good!
Top marks!
Ideal for iPhone based focus stacking
Also very importantly, there was an issue when I first made my purchase, I contacted support and received a very prompt and helpful reply. The problem was already on their list and they solved it, quickly. I find this reassuring. So thank you very much for your help.
So if you want to process your focus stack then use this app.
