Longtime favorite camera app crashes all the time – ClassicToy Review

I've loved this camera app for a long time but the last two (or so) versions can't keep from crashing on recent and current iOS (10.0.2, iPhone 5). Update: using ClassicToy on my iPhone 7. Same crashing. Now my favorite iPhone camera only in my memory. If it would be updated to something stable I'd start using it again in a heartbeat.
