Repeatedly crashes on iPad and iPhone, barely useable – True HDR Review

Bought this and its companion app a couple of years ago. Initially impressed, but lately it's become unusable. It crashes on my iPad and iPhone when choosing pictures. Rarely do I succeed in merging two resolutions anymore. iPad7,4 MPGH2LL/A iOS 10.3.3 TrueHDR 3.3.1 iPhone9,2 MN5Y2LL/A iOS 11.4 TrueHDR 3.3.1
