There's a new version (technically it's a different app called "My Opening Hours" and a link can be found on this page somewhere), which I'll continue to update. This old version is only for old devices and/or people who like features that are not yet available in the new one (OpenStreetMap support).
A simple application for maintaining a list of places and their opening hours. The opening hours can be shared via OpenStreetMap.
