Note however that unlike Organic Maps, CoMaps lacks support for old devices. Without Organic Maps, an old iPad would be a useless junk instead of a great navigation aid.
On Android, CoMaps works on Android 5, which is not bad at all. But they are probably going to drop support for Android 5 soon because libraries might themselves drop support for Android 5 (Organic Maps will probably have the same issue).
