It no longer works!

Ive used wiki off-line for the last couple of years. It worked well without any problems. Then in the last six months Ive found that installing it either on an iPhone or an iPad Air 2 it no longer works. It freezes frequently. Uninstalling it and its database and then reinstalling it has made no difference. It has become a big waste of money.

By the way, theres no one at the publishers who can be contacted about this. They dont seem to care.
