The Barclay Howlers

Does anyone else have problems with the geocaching app cars go their iPhone. I have an up to date iPhone 6s that crashes after a while when using the official geocaching app. It then takes ages to restart. Can anyone offer any help?

Hi. Seeing that the classic geocaching app is being sicobtinued it appears that I won't be able to cackle until I find an app that shows the caches on footpaths as my caving is always done out in the countryside. Can anyone recommend a good simple app for iPhone ?
