I have a love-hate-love relationship with this app. It has no serious competitors for reading Wikipedia offline on Android  and the interface is slick and pretty when it's working (and the OSX version is spectacular). But I dread every update  or moving to a new phone  because there's a large chance the app breaks. In the new version  the app was unable to find a long-used ZIM file on my SD card (yes  I switched to external storage in settings) and was just """"""""searching..."""""""" endlessly. I had to re-download the entire WIkipedia again *twice* before it was able to find the new ZIM file correctly and load it without crashing. I am grateful for this free app  and I know it's maintained and developed by perhaps only one person. But I would prefer more emphasis on robustness (and would be happy to support that financially!).""
