I've had a tidy up on both my android phone and tablet - I had an iPad before my android tablet and didn't realise that google playstore keeps my apps for me so even if I delete off my phone or tablet, I still have the apps that I can put back on. Also Amazon does the same. I didn't realise that until I started to read in this thread and wondered how I was going to get on with deleting apps I had paid for.
So if push comes to shove, I'll just delete all my other apps to make room for the Fool's Dog tarot apps (especially the Liber T)
