Hey this is great - just had a look for my mum! Couple of questions (which without watching are hard to answer) - why the modules on the F-Droid App Store and Firefox? As a (young(er!)) Android user I've used neither and would be unlikely to. I can't imagine my mum would use anything other than Play and Chrome, so it feels a little 'too far' for me, confusion for the sake of it?

Also a suggestion - pretty much everyone uses WhatsApp in the UK, mostly everyone I know will be in a WhatsApp group with their parents (and/or grandparents!). Definitely worth adding that as a module!
