Whilst Google photos and flickr are slogging their way along, vying to be first to upload any image from my phone, I realised that there are already two clear winners in this race and its not the tortoise or the hare. First is Dropbox, which I have reinstated (I suspect it might have been nobbled by either google backup or flickr's uploadr but it did have a significant app update around the same time, so I haven't notified the stewards yet!). I didn't find carousel so useful but dropbox is really simple, solid and still has the very logical private sharing options. I could live without it but I love the reliability of knowing soon after I find a WiFi spot my phone images are up on a private cloud (flickr could safely substitute here). The second is a surprise, its QuickPic, an alternative to the native gallery app or Google Photos itself. Compared with Google Photos its a real lightweight with a tiny memory footprint but its fast and does exactly what I expect from a photo gallery app. More importantly it plays nicely with other phone apps.
Whilst the other race is still on, flickr is becoming my favourite as a stayer.
