Life In 19x19

Hi! Four or so years ago, I bought an Android tablet, and downloaded every Go app available at that time. (Not many!) Now I've finally been forced to update my tablet due to the natural bloating of appware relative to my minuscule 8g of memory. In the meantime, lots of my Go apps were uninstalled to make room for updating other apps.

Now I have quadrupled my storage memory, and am wondering what Go apps might be best to install.

I still have Champion Go (Crazy Stone) to play against, Go Free for an easy opponent for newbies,and Tsumego Pro.I think I have a Josecki program, too.

I guess what I need most are:

An SGF viewer that shows all the commentary, variations, etc.

An app that lets me enter games and save them as SGF files.

I used to have an app called NoGo which let you guess the next move when reviewing SGF files, but as I remember it ran into technical difficulties and stopped being developed. If you know of another app with that feature, I'd be glad to hear about it.

And anything else you recommend as particularly useful or interesting!

Thank you!

Bumping this, as I haven't yet found an Android app that will display the game tree or allow you to quickly jump to a different move number. Screen shots from NoGo look promising, but it doesn't seem to work on newer Android versions. Currently using BW-Go, and tried GridMaster but didn't like it. Any other suggestions?

For pro games, the Go4Go app allows to jump through the game with a slider.

And dont forget you can upload your game to lifein19x19.com and use the eidogo viewer to view the gametree, variations and comments on your android device too.
