see the FAQ

You may loose all your Moneroj if you use this App.

Based off monero v0.10.3.1 with pull requests #2238, #2239 and #2289 applied => so can be used in mainnet!
currently only android32
~~currently only use is checking incoming/outgoing transactions~~
works in testnet & mainnet
takes forever to sync due to 32-bit architecture
use your own daemon - it's easy
screen stays on until first sync is complete
saves wallet only on first sync and when sending transactions or editing notes
Monerujo means "Monero Wallet" according to https://www.reddit.com/r/Monero/comments/3exy7t/esperanto_corner/

Display outgoing pending transactions
wallet backup functions
adjust layout so we can use bigger font sizes (maybe show only 5 decimal places instead of 12 in main view)
review visibility of methods/classes
more sensible error dialogs ~~(e.g. when no write permissions granted) instead of just crashing on purpose~~
check licenses of included libraries; License Dialog
~~make it pretty~~ (decided to go with "form follows function")
~~spend monero - not so difficult with wallet api~~

No need to build. Binaries are included:
