The app will not open a database file stored on external sd card (and instead of saying so  it gives the scary error message that the file is not a database). Once I copied the database to internal memory  it opened without any problem. User interface could use lots of improvement. Have to use PgUp and PgDn buttons instead of scrolling through all records in a table (looks like this is implemented this way for quickness when browsing through large tables). No pinch-to-zoom in or out. Ability to execute native sqlite dot commands (like .dump and .schema) would be a big improvement. But the app has a lot to recommend it - it's probably your best bet for editing sqlite databases on your android device.
