Hello, i haven't tried out the app yet, but i just have one suggestion to make.
If it is possible, could you somehow make an offline version? possibly with a downloadable database or something? It's just because most of the time that i need wolfram alpha (at school), i have very very bad coverage, so I am unable to use the internet.
If you could, that would be awesome, but if you can't, don't worry about it.
