Devs make things they feel like making, or things they think the world needs.

What kind of an app (web, desktop, or mobile) would you want to see? What is something you wanted or needed for a long time that simply isn't there, or there but so bad with X that you can't use it?

Alternatively, what is a common problem that could be solved with software but hasn't been yet, or at least not effectively?

Leaving this vague on purpose, to let Tilderinos express themselves.

I know those are easy to find on children's education materials, but the keyword here is simple. Anything kiddie, requiring too many clicks or that takes 3 seconds is off the table.

I kinda need to brush up on my super basic reasoning. In part, because a grown man should know the time table by heart, and in part, because I wanna convince myself that I did not get brain damage after being hit by a car (there's really nothing indicating that, I'm just paranoid).

I'm looking for something simple that presents me with the multiplication table and or simple calculations to answer under a time frame. The requirement for iOS is that my computer is broken.

And it really can be super simple, even something I open from a mobile web browser or transfer to my Kindle.

Additionally: there is no need for if to be an app. A huge list of exercises (with answers) would be greatly helpful.

Thanks!

I've been using Textra for years, but there's some new protocol whose name I don't remember that Textra isn't compatible with. This results in some messages (primarily from other LG phones to my LG phone) going only to the LG Messaging app and not Textra, which is annoying. Any recommendations?
