The database app in LibreOffice, based on the Firebird database engine, can do all that.

I use Brevo as well. Free tier: 300 emails per day.

Very happy with them.

A couple of years ago, Canada required all carriers to cell unlocked phones, or allow them to be unlocked for free. Nothing bad has happened because of that. Our cell phone plans are still too expensive, and the companies are wildly profitable.

I think that one of the issues is weight. Batteries add an awful lot of weight to a mouse. If you use a wired mouse, it’s unbelievable how light it is. That could definitely improve your wrist problems.

I am a big fan of MyNoise, which mixes real-life recorded sounds, but you have a ridiculous amount of control over almost everything.

It’s browser-based, so compatible with any device. Once it has downloaded the sounds, it doesn’t use any more bandwidth.

Definitely worth supporting with a donation.
