The Signal Foundation does work on Signal Desktop - but they only release binaries for Mac, Windows, and Debian-based Linux distros. Those are the downloads available on their website, there is no link to the Flatpak on their website.

The community turns that official Debian release into an unofficial Flatpak release. This means that you need to trust the community packagers to be doing the right thing, along with trusting the Signal Foundation. It’s an additional layer of trust that you wouldn’t need for an official release.

An alternative option would be building the app yourself - there’s documentation here and the repo is here, but then you’re responsible for keeping up and rebuilding when they have updates. I definitely hope the Signal Foundation releases an official Flatpak, it’s not a great position to be in if you’re not on a Debian-based distro.

Just a note that the flatpak is not made by the Signal Foundation, it is maintained unofficially by the community. See the last sentence on the app description on Flathub:

This flatpak is maintained by the Flathub community, and is not necessarily endorsed or officially maintained by the upstream developers.

There’s a discussion about the community flatpak’s trustworthiness on their repo here and here, a feature request for the Signal Foundation to have an official distro-agnostic release here, but for now the only official Linux release of Signal is for Debian-based distributions.

Accrescent is in early alpha, but it looks like it’s on its way to be a great, modern app store.

I found the My Deep Guide youtube channel to be a really good source of reviews when I was choosing an eink tablet, here’s a link to his 2022 roundup.

I went with a Supernote A5X around 2.5 years ago. My usecase was for college to take lecture notes and to read academic papers/epubs. I went with the Supernote over the reMarkable for the software support: I really like the concept of reMarkable’s Linux-based OS and being able to use community mods, but it felt like I would need the mods to have all the features I wanted, while the Supernote wouldn’t allow for modification but would have everything I wanted built in. I’ve been satisfied with the writing and reading experience, customer support is responsive via email and Reddit, and OS updates have been adding new features without a subscription.

I’m very excited about this - Apple has such a polished customer care experience where you can walk into any Apple Store that Google hasn’t matched. Increasing the options for in-store repair from just Asurion/uBreakiFix to more stores is big for my peace of mind.

Starting with Android 12 (and maybe earlier, I think it may be a part of a Google Play update?), you can delete your advertising ID in settings - definitely worth doing!

I’m a software nerd, my biggest priority is keeping Android up-to-date on security and features, so it really seems like Samsung would be the best fallback option with a proven track record of getting security updates out as quick (or quicker) than Google and typically promising 4 years of OS upgrades/5 years of security patches (here’s an article with many phone manufacturers policies). I’d really miss the stock Android experience and unlockable bootloader though!
