The user interface itself is amazing, true seamless multiple device support - including web clients (with your drafts synced on all your devices too), live location sharing, polls, live voice channels, good stickers, bots, public groups/channels, 2gb file sharing, video messages, usernames, etc.
Signal is only good at doing one thing, and that’s encryption. It lacks so many useful features that Telegram has.
Organic Maps is indeed open source and available through f-droid/GitHub/Telegram.
It’s actively developed and it’s UI is more easier to use than OSMAnd. The search accuracy is also way better than in OSMAnd, in which I often can’t find places.
OSMAnd is pretty nice, but Organic Maps is just way better IMHO.
Have you tried OnlyOffice? It’s pretty much like MS office and documents compatibility is really good.
Because the only good thing about Signal is it’s encryption.
