I love Slowly, been obsessed with it for the past couple of weeks since I discovered it in the Play Store. A great experience overall but here are my issues:
(1) even though most users seem to be eager to have a deeper conversation, some of them just type "hey, do you wanna be friends?" which is pretty annoying. The app even warns the user if they try to send a very short letter but I think that maybe it should not be allowed at all.
(2) there's an option in auto-match to only message users that have been online in the past few days. That's great for the ones sending the letters but I get so many letters per day that I get overwhelmed and can't reply to all of them the way I should. For that reason I turned auto-match off but that's not ideal because I like it. I wish there was a way to set an auto-match acceptance limit, like "1 per day" and same for letters from people you haven't written with yet.
(3) very small selection of avatars. I keep confusing some of my penpals for each other because they have the same avatar and write similarly/come from the same country. I think it wouldn't be an issue if there were more avatars to choose from (I love the fact you cannot use a photo though)
(4) I wish I could preview exactly what my profile looks like to others. Small thing but still :)
I can't think of anything else at the moment.
Let me repeat that I LOVE THIS APP, I just think it could be even better ⭐
