It's a great start!
Boost for Lemmy
Community of the Android app Boost for Lemmy

Not sure if it's Boost or YouTube Revanced at fault but got the following error when I tried to open a Lemmy link to a video: https://postimg.cc/q6sW77x0
Also, the sign-up journey is a bit confused. Clicking sign up takes me to joinlemmy, which then just lands me on a home page for whichever instance I click. Might be more user friendly to prompt for a choice of instance and take them directly to that instance's sign up page. And maybe have a button for "not sure? Explore here" or something similar that would take you to joinlemmy
Being taken to the instance that just selected makes pretty firm logical sense to me, personally. Is the sign up process/path uniform across all instances?
The few I checked were, but not sure if the path is defined as part of the Lemmy protocol.
Is there an option for the comments where I can just long-press to select and copy text instead of needing to go into a copy menu and then using the select text option? That can be bit tedious, and I typically copy most longer comments and send them to my voice-aloud app for TTS. It's definitely the main feature I miss about the old RIF app - easy text selection and perfect Bluetooth keyboard/mouse support.
Images are able to be posted in comments. Ability to press and make them bigger would be useful.
Understood would be difficult with the press to collapse feature.
I grabbed the testing version because I'm very excited for Boost to return! Unfortunately I found an issue right away. It appears that the app doesn't support 2FA for instances that use it. I got an error stating "missing totp token."
Should old boost users who have paid for boost for reddit, get the premium by default??
+1 This shouldn't even be something people need to ask.
But I'm assuming that this is the first version so maybe the dev will make it happen in an upcoming update
