I don’t even mind the heavy ad presence because it’s free. However...
All this does is remind you to send the message. If you’re not at your phone to do it, it won’t send the message automatically.
Very misleading.
It pops up a reminder to send the Message, then when you click on it, it populates the message into the window for you so you can hit send.
It’s a good app IF that’s what you want, but I can do the same with my “reminder” app for free (no ads) and a few extra taps... not worth it.
