Ratings and reviews

2nd Update 11/7/25 I could upload the first animation but when I go to add another it isn't going to my phones photo album it only let's me choose the one I just uploaded. I tried graffiti too and it doesn't work. UPDATED 11/7/25 I've installed the update and it worked. It let me send a picture from the program list. Thank you for fixing it.

Garbage. Can't import shared images and animations. Updating the app deletes those anyways. If you bought a sign that uses this app, return it. Update: Cool, now the app just makes all the custom graffiti I make just disappear out of thin air, no update needed. It's very frustrating to have images that I spend an hour or so recreating just for them to delete themselves. This is unacceptable.

App is decent for what it is. Sometimes apps used with third party products on Amazon can be iffy, sometimes don't work the greatest, and you can just tell they were put together quickly. But this app actually has a pretty good variety of graphics to change your LED sign. Works as it should, haven't had any issues with it. Updated with new graphics since using. I do wish it were easier to add own graphics. It can be done but it takes some work to get images to look nice.
