@derbydeserter said in Adding an app to my App List on v1.5.2 M5Stack Fire: ...can download and run it on the M5Stack Fire Are you sure you used the Download button within uiFlow and not the Play/Run button? There is a 1-second timeout after boot up that allows the user to press the App, " : ", and Setup buttons. When you use the Download feature within uiFlow, it will download your app to your device, and then it should show up in the App list. Be sure to rename your Project name from "main" in the upper left of uiFlow so you can distinguish it from other apps. If not, it will overwrite main.py each time. For deleting apps within the Apps menu, in v1.4.5.x you would hold the ▼/DEL button to delete them. However, I think there is a bug in v1.5.x and there is not an option to delete. You will need to delete them manually from the /flash/apps directory by using ampy, Thonny, etc.
