I've written a quick script to build the firmware with just one specific WatchFace/App and print the resulting Memory/RAM usage of the firmware

I've done some slight modification to the firmware: I've created an empty Watchface, cleverly called WatchFace::Empty. When building with just one specific App the empty WatchFace is used

The script just builds all watchfaces/apps separately

The minimum with empty WatchFace and no Apps is 98.00 % with 64224 B

Very interesting. I wonder why the Digital face increases the static memory usage, while the Terminal face doesn't for example. Something to do with weather? Maybe font related? As for the others I'm taking a look into whether any of them can be optimised, would be nice to get a couple hundred bytes back if we could

Out of interest I bisected Metronome. All of the extra memory is due to the use of a dropdown, as LVGL has static variables that are dropdown specific and are stripped out when not used. So I'd guess most of the memory usage here is similar, just LVGL statics picking up a small amount of RAM usage. I might test a few more though

mark9064 Oct 3, 2024

FWIW Digital looks like it's all fonts. Opening the can of worms that is LVGL font handling is for another day methinks
