I had an Amazfit BIP for a while that had a color e-paper display with a battery that lasted over 30 days. I think they have since gone OLED but one cool thing about it was, while they had their own app with a login, I could alternatively sync it directly with a third party app on Android that was called “Notify And Fitness”. I only mention it because within this particular app the info never left the device. Perhaps there is something similar today, but I have since just given in and gone Garmin.
Gotta wonder if that would work. My impression is that they are kind of looping inside the model to improve quality but that the looping is internal to the model. Can’t wait for someone to make something similar for Ollama.
