BangleApps VS Espruino

You can fo so by going on https://banglejs.com/apps, then in the More... tab you'll see a section called Device info > Apps Installed

You should take a look at Bangle https://github.com/espruino/BangleApps, it does pretty much this, it's running a js engine on the MCU and you can download apps and run them just like you describe.

But I am still wondering where this code in my screenshot comes from. I suppose it is telling the calling env how to clean up after it. But I couldnt find anything about that on the git repo. It is there tho when loaded through the app loader. https://github.com/espruino/BangleApps/tree/master/apps/lcars

AGPS data just enables the Watch to get a position in a few seconds. It can get the information (almanac) from the satellites but this takes several minutes of constant direct view to clear sky. Which of the agps apps did you try? https://banglejs.com/apps/?q=agps

So far I only have used the Browser based "Assisted GPS Updater (AGPS)" one and so far have no issues.

Depending on your messagegui App, in the default Message UI one just touch the icon on the left of the title bar and then choose Mark all as read, more details here. However, I can recommend the newer Message List App which has a much nicer interface, in my opinion, and provides a dedicated button for dismissing all messages.

Their "app store" is online [0] and you can actually review the source code for all of the apps on it by clicking the github icon on each entry, here's one for example [1]

Not for PineTime, but the bangle.js has a a 2FA TOTP app: https://banglejs.com/apps/?id=authentiwatch

BangleJS should fit your requirements pretty well. It's a Chinese made smartwatch sold with a custom open and hackable rom. It pairs to android via Gabdgetbridge which is FOSS too

Here's a JavaScript smart watch running that - Bangle.js.

Espruino

The Bangle.js 2 is an excellent device. As a former Pebble user, this is the first device that I consider an adequate replacement for my Pebble (which by now has a diminished battery life and corroded charging contacts).

Here is my impression of the Bangle.js 2:

- Battery: Lasts about 3 weeks on a charge, constantly connected to my phone, when the watch is used to display notifications and alarms. This is a major advantage over Apple Watches and Android/Wear OS watches.

- Display and buttons: The 1.3" 8-color transflective display is comparable to the Pebble Time series' 64-color transflective display. The display is always on, and the backlight activation is highly configurable. The Bangle.js 2 has a touchscreen and 1 button, while Pebble watches have no touchscreen and 3 buttons.

- Software: Runs on the completely free and open source Espruino JavaScript interpreter,[1] which was my main motivation for purchasing this device. There are currently 336 apps in the web-based Bangle.js app loader (app store), including utilites and clocks (watch faces), all of which are FOSS. The bootloader and firmware can be updated directly from the app loader. On Android, there is a distribution of Gadgetbridge (built from the same code base as Gadgetbridge) with internet access enabled that integrates the Bangle.js app loader into Gadgetbridge, which makes it very easy to use the watch.[2]

- Build: Built on the same device body as the SMA Q3.[3] The casing is plastic, and the watch is compatible with standard 20 mm watch straps. The IP67 water/dust resistance makes the watch usable for sports.

Overall, I highly recommend the Pebble.js 2 watch, which is the best FOSS-focused watch I have found to date.

This is the firmware repo for the BangleJS : https://github.com/espruino/Espruino

This makes use of a JS interpreter made for embedded devices: Espruino

More details in the Espruino repo: https://github.com/espruino/Espruino

There are subsets of JS for embedded device e.g. Espruino https://github.com/espruino/Espruino for BangleJS https://shop.espruino.com/banglejs also with 4MB or JerryScript https://jerryscript.net
