## Example Applications
To make the process easier we've come up with some example applications that you can use as a base
when creating your own. Just come up with a unique 7 character name, copy `apps/_example_app`
or `apps/_example_widget` to `apps/7chname`, and add `apps/_example_X/add_to_apps.json` to
when creating your own. Just come up with a unique name (ideally lowercase, under 20 chars), copy `apps/_example_app`
or `apps/_example_widget` to `apps/myappid`, and add `apps/_example_X/add_to_apps.json` to
`apps.json`.
**Note:** the max filename length is 28 chars, so we suggest an app ID of under
20 so that when `.app.js`/etc gets added to the end the filename isn't cropped.
**If you're making a widget** please start the name with `wid` to make
it easy to find!

## Modules
You can include any of [Espruino's modules](https://www.espruino.com/Modules) as
normal with `require("modulename")`. If you want to develop your own module for your
app(s) then you can do that too. Just add the module into the `modules` folder
then you can use it from your app as normal.
You won't be able to develop apps using your own modules with the IDE,
so instead we'd recommend you write your module to a Storage File called
`modulename` on Bangle.js. You can then develop your app as normal on Bangle.js
from the IDE.

Monitor Heart Rate Variability using the Bangle.JS
===================================================
One-time mode:
-------------
This will take a HRV measurement over a single approx 30 second period. It will also provide you with a HR reading based on the post-processing of the signal.
HRV metrics displayed are currently RMSSD (Root Mean Square of the Successive Differences) and also SDNN (standard deviation of NN intervals).
Continuous mode:
----------------
This will continually take measurements over 30 second periods every 3 and half minutes and log them to a CSV file on the Bangle until the watch is reset; this file can then be reviewed in Excel or other apps. The log file is reset each time you restart and select this mode to save on storage. The log file is just 1 line per each 3 minute cycle showing: timestamp, HR, SDNN, RMSSD, sample count, Temp (uncalibrated CPU temp), and movement based on the accelerometer. The additional metrics aside from the HRM data are useful in analysing sleep.
Note that in both modes, if the watch seems unresponsive, it's processing data and if you continue to hold the reset button it will eventually restart.
If your sample count is less than around 5 samples and/or the readings don’t look right, try repositioning the watch and try again - you can use the HR monitor app to confirm fitting.

# UI/UX for Espruino Smartwatches
This is a very basic app that defines a common UI/UX for espruino smartwatchesm and specifically for the *bangle.js*, also it displays dinamically calculated x,y position coordinates and screen areas based in detected smartwatch models.
Launcher icon
![](UI4swatch_icon.png)
1st screen - Main page
![](UI4swatch_s1.png)
## Usage
Open and see x,y coordinates for areas
Interact with buttons or touch screen to print the event or leave the app
## Features
Colours, font, user input,, load widgets
## Controls
Press left area - Prints Touch1
Press righ area - Prints Touch2
Press center area - Prints Touch3
Swipe Left - Prints <--
Swipe Right - Prints -->
BTN1 - Prints Button1
BTN2 - Prints Button2
BTN3 - Quit to Launcher
## Support
This app is so basic that probably the easiest is to just edit the code
Otherwise you can contact me [here](https://github.com/dapgo)

# Acceleration Logger
Logs XYZ acceleration data (at the normal 12.5Hz) to a CSV file that can be downloaded to your PC.
## Usage
* Run the app 'Accel Log' from Bangle.js menu
* Optionally choose a file number if you want to record to multiple different files.
* Choose `Start`
* Acceleration data will now be recording
* When you're done, press `BTN2`
## Downloading Data
* Go to the Bangle.js App Loader
* Connect to your Bangle
* Under `My Apps` look for `Acceleration Logger`
* You'll see a download arrow next to it - click that
* You can now choose to Save or Delete each track you have recorded

Alpine Navigator
================
App that performs GPS monitoring to track and display position relative to a given origin in realtime.
![screenshot](./sample.png)
Functions
---------
Note if you've not used GPS yet I suggest using one of the GPS apps to get your first fix and confirm as I've found that helps initially.
The GPS and magnetometer will be turned on and after a few moments, when the watch buzzes and the dot turns from red to pink, that means the GPS is fixed. all your movements now will be displayed with a line drawn back to show your position relative to the start. New waypoints will be added based on checking every 10 seconds for at least 5 meters of movement. The map will scale to your distance travelled so the route will always remain within the window, the accelerometer/pedometer is not used - this is a purely GPS and compass solution so can be used for driving/cycling etc. A log file will be recorded that tracks upto 1000 waypoints, this isn't a big file and you could remove the limit but I've kept it fairly conservative here as it's not intended as a main feature, there's already good GPS recorders for the Bangle. The following other items are displayed:
1. altitude at origin, this is displayed left of the centre.
2. current altitude, displayed centre right
3. distance from origin, bottom left (meters)
4. distance travelled, bottom right (meters)
5. compass heading, at the top
For the display, the route is kept at a set resolution, so there's no risk of running into memory problems if you run this for long periods or any length of time because the waypoints will be reduced when it reaches a set threshold so you may see the path smooth out slightly at intervals.
If you get strange values or dashes for the compass, it just needs calibration so you need to move the watch around briefly for this each time, ideally 360 degrees around itself, which involves taking the watch off. If you don't want to do that you can also just wave your hand around for a few seconds like you're at a rave or Dr Strange making a Sling Ring but often just moving your wrist a bit is enough.
The buttons do the following:
BTN1: this will display an 'X' in the bottom of the screen and lock all the buttons, this is to prevent you accidentally pressing either of the below. Remember to press this again to unlock it! soft and hard reset will both still work.
BTN2: this removes all waypoints aside from the origin and your current location; sometimes during smaller journeys and walks, the GPS can give sporadic differences in locations because of the error margins of GPS and this can add noise to your route.
BTN3: this will pause the GPS and magnetometer, useful for saving power for situations where you don't necessarily need to track parts of your route e.g. you're going indoors/shelter for some time. You'll know it's paused because the compass won't update it's reading and all the metrics will be blacked out on the screen.
Things to do next
-----------------
There's a GPS widget that's been developed to leverage low-power mode capability on the sensor, will look to incorporate that.

# Arrow Compass
A variation of jeffmer's Navigation Compass. The compass points
North and shows the current heading.
This is a tilt and roll compensated compass with a linear
display. The compass will display the same direction that it shows
when flat as when it is tilted (rotation around the W-S axis) or
rolled (rotation around the N-S) axis. *Even with compensation, it
would be beyond foolish to rely solely on this app for any serious
navigational purpose.*
![](arrow_screenshot.jpg)
## Calibration
Correct operation of this app depends critically on calibration. When
first run on a Bangle, the app will request calibration. This lasts
for 30 seconds during which you should move the watch slowly through
figures of 8. It is important that during calibration the watch is
fully rotated around each of it axes. If the app does give the
correct direction heading or is not stable with respect to tilt and
roll - redo the calibration by pressing *BTN3*. Calibration data is
recorded in a storage file named `magnav.json`.
It is also worth noting that the presence of the magnetic charging
clamps will require the compass to be recalibrated after every
charge.
## Controls
*BTN1* - switches to your selected clock app.
*BTN2* - switches to the app launcher.
*BTN3* - invokes calibration ( can be cancelled if pressed accidentally)
## Issues
* detect when calibration data is missing
## Acknowledgement
This app is based in the work done by [jeffmer](https://github.com/jeffmer/JeffsBangleAppsDev)

Astral Clock
============
Clock that calculates and displays Alt Az positions of all planets, Sun as well as several other astronomy targets (customizable) and current Moon phase. Coordinates are calculated by GPS & time and onscreen compass assists orienting.
![screenshot](./Example.PNG)
<sup>(The clock does have Pluto now - felt bad for leaving it out)</sup>
Functions
---------
**BTN1**: Refreshes Alt/Az readings. The coordinates are NOT continually updated, this is to save resources and battery usage plus it avoids you having to wait for calculations to finish before you can do anything else on the watch - it doesn't take long but it could still be annoying.
**BTN2**: Load side-menu as standard for clocks.
**BTN3**: Changes between planet mode and extra/other targets - discussed below (will still need to press button 1 after switching to update calcs).
**BTN4**: This is the left touchscreen, and when the LCD is on you can use this to change the font between red/white. This will only work after the GPS location has been set initially.
The text will turn blue during calculation and then back again once complete.
When you first install it, all positions will be estimated from UK as the default location and all the text will be white; from the moment you get your first GPS lock with the clock, it will save your location, recalculate accordingly and change the text to red, ideal for maintaining night vision, the calculations will also now be relevant to your location and time. If you have not used the GPS yet, I suggest using it outside briefly to get your first fix as the initial one can take a bit longer, although it should still just be a minute or 2 max normally.
Lat and Lon are saved in a file called **astral.config**. You can review this file if you want to confirm current coordinates or even hard set different values \- although be careful doing the latter as there is no error handling to manage bad values here so you would have to delete the file and have the app generate a new one if that happens, also the GPS functionality will overwrite anything you put in here once it picks up your location.
There can currently be a slight error mainly to the Az at times due to a firmware issue for acos (arccosine) that affect spherical calculations but I have used an estimator function that gives a good enough accuracy for general observation so shouldn't noticeably be too far off. I\'ll be implementing acos for better accuracy when the fix is in a standard release and the update will still include the current estimate function to support a level of backward compatibility.
The moon phases are split into the 8 phases with an image for each - new moon would show no image.
The compass is displayed above the minute digits, if you get strange values or dashes the compass needs calibration but you just need to move the watch around a bit for this each time - ideally 360 degrees around itself, which involves taking the watch off. If you don't want to do that you can also just wave your hand around for a few seconds like you're at a rave or doing Wing Chun Kuen.
Also the compass isn\’t tilt compensated so try and keep the face parallel when taking a reading.
Additional Astronomy Targets
----------------------------
There are currently 12 extra targets as default in the config file, and these were selected based on well known named objects listed in various sources as good choices for both binoculars and telescopes. The objects are processed and then 9 are displayed and ordered descendingly by altitude on the basis those higher up will have better visibility.
You can input different objects rather than those listed in the galaxies/extras mode by changing the astral.config file with the relevant details for: Object name, Right Ascension and Declination, below is an example. Again, there is little in the way of error handling to streamline the app so be sure to input these in exactly the same format as you see in the file, namely signed 6 digit values with double quotes, example:
*{"name": "Andromeda", "ra": "004244", "de": "411609", "type": 3}*
The type property is not utilised as yet but relates to whether the object is (in order): a cluster, nebula or galaxy. If you try putting more than 12 or so, the clock will try processing all of them but I advise against doing that because you will get memory errors if you put in too many. A better approach is to put a limited set in seasonally based on what's best in your location.
Updates & Feedback
------------------
Put together, initially at least, by \"Ben Jabituya\", https://jabituyaben.wixsite.com/majorinput, jabituyaben@gmail.com. Feel free to get in touch for any feature request. Also I\'m not precious at all - if you know of efficiencies or improvements you could make, just put the changes in. One thing that would probably be ideal is to change some of the functions to inline C to make it faster.
Credit to various sources from which I have literally taken source code and shoehorned to fit on the Bangle:

# Authentiwatch - 2FA Authenticator
## Supports
* Google Authenticator compatible 2-factor authentication
* Hash calculations:
* Bangle 1: SHA1 only (same as Google Authenticator)
* Bangle 2: All (SHA1, SHA256, SHA512)
* Timed (TOTP) and Counter (HOTP) modes
* Custom periods
* Between 6 and 10 digits
* Phone/PC configuration web page:
* Add/edit/delete/arrange tokens
* Scan QR codes
* Produce scannable QR codes
## Usage
* Use the Phone/PC web page interface to manage the tokens stored on the watch.
* Tokens are stored *ONLY* on the watch.
* Swipe right to exit to the app launcher.
* Swipe left on selected counter token to advance the counter to the next value.

# BangleRun
An app for running sessions. Displays info and logs your run for later viewing.
## Compilation
The app is written in Typescript, and needs to be transpiled in order to be
run on the BangleJS. The easiest way to perform this step is by using the
ubiquitous [NPM package manager](https://www.npmjs.com/get-npm).
After having installed NPM for your platform, checkout the `BangleApps` repo,
open a terminal, and navigate into the `apps/banglerun` folder. Then issue:
```
npm i
```
to install the project's build tools, and:
```
npm run build
```
To build the app. The last command will generate the `app.js` file, containing
the transpiled code for the BangleJS.
