Watch faces

Watch Face Chooser

A tool to select a suitable watch face.

_images/FacesApp.png

The app is intended to be enabled by default and has, therefore, been carefully structured to minimize memory usage when the app is not active.

Digital clock

Shows a time (as HH:MM) together with a battery meter and the date.

_images/ClockApp.png

Analogue clock

Shows the time as a traditional watch face together with a battery meter.

Digital dual clock

Shows a time (as HH and MM vertically) together with a battery meter.

Fibonacci clock

The Fibonacci sequence is a sequence of numbers created by the Italian mathematician Fibonacci in the 13th century. This is a sequence starting with 1 and 1, where each subsequent number is the sum of the previous two. For the clock I used the first 5 terms: 1, 1, 2, 3 and 5.

_images/FiboApp.png

Screenshot of the fibonacci clock application

The screen of the clock is made up of five squares whose side lengths match the first five Fibonacci numbers: 1, 1, 2, 3 and 5. The hours are displayed using red and the minutes using green. When a square is used to display both the hours and minutes it turns blue. White squares are ignored.

To tell time on the Fibonacci clock you need to do some calculations. To read the hour, simply add up the corresponding values of the red and blue squares. To read the minutes, do the same with the green and blue squares. The minutes are displayed in 5 minute increments (0 to 12) so you have to multiply your result by 5 to get the actual number.

Word clock

Shows a time as words together with a battery meter and the date.

Built-in

Heart rate monitor

A graphing heart rate monitor using a PPG sensor.

_images/HeartApp.png

This program also implements some (entirely optional) debug features to store the raw heart data to the filesystem so that the samples can be used to further refine the heart rate detection algorithm.

To enable the logging feature select the heart rate application using the watch UI and then run the following command via wasptool:

./tools/wasptool --eval 'wasp.system.app.debug = True'

Once debug has been enabled then the watch will automatically log heart rate data whenever the heart rate application is running (and only when it is running). Setting the debug flag to False will disable the logging when the heart rate monitor next exits.

Finally to download the logs for analysis try:

./tools/wasptool --pull hrs.data

Stopwatch

Simple stop/start watch with support for split times.

_images/StopclockApp.png

Step counter

Provide a daily step count.

_images/StepsApp.png

The step counts automatically reset at midnight.

Settings application

Allows a very small set of user preferences (including the date and time) to be set on the device itself.

_images/SettingsApp.png

Note

The settings tool is not expected to comprehensively present every user configurable preference. Some are better presented via a companion app and some particular exotic ones are perhaps best managed with a user-provided main.py.

Software

A tool to enable/disable applications.

_images/SoftwareApp.png

Most applications are disabled by default at boot in order to conserve RAM (which is in short supply and very useful to anyone wanting to write an application). This tools allows us to boot and conserve RAM whilst still allowing users to activate so many awesome applications!

Pager applications

The pager is used to present text based information to the user. It is primarily intended for notifications but is also used to provide debugging information when applications crash.

Applications

Alarm Application

An application to set a vibration alarm. All settings can be accessed from the Watch UI.

Calculator

This is a simple calculator app that uses the build-in eval() function to compute the solution.

Logo demo for PineTime

This demo is simply an alternating sweep of the Pine64 and MicroPython logos. It cycles through a variety of colours and swaps between the logos every 5 images (so if you change anything make sure len(colors) is not a multiple of 5).

_images/DemoApp.png

The demo also includes code to keep the devie awake making it suitable to run as an always-on application to demonstrate wasp-os at conferences and shows.

Note

Due to it’s niche purpose and relatively large size this app is not included by default in the flash images. It must be separately installed and enabled.

Flashlight

Shows a pure white screen with the backlight set to maximum.

_images/TorchApp.png

Haiku viewer

These three lines poems are fun to write and fit nicely on a tiny screen.

_images/HaikuApp.png

If there is a file called haiku.txt in the flash filesystem then this app allows it to be displayed three lines at a time using the pager.

This application also (optionally) loads an icon from the filesystem allowing to be customized to match whether theme your verses are based around.

Morse translator and notepad

This app is a simple morse translator that also doubles as a notepad. Swipe up for a line, swipe down for a dot, tap for end letter, double tap for end word. Up to 7 lines of translation will be displayed on a 240x240 screen, and old lines will be deleted. There is a preview of the next letter at the bottom of the screen.

Music Player for GadgetBridge

Music Player Controller:

  • Touch: play/pause
  • Swipe UPDOWN: Volume down/up
  • Swipe LEFTRIGHT: next/previous

Sports timer

A combined stopwatch and step counter.

Self Tests

A collection of tests used to develop features or provide useful metrics such as performance indicators or memory usage.

_images/SelfTestApp.png

Timer Application

An application to set a vibration in a specified amount of time. Like a kitchen timer.

Games

Conway’s Game of Life

The Game of Life is a “no player game” played on a two dimensional grid where the rules interact to make interesting patterns.

_images/LifeApp.png

Screenshot of the Game of Life application

The game is based on four simple rules:

  1. Death by isolation: a cell dies if has fewer than two live neighbours.
  2. Death by overcrowding: a cell dies if it has more than three live neighbours.
  3. Survival: a living cell continues to survive if it has two or three neighbours.
  4. Reproduction: a dead cell comes alive if it has exactly three neighbours.

On 11 April 2020 John H. Conway who, among many, many other achievements, devised the rule set for his Game of Life, died of complications from a COVID-19 infection.

The Game of Life is the first “toy” program I ever recall seeing on a computer (running in a mid 1980s Apple Macintosh). It sparked something even if “toy” is perhaps an underwhelming description of the Game of Life. Either way it occupies a special place in my childhood. For that, this application is dedicated to Professor Conway.

Play 2048

A popular sliding block puzzle game in which tiles are combined to make the number 2048.

Snake Game

This is a classic arcade game called snake.

_images/SnakeApp.png

Screenshot of the snake game

You have to direct the white snake to the food block (blue dot) by swiping in the desired direction. You must not hit the border or the snake’s body itself. Every time the snake eats the food, its length increases by 1. (In the current version there is an error that the length of the snake is not increased by 1 when the snake gets the food for the first time. This has to be fixed).

Once the game is over, you can try again by tapping on the screen and then swipe in the direction you want to move. If you want to leave the game, simply wipe in any direction once the game is over.

And now: Have fun playing! :)
