+# BuffGym
+
+This gym training assistant trains you on the famous [Stronglifts 5x5 workout](https://stronglifts.com/5x5) program.
+
+## Usage
+
+When you start the app it will wait on a splash screen until you are ready to start the work out. Press any of the buttons to start
+
+![](buffgym-scrn1.png)
+
+You are then presented with the programs menu, use BTN1 to move up the list, and BTN3 to move down the list. Once you have made your selection, press BTN2 to select the program.
+
+![](buffgym-scrn2.png)
+
+You will now begin moving through the exercises in the program. You will see the exercise information on the display. 
+1. At the top is the exercise name, e.g 'Squats'
+2. Next is the weight you must train
+3. In the center is where you record the number of *reps* you completed (more on that shortly)
+4. Below the *reps* value, is the target reps you must try to reach.
+5. Below the target reps is the current set you are training, out of the total sets for the exercise.
+6. The *reps* value is used to store what you achieved for the current set, you enter this after you have trained on your current set. To alter this value, use BTN1 to increase the value (it will stop at the maximum required reps) and BTN3 to decreas the value to a minimum of 0 (this is the default value). Pressing BTN2 will confirm your reps
+
+![](buffgym-scrn3.png)
+
+You will then be presented with a rest timer screen, it counts down and automatically moves to the next exercise when it reaches 0. You can cancel the timer early if you wish by pressing BTN2. If it is the last set of an exercise, you don't need to rest, so it lets you know you have completed all the sets in the exercise and can start the next exercise.
+
+![](buffgym-scrn4.png)
+![](buffgym-scrn5.png)
+
+Once all exercises are done, you are presented with a pat-on-the-back screen to tell you how awesome you are.
+
+![](buffgym-scrn6.png)
+
+## Features
+
+* If you successfully complete all reps and sets for an exercise, it will automatically update your weights for next time
+* Has a neat rest timer to make sure you are training optimally
+* Doesn't require a mobile phone, most 'smart watches' are just a visual presentation of the mobile phone app, this runs purley on the watch. So why not leave your phone and its distractions out of the gym!
+* Clear and simple user interface

 This gym training assistant trains you on the famous [Stronglifts 5x5 workout](https://stronglifts.com/5x5) program.
 
+## Configuration
+
+### Setting your start weight values
+
+You will want to set your own starting weight values for your 5x5 training program. To do this is easy! After installing this app, go to the BangleJS app store, connect to your watch, and navigate to the `My Apps` tab. In there you will find this app in the list, and an icon (a down arrow) to the right of the app title. Click that icon to reveal a configuration page. Enter your weights and other details, and click upload. That is it, you are now ready to train!

 You will then be presented with a rest timer screen, it counts down and automatically moves to the next exercise when it reaches 0. You can cancel the timer early if you wish by pressing BTN2. If it is the last set of an exercise, you don't need to rest, so it lets you know you have completed all the sets in the exercise and can start the next exercise.

+      Enter in your weights for each exercise, start light and keep consistent with your training. The weight increment field is how much the app will increase your weights for an exercise if you successfully complete all the reps and sets for an exercise. Make sure its a value that matches the weights in your gym.

+This clock tells time in very rough approximation, as in "Late morning" or "Early afternoon." Good for vacations and weekends. Press button 1 to see the time in accurate, digital form. But do you really need to know the exact time?

+ * Escope (<a href="http://github.com/estools/escope">escope</a>) is an <a

+ * scope analyzer extracted from the <a
+ * href="http://github.com/estools/esmangle">esmangle project</a/>.
+ * <p>
+ * <em>escope</em> finds lexical scopes in a source program, i.e. areas of that

+ * variable. With each scope the contained variables are collected, and each
+ * identifier reference in code is linked to its corresponding variable (if
+ * possible).
+ * <p>
+ * <em>escope</em> works on a syntax tree of the parsed source code which has
+ * to adhere to the <a
+ * href="https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API">
+ * Mozilla Parser API</a>. E.g. <a href="http://esprima.org">esprima</a> is a parser
+ * that produces such syntax trees.
+ * <p>

+# Settings
+
+This is Bangle.js's settings menu
+
+* **Make Connectable** regardless of the current Bluetooth settings, makes Bangle.js so you can connect to it (while the window is up)
+* **App/Widget Settings** settings specific to installed applications
+* **BLE** is Bluetooth LE enabled and the watch connectable?
+* **Programmable** if BLE is on, can the watch be connected to in order to program/upload apps?
+* **Debug Info** should debug info be shown on the watch's screen or not?
+* **Beep** most Bangle.js do not have a speaker inside, but they can use the vibration motor to beep in different pitches. You can change the behaviour here to use a Piezo speaker if one is connected
+* **Vibration** enable/disable the vibration motor
+* **Locale** set time zone/whether the clock is 12/24 hour (for supported clocks)
+* **Select Clock** if you have more than one clock face, select the default one
+* **HID** When Bluetooth is enabled, Bangle.js can appear as a Bluetooth Keyboard/Joystick/etc to send keypresses to a connected device. **Note:** on some platforms enabling HID can cause you problems when trying to connect to Bangle.js to upload apps.
+* **Set Time** Configure the current time - Note that this can be done much more easily by choosing 'Set Time' from the App Loader
+* **LCD** Configure settings about the screen. How long it stays on, how bright it is, and when it turns on.
+* **Reset Settings** Reset the settings to defaults
+* **Turn Off** Turn Bangle.js off

- * Escope (<a href="http://github.com/estools/escope">escope</a>) is an <a
- * href="http://www.ecma-international.org/publications/standards/Ecma-262.htm">ECMAScript</a>
- * scope analyzer extracted from the <a
- * href="http://github.com/estools/esmangle">esmangle project</a/>.
- * <p>
- * <em>escope</em> finds lexical scopes in a source program, i.e. areas of that
- * program where different occurrences of the same identifier refer to the same
- * variable. With each scope the contained variables are collected, and each
- * identifier reference in code is linked to its corresponding variable (if
- * possible).
- * <p>
- * <em>escope</em> works on a syntax tree of the parsed source code which has
- * to adhere to the <a
- * href="https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API">
- * Mozilla Parser API</a>. E.g. <a href="http://esprima.org">esprima</a> is a parser
- * that produces such syntax trees.
- * <p>
- * The main interface is the {@link analyze} function.

+# Camera shutter
+
+Control the camera shutter from your phone using your watch
+
+## Usage
+
+1. In settings, enable HID for "Keyboard & Media".  
+2. Pair your watch to your phone.  
+3. Load your camera app on your phone.
+4. There you go, launch the app on your watch and press button 2 to trigger the shutter !
+
+## How does it work ?
+
+The app uses HID to send the key "Vol +", which is a shortcut for camera trigger on Android and iOS.
+
+## Creator
+
+Paul Charlet, using code from HID music app.
