Can't find your Pebble? If it is still within bluetooth reach and your phone/pad is connected to your watch, installing this app will make your watch vibrate and flash.

The app counts minutes and seconds until the watch is found. You can set vibrations and screen flashing on or off.

Hint: play hide-and-seek by hiding the watch and using a phone to find it.

APP MESSAGE THAT CAN ONLY BE VIEWED ON YOUR PEBBLE TIME

IMPORTANT: Version 1.0.0 of the Android app will stop working before October 2026. Update it to 1.1.0 before then, or you won’t be able to recognize any songs!

A song-finding app using Shazam’s audio recognition. It connects to an Android companion app to listen to nearby sound through your phone’s microphone, securely process it through Shazam’s service, and match it with any known audio signature in Apple’s music catalog. 

You can install the Android app from the source link at the bottom of the page. After setting it up on your phone, launch the watch app at any point to listen for music. When a song is successfully found, you will feel a short vibration and be presented with the song name and artist (currently, only names with Latin letters are known to display correctly). The previous 10 found songs are saved right on your watch, organized by discovery date.

Remember the old days, when your digital watch would come preloaded with a bunch of cities throughout the world, and a world map prominently displayed on the screen? Wasn't it fun to just scroll through all those cities, wonder where all those abbreviations really were?

That's why I created TIME TRAVELER, a fun, animated world time experience for the Pebble watch! Smoothly animates between cities around the world, showing real-time day/night data, accounting for time zones, summer time, and more!

Features:
- Real-time daylight terminator calculation, showing you exactly which cities are experiencing daylight and which aren't!
- Hide or show your favorite cities, selecting from 49 different cities commonly found on Casio™ digital world time watches!
- Shows you whether it is today, tomorrow, or yesterday for a given time zone -- now you can finally remember what day it is for your friends in Asia!
- Exciting animations!

Notepad allows you to take notes directly on the Pebble! Using Tertiary Text it is possible to quickly type complete and full messages directly on your Pebble. 

Visit the site for more information on how to type with it. The keybindings become muscle memory in no time.

To people with older pebbles:

There are two new options, one is to Enable experimental mode were we maximise sending speed of the map, but that can lead to instability, together with the telemetry option I hope i can make sure the update works fine on ever watch. When im sure it works fine with every watch model, i want to remove the telemtry again. I only could test this on my time 2 but the emulator behavior and hw behavior is different.

If you have any suggestions or issues send me a message using the contact developer option or open a issue on github.

(This is based on the 2.0.1 version of the PebbleBucks app by Alexsander Akers. His 3.0 version is currently not working for a large group of users, so I'm putting this modified/fixed version of 2.0.1 up for people to use in the interim.)

Sitting still for long periods of time can be detrimental to your health. This app reminds you to stand up and move around to keep you happy and healthy.

It's ideal for those of us who work at a desk all day.

Features:
* Scheduler so you only get reminders when you want
* Motion detection to track when you've been stationary too long
* Snooze to pause reminders if not convenient (if you're at lunch or in a meeting, for example)
* NEW: Configurable vibration strength

Once the schedule and motion detection are set then there's no need to do anything more - the app works automatically.

IMPORTANT:
* If using the motion detect feature be sure to tell the app which wrist your watch is on.
