# PebblePacer

A fork of WayeM’s Allure

A workout app for the **Pebble Time 2** (platform `emery`): walk, run or train
with your heart rate shown live in five color-coded effort zones.

While this app doesn’t use GPS, with customized stride lengths that match your phone’s health app stride lengths, you can get very close to your actual distance. I tested this out with customized stride lengths and compared it to my phone’s calculated distance which used GPS and the distance was within 1.85% :)

## Features
- Three activities: walk, run, workout, with a 3-second countdown.
- Live heart rate. The top half of the screen changes colour with your effort
  zone (five zones, as a percentage of your estimated maximum heart rate).
- Duration, steps, distance, and pace. Press the down button to switch.
- Session summary: average and maximum heart rate, estimated calories.
- Settings on the phone: sex, age, height, weight, and running and walking stride length
- The language follows the watch language: English, French, German, Spanish,
  Italian and Portuguese.

## How the numbers are computed
- Maximum heart rate: Tanaka formula (208 - 0.7 x age) for men, Gulati formula
  (206 - 0.88 x age) for women.
- Zones: Set your own zones or use a calculation that uses percentages of your max heart rate for your age (below 60 %, 60-70 %, 70-80 %, 80-90 % and 90 % or more of that maximum)
- Calories: Keytel formula, from average heart rate, weight, age and sex.
- Distance: Set your own stride length or use an automated calculation. Check your phone’s health app and select mobility to see your average walking stride and running stride. There is no GPS, so distance and pace are estimates.

## Settings
Open the app in the Pebble mobile app and tap the gear icon. Values are stored
on your phone and on your watch. Until you save them once, defaults are used.

## Status and limitations
- Tested on a Pebble Time 2 and in the emulator.
- Metric or Imperial units
- The German, Spanish, Italian and Portuguese texts were written with
  assistance and have not been reviewed by native speakers: corrections are
  welcome.

## RunZone changes
- Running-focused display with elapsed time, live heart rate, heart-rate zone, and stride-based distance.
- Running stride length is configurable in the phone settings (40–200 cm).

**I’m now experimenting with the a version of the app that will try to get more accurate by checking the phone’s GPS and if it doesn’t detect the phone, it will use either the automated or manual stride length. To experiment with me, try Pebble Pacer GPS and provide feedback. Thanks!
