# Seaside utility watch

A watch that does just what I want when I am at the seaside, showing day, date, month, year, sunrise, sunset, location and approximate high and low tide times.

Touch to toggle between sunrise / sunset and tide times.

Very much a work in progress. Sunrise/set requires location to have already been set in mylocation.json using MyLocation app.

DO NOT RELY ON THESE TIDE TIMES! This is in development.

When working, you will set the next tide time (high or low) in application settings, the watch will then calculate approximate next tide time by adding 6 hours and 12 minutes to the tide time and keep doing so until reset.

This may become very unreliable over time and will need periodic realignment.

## Many faults

- [ ] high and low getting muddled on rollover?
- [ ] tide set to 'false' instead of high/low
- [x] minutes not appearing in settings


## Many of the to-dos

- [ ] handle tide time not being set and remove default time which is just for testing
- [ ] write tide data back to json file when flipped to keep it up to date when app reloaded
- [ ] tidy up code in general
- [ ] no need to check sunrise and sunset times so often
