Description

Pebble Tides shows the day's tides at a glance: a graph of the high and low tides with their exact times and heights, the current water level, whether the tide is rising or falling, and optional mid-tide times. It uses your location to pick the nearest tide station and keeps working offline by caching a week of predictions, or pin a region ahead of a trip to cache up to 45 days across a whole area.

Features:
- Uses your location to pick the nearest tide station
- Daily tide graph with high/low times and heights
- Current level with a rising/falling indicator
- Optional mid-tide times (off by default)
- Sunrise and sunset night shading
- Step through tides with the buttons; long-press to jump a day, Select to jump to now
- Feet or metres, 12 or 24 hour clock, all set from the phone
- Caches a week of predictions and refreshes once a day; works with the phone out of range
- Pin a region for an upcoming trip: download up to 45 days for every station within a chosen radius, then see the nearest one offline as you move
