Some Casio watches have the ability to show moon and tide graphs. Unfortunately the software of the watches needs localized data. In newer CASIO wrist watches like the G-Shock GW-7900 you only have to input the next high tide time of your area. But in older models you need the lunitidal interval for tide prediction. This android app helps you to find the lunitidal interval (INT) for your CASIO tide graph wrist watches.
Following countries are supported at the moment:
Costa Rica (east)
Papua New Guinea
United Arab Emirates
Please give me a feedback.

The algorithm is based on a world map of tidal harmonic constituents with a 0.04° resolution and a tide prediction mode assuming 2 highs and 2 lows per 24 hours:
lunitidal interval INT = Greenwich Interval GI + longitude/15° | >0
The accuracy of INT for a casio wrist watch is about +/-1 hour.
This app has no spyware/trojaner/virus inside.
There is no background activity meaning less battery consumption.
The app gets the local position only via your mobile provider or GPS.
