Tides shift constantly and vary by location. Spuitgat is a classic-style tide clock that works anywhere, even in remote areas without tide stations or subscription-based data feeds. There are no recurring costs. Spuitgat doesn’t rely on internet access or external data. Instead, you set the time of the last known high or low tide, and it calculates tide predictions for the next few days, after which it needs to be recalibrated to stay accurate. Designed with clean visuals and simple functionality, Spuitgat is ideal for keeping an eye on the tides while you relax on holiday. Disclaimer: Spuitgat provides a rough estimate of the tides and is intended for casual, recreational use — like planning a beach trip. It’s not accurate enough for navigation, safety-critical decisions, or professional use.
