Estran : Marées de ta Plage, from Grillons Apps, is a mobile tide reference designed for coastal planning and on-site decisions. The app calculates localized tide times and heights for beaches rather than relying on nearby ports, and it displays countdowns, a 24-hour height curve, and celestial times. Targeted at shore fishermen, surfers, sailors, and casual beach walkers, it aims to give precise, pocket-sized tidal information that works without a network connection.

How it fits into a beachgoer's daily routine

Estran places tide timing at the center of short excursions, showing whether the sea is rising or falling and providing countdowns to the next high and low tides. The app presents a 24-hour interactive height curve so users can swipe to inspect times and heights, and it supplies sunrise, sunset, moonrise, and moonset times to help schedule outings around light and lunar phases.

Can you trust its calculations away from signal?

The app runs calculations locally because of a serverless architecture that lets it operate entirely offline. It uses harmonic components and the SHOM method, with coefficients referenced to Brest, to compute tides on the device. Predictions are astronomical by design; actual sea level can still be affected by local weather, a limitation the app notes when presenting forecasted heights.

Does it integrate with mobile workflows and location services?

Designed for mobile use, the app supports GPS-based beach detection, including unnamed coastal spots, and it offers home screen widgets on supported platforms to surface tide info at a glance. Alerts can be personalized for specific events or coefficients, and the developer avoids account requirements so setup is minimal for users who want quick access on a phone.

Is privacy respected and how do users view it?

Privacy is a stated priority: the developer declares zero data collection, no tracking, and an ad-free interface. That stance underpins the app's appeal to people who want simple, private tools for coastal activities. User reception highlights simplicity and reliable offline calculations, which reinforces the app's suitability for frequent shore use.

To sum up, a practical choice for regular coastal users

To sum up, Estran : Marées de ta Plage is a solid option for shore fishermen, surfers, sailors, and casual beach walkers who need dependable, local tide timing in everyday planning. It suits habitual checks before leaving for the shore, but users who require meteorological adjustments from dedicated weather services should consult complementary sources. Pro tip: make tide checks part of your pre-departure routine to integrate timing into short trips.
