I make small, honest Android apps for people who love the outdoors. They're free, open source, and have no ads, no tracking and no accounts. Your data stays on your phone.

SwellCheck

Surf and sea kayak conditions at a glance, with a home-screen widget:

• Surf rating (Flat to Epic) and a paddling call (Go / Marginal / No go) based on limits you set yourself
• Wind, gusts, swell height, period and direction, with an offshore-wind warning
• Tides drawn to scale, with high and low times and the range of each tide
• Spring and neap strength and the moon phase, worked out on your phone
• A 72-hour outlook for the sea and the wind, side by side

Works without Google services, so it runs happily on /e/OS, GrapheneOS and other de-Googled phones. Source code

More apps on the way.

Why donate?

There are no ads and no data selling, so your support is the only thing funding this work. It pays for my time fixing bugs, keeping up with Android updates and building new features.

The price of a coffee now and then makes a real difference. Thank you, and see you on the water. 🛶
