Hardware gauges

Tide Alerts the app shows data from Sentient Things hyperlocal gauges and from public networks. The physical tide gauges (solar, cellular) are sold separately. They are not an in-app purchase.

The free app still works for public stations if you never buy hardware.

For hardware sales and fulfillment, use the Sentient Things shop / sales contact (sales@sentientthings.com) — not this help site’s GitHub editor, and not the Shopify privacy URL as a support page.
