Cycle tracking, reimagined
A private, ad-free cycle tracker that maps the phases of your cycle to seasons and tides — so the rhythm finally makes sense.
Why Tide
Tide was built on a simple belief: information about your body belongs to you, and only you. That principle shapes every decision in the app.
Your data lives on your device first. Nothing is sold, ever, and there is no advertising of any kind inside Tide.
Tide speaks to you and your body — never assumptions about who you are. The language stays human throughout.
Tide launches completely free. No paywall, no locked features, no subscription required to understand your own cycle.
The rhythm
Numbers and charts can feel clinical. Tide translates the phases of your cycle into something intuitive — the turning of seasons, the rise and fall of water.
The quiet, inward phase. Rest is the work.
Energy returns. The water comes back in.
The fullest, most outward stretch of the cycle.
Winding down. The water draws back out.
Our promises
Not to advertisers, not to data brokers, not to anyone. Your cycle is not a product.
There is no ad SDK in Tide. Opening the app will never mean being sold to.
Anything free at launch stays free. We don't take things away later.
Tide is for anyone with a cycle. The language reflects that, always.
Our story
“Tide started with a frustration: every tracker I tried felt like it was built to mine me, not help me. I wanted something quiet, honest, and built around how a body actually feels — not a spreadsheet of someone else's assumptions.”
— Annie, founder of Zenkolabs
