Rainfall reads how your day is landing — and meets you with one quiet, well-chosen practice, before you have to ask. No check-ins to remember. No scores. Just support when the weather turns.
Free to try. On-device. On the App Store for iPhone — Mac coming soon.
From the shape of your day — a short night, a packed calendar, a restless heart — Rainfall infers how you're feeling and reflects it back as weather. It always shows its working, on your iPhone. A tap tells it when it's read you wrong.
For whatever it read, Rainfall has something already waiting — a breath, a short meditation, a reflection, or a rainfall soundscape for sleep. And it never lets you forget the kind part: feelings are weather, and weather passes.
Your weeks become a serene climate — gentle trends, clear-sky stretches shown as atmosphere, never a streak to lose. “You've met the morning 12 days.” However today goes is okay.
Each one for a different kind of moment — a timbre, a pace, a presence. Pick the voice that fits, or let the read choose for you. Synthetic by design, shaped in ElevenLabs for Rainfall specifically.
Your Mind Weather, your notes, your climate — all of it stays on your iPhone. Nothing is uploaded, sold, or used to train anything. There's no account to make. We keep the light on; we don't keep your data.
Everything is computed locally.
Open it and begin.
Zero third-party analytics.
Rainfall is independent software, built and supported by one person. The Heirloom License is how that becomes a strength, not a risk you have to take on faith.
I'm Alan. For 25+ years I've built and led digital product teams — at Target, lululemon, Dollar Shave Club, Quip, and Munchkin among others — shipping software used by millions. Rainfall is the work I want to be doing now: something quiet, kind, and built to last.

Rainfall is licensed under the Heirloom License — variant HL-1.0-MPL2.0-12mo. If Rainfall is ever truly abandoned — twelve months of silence with no answer to a good-faith support request — the full source code automatically opens under MPL-2.0. Forever. The promise is in the license; a dead-man's switch in the repo delivers it.
