One App to Plan Your Entire Life

whatday.ai was born from a simple frustration: too many apps, too many subscriptions, too many logins. We built one platform that does it all — and we made it free.

The Problem We Solve

The average person uses 5–7 different apps just to manage their day: a calendar here, a to-do list there, a budget tracker somewhere else, a project board in another tab. That's fragmented, expensive, and exhausting.

whatday.ai replaces them all. Calendar, tasks, projects, budgets, bills, goals, documents, spreadsheets, weather, fitness tracking, meal planning, and 20+ more plugins — all in a single, fast, beautifully designed platform that works on any device.

What Makes Us Different

Free Forever

Our free tier is genuinely generous — 30+ plugins with no time limits, no credit card, no catch. Most people never need to upgrade.

Pro from $1/month

When you do upgrade, we reward you for being early. The first 12,000 Pro users pay just $1/month — locked in forever. Your price never increases.

Plugin Ecosystem

Enable only the plugins you need. From budget tracking to martial arts training, from biblical calendars to weather forecasts — whatday.ai grows with you.

Built for Speed

Built with Rust — one of the fastest programming languages in existence. Pages load instantly. No bloat, no lag, no Electron wrapper. Pure performance.

Privacy First

Your data is yours. We don't sell your information, we don't mine your calendar, and we don't spam your inbox. Simple as that.

Works Everywhere

Desktop, tablet, phone — whatday.ai works beautifully on any screen. No app download required. Just open your browser and go.
