A calendar that works for you.
Every account in one place. Built privacy-first for GrapheneOS and de-Googled phones — no Google Play Services required — and just as at home on any Android or iPhone. Here's the full tour.
Your day, at a glance
Open CalyFly and see exactly what matters now — a clean overview of everything scheduled today across all your calendars, plus quick tasks, notes and links for the day.
- Unified view of Google, Microsoft, CalDAV & local events
- One-tap quick add — plus optional AI Quick Add
- Alerts & reminders with haptics so you never miss a thing
The week ahead, organized
Scroll a continuous, grouped timeline of what's coming up. Events, local entries and rich link previews live together — so a concert ticket or venue page shows its banner right in the card.
- Grouped by day, infinitely scrollable
- Inline link-preview banners for events
- Smart location suggestions when you add a place
More than just events
Not everything is a meeting. Jot a quick note, keep a running list, or add a task with a due date — CalyFly keeps them right alongside your day, so your groceries and your 3 pm call live in one place.
- Tasks, notes & multi-item lists, each with a due date
- Pinned to the day on both Today and Agenda
- Fully local and private — no account required
Dress it your way
From a crisp, professional light theme to a power-sipping True Black for OLED screens — CalyFly looks great and feels native on any device. Free, always.
Go premium: Mint Noir, Atlantic Blue & Neon
Hand-crafted, gradient-lit themes with depth that makes your day pop — from near-black mint and oceanic aurora to vivid cyberpunk neon. An optional in-app upgrade; every core theme stays free, always.

Your day, before you even open the app
Pin the CalyFly widget to your home screen and today's events, tasks and notes are right there at a glance — tap any item to jump straight in. Here it is on iPhone:
Built thoughtfully, end to end
Accounts that just connect
Google, Microsoft 365 and any CalDAV server (Nextcloud, Fastmail, iCloud-style) — alongside fully local, on-device calendars.
Smart, private locations
Type a venue and CalyFly finds the real address — even tricky ones — without handing your location to a big ad network.
Rich link previews
Drop a link on an event and its banner appears right in the card — perfect for tickets, venues and invites.
Reminders that respect you
Local notifications and alerts with vibration. No cloud push, no account required, no leaks.
Real invites
Send standards-based calendar invites to attendees — self-hosted and under your control.
FOSS & transparent
Free and open source. No analytics SDKs, no dark patterns — just software that's on your side.
GrapheneOS-first
Designed for hardened, de-Googled phones like GrapheneOS — no Google Play Services needed. Privacy-conscious from the start, and available to every Android and iPhone build.
Intelligence, on your terms
That AI Quick Add button turns a quick sentence into a fully-formed event, suggests real venues as you type, and can even draft your notes — built to run privately. AI features are an optional in-app purchase, so you only pay if you want them. Every calendar, view and theme in CalyFly is free — and always will be.
