Proton Calendar
Pros
- Event metadata is designed for zero-access encryption on Proton’s infrastructure
- No ads or third-party trackers in the product’s privacy positioning
- Same Proton Account ties calendar, mail, VPN, drive, and pass for one subscription story
- Web plus iOS and Android clients cover typical mobile-and-browser workflows
- Swiss jurisdiction and open-audit culture matter for security-sensitive teams
Cons
- Feature depth and polish still trail Google Calendar for power schedulers
- Store reviews cite sync latency, missing niceties, or occasional logout bugs
- Deep Google Workspace or Microsoft org cal coexistence is not the primary design center
- Native desktop clients are not the headline—browser access carries most laptop use
- Meaningful calendar limits on the free tier push heavier users toward paid bundles
Fantastical
Pros
- Natural-language event entry still sets the bar many competitors chase
- Calendar sets and focus filters tame noisy multi-account weeks
- Deep hooks for Exchange, Google, Zoom, Webex, and similar meeting stacks
- Flexibits Scheduling cuts email ping-pong for external openings
- Cross-device polish spans Mac, iOS, watchOS, visionOS, and Windows for subscribers
Cons
- Premium power features sit behind Flexibits Premium rather than a single cheap unlock
- No Android app in Flexibits’ own platform list—Android-first users look elsewhere
- Team pricing and SSO land in mid-market territory versus free calendar defaults
- Cardhop bundling matters less if you only wanted a calendar replacement
- Windows parity arrived later; edge-case gaps still surface in forums
