Verdict
Square Appointments is built for booking and payments together, not just calendar viewing—reviewers praise the client-facing scheduling and automated reminders, but there's a real pattern of crashes, freezes during payment, and dark mode bugs.
Best for
A solo service provider, like a one-person barber or salon operator, who needs clients to self-book and pay in the same app and doesn't mind occasional glitches during a transaction.
Dealbreaker
Multiple reviewers report the app freezing specifically when taking client payment, plus dark mode rendering it nearly unusable and updates that have broken existing workflows.

Where we recommend it
The best calendar apps ›Calendar apps that are well rated and still maintained, with the reason you might not want each.
Alternatives with the same rule.
Every app here is rated 4.2 or better, has been updated in the last eighteen months, and has no significant number of reviewers reporting it broken. Price is not the rule on this list — some are free, some are not. Also with a catch.

Verdict. The built-in Calendar is a solid default, but recent reviews show recurring complaints about alerts not firing and events not syncing across devices, which is a serious problem for a scheduling app.
Best for. An iPhone user who lives entirely in Apple's ecosystem and mainly needs a simple, no-frills calendar without cross-platform sync demands.
Dealbreaker. Multiple reviewers report notifications and reminders silently failing to trigger, and events not syncing correctly across devices, sometimes with lost events.
Free · 4.8★ (398,682) · Updated Aug 31, 2026
Verdict. Cozi is a shared family calendar built for coordinating multiple people's schedules, with real-time sync and reminders that families lean on for years. Some users report freezing and a few glitches with shared lists, and a chunk of the useful features sit behind a yearly subscription or ad-supported free tier.
Best for. Parents juggling kids' activities, appointments, and shopping lists across multiple phones who need everyone notified the moment something changes.
Dealbreaker. Importing an existing calendar isn't supported even on the paid Gold tier, and some reviewers report the app freezing when adding events.

Verdict. Dayforce is a workplace HR/payroll app for clocking in, checking pay stubs, and viewing schedules, not a personal calendar app. Reviewers report crashes during punch-in, slow loading, and sync mismatches with the desktop version.
Best for. An employee whose company already uses Dayforce for timekeeping and payroll who needs to punch in, check pay stubs, or view a work schedule from a phone.
Dealbreaker. This isn't a general calendar app: reviewers describe crashes and freezing specifically during time clock punch-in, slow loading causing punch errors, and schedule/calendar data not syncing reliably with the desktop version.
