Prices and features as shown on each product's website in October 2026; check them for current details. OneCal and CalendarBridge are broader scheduling suites, and the multi-way sync they offer is genuinely useful if you need to keep several calendars equal.
When calendarnexus is the right pick
- You want Outlook to appear in Google, and nothing else to change.
- You want it in real time, not within a day.
- You do not want another account, another app or another dashboard.
- You would rather pay 70p than a fiver for a single feature.
When it is not
- You need several calendars across several accounts kept in step with each other.
- You need booking pages or a unified calendar view.
- A day's delay is fine, in which case Google's free subscription is all you need: see how to set it up.
