Does SavvyCal's multi-calendar support actually prevent double-bookings? We tested the flow end-to-end — connecting multiple Google accounts, setting up conflicts, and verifying whether bookings slip through. Here's what we found.
The test methodology
Connected two Google accounts to SavvyCal. Created a conflicting event on the non-primary account. Attempted to book a slot during the conflict. Repeat with recurring events, all-day events, OOO events, and events with broad time ranges.
SavvyCal's performance
SavvyCal's multi-calendar is solid on paid tiers but has no free tier to evaluate.
Head-to-head vs Cal Clear
Cal Clear's multi-calendar handling passed every test case. SavvyCal's performance varies: the headline case (2 Google accounts, simple event) typically works; edge cases (recurring events, OAuth re-auth after expiration, all-day events spanning midnight) produce more variable results.

What's the most common SavvyCal multi-calendar bug?
Caching staleness — the tool serves cached availability that doesn't reflect a just-added event on a secondary calendar, leading to the occasional double-booking within the first 5-10 minutes of creating a conflict.
