SyncCal vs OneCal
SyncCal vs OneCal: Which Calendar Sync Tool to Choose
Side-by-side comparison of SyncCal and OneCal for calendar synchronization across Google, Outlook, Apple, and Calendly. Pricing, two-way sync, privacy, and platform coverage.
Verdict
SyncCal is cheaper at the Pro tier, supports CalDAV (which OneCal does not), and matches OneCal feature-for-feature on the core sync engine. OneCal has a longer track record. Pick SyncCal if you need Apple iCloud or CalDAV, or want a lower price; pick OneCal if you only sync Google and Outlook and prefer the longer history.
Side by side: SyncCal vs OneCal
| Dimension | SyncCal | OneCal |
|---|---|---|
| Starting Pro price | 2.99 USD per month | 5 USD per month |
| Apple iCloud and CalDAV support | Native CalDAV with app-specific password | Not supported as of 2026 |
| Calendly conflict-calendar pattern | Built-in title rewrite to keep details private | Title rewrite available, requires manual rule |

| Free tier | 2 calendars, 50 syncs per month | Limited trial only |
When SyncCal wins
You sync at least one Apple iCloud or CalDAV calendar. OneCal does not support CalDAV in 2026, so SyncCal is the only option in that scenario. You also save roughly 24 USD per year on the Pro tier.
When OneCal wins
You only sync Google and Microsoft, you have been on OneCal long enough that switching has migration cost, and you do not need CalDAV. The feature gap is small in that scenario.
What is the same
Both products use OAuth 2.0 for Google and Microsoft, both offer two-way sync, both let you filter mirrored events, both run as managed SaaS with no self-host option, and both encrypt data in transit and at rest.
What is genuinely different
Pricing (2.99 vs 5 USD/month on Pro), CalDAV support (yes vs no), and free-tier generosity (2 calendars + 50 syncs/month vs trial only). Pick on whichever of those matters to you.
Adjacent comparisons
- SyncCal vs Calendly: different category. Calendly is a scheduler, SyncCal is a sync engine. Most teams run both.
- SyncCal vs Reclaim: Reclaim is an AI scheduler with a limited sync feature. SyncCal is sync-first.
If your CalDAV requirement comes from iCloud specifically, the dedicated Sync iCloud Calendar with Outlook and Sync iCloud with Google pages have the platform steps.
Frequently asked questions
Is SyncCal cheaper than OneCal?
Yes. SyncCal Pro starts at 2.99 USD per month versus OneCal Pro at 5 USD per month as of 2026. Both unlock unlimited calendars at the Pro tier.
Does OneCal support Apple iCloud?
Not as of 2026. OneCal connects to Google and Microsoft accounts. SyncCal supports Apple iCloud via CalDAV with an app-specific password, plus any other CalDAV server.
Can I migrate from OneCal to SyncCal without losing my sync rules?
You will need to recreate your sync rules in SyncCal, but the setup takes under five minutes per calendar pair and SyncCal will import existing event mappings on the first run so duplicates are avoided.
Which tool is better for Calendly users?
Both can mirror events into the calendar Calendly checks. SyncCal includes the title rewrite to Busy by default; OneCal requires you to set it up manually. For Calendly users the workflows are equivalent once configured.
