Quick answer: Reclaim is worth evaluating if you want automated scheduling alongside calendar sync. OneCal is worth evaluating if calendar copying, a combined view and booking links fit your work. SYNCDATE is another option for supported copying arrangements, including a permanent small Free plan. Choose by the calendars and behavior you need, not a blanket fastest-or-cheapest verdict.
What you are comparing
Reclaim's pricing, checked October 6, 2026, describes scheduling features such as tasks, habits and focus time. Lite is free and lists one Calendar Sync; Starter lists three. If you use those scheduling capabilities, evaluate the bundle rather than pricing sync in isolation.
OneCal's pricing, checked October 6, lists Google, Outlook, iCloud and CalDAV synchronization, a calendar view and booking links. Its annual Starter, Essential and Premium tiers list $5, $10 and $25 per user per month for 2, 5 and 50 calendars. A 14-day trial is different from a permanent free plan. Check billing cadence and current features before purchase.
| Your main job | What to evaluate |
|---|---|
| Find time for tasks or habits around commitments | Reclaim's scheduling behavior and account support |
| Keep copies across calendars and use booking links | OneCal's provider, copying and booking settings |
| Keep permitted copies across supported accounts | SYNCDATE's direction, privacy and arrangement limits |
| Only see calendars together | Your calendar app's native combined view |
| Include personal commitments in Outlook work availability | Microsoft's native option in our method guide |
CalDAV is not a unique SYNCDATE differentiator: OneCal's current pricing page also lists it. Check the specific service, authentication method and required behavior before assuming generic provider labels establish compatibility.
When SYNCDATE fits
The Free plan includes two accounts, two participating calendars, one sync and a 30-day future window. Plus adds capacity but allows at most four calendars in one Mirror or ten in one Push. Pro allows five in one Mirror or twenty in one Push, a longer future window and appearance settings for individual destinations. Total plan allowances are a different limit from a single arrangement.
For example, five calendars in one Mirror need Pro. A simple two-calendar job can fit Free. A larger plan will not fix missing write permission, provider approval or an incorrectly selected destination.
Use the Google–Outlook recipe, two-Outlook guide or multiple-Google guide for the accounts you actually have. If access is shared or controlled by another organization, get permission first.
Privacy and timing need verification
SYNCDATE's presets have different field choices. Personal-to-work starts with masked titles and omitted private fields. Google–Outlook two-way starts with original titles, descriptions and locations enabled. Read the appearance settings, choose what may cross, and inspect the copy before relying on it. A masked title does not by itself make an event count as Busy.
Provider notifications help prompt SYNCDATE updates, but delays and retries can occur. We have not run comparative provider timing tests for these services. A vendor's real-time wording is not a guaranteed maximum delay or proof that another product is slower.
Switch without running two writers on the same calendars
Do not run the old tool and a replacement on the same production calendar pair for a day. Two independent tools can each treat the other tool's copies as new source events. SYNCDATE's handling of its own copies is not a promise that it recognizes another service's copies.
- Record your source calendars, destinations, directions, filters and date window. Review which original calendars own each commitment and which entries are copies.
- If possible, test the replacement using separate empty calendars and harmless events, with no guests. Confirm permitted write access and review the title, description, location and availability settings before starting. Creating a sync can also copy existing eligible events.
- Read the old service's current disconnect instructions. Confirm whether stopping or deleting a connection removes its copies or leaves them behind. Plan any cleanup before touching production calendars; do not delete original commitments or assume a cancellation cleans up copies.
- Stop the old service from writing to the production pair before enabling the replacement on that pair. Inspect the remaining calendars and resolve old copies according to the vendor's instructions. If ownership is unclear, ask support before bulk cleanup.
- Enable the replacement, then create, move and delete a harmless original event in each direction you need. Inspect the actual destination calendar, including its Free/Busy status. Check the scheduling or booking view you depend on before retiring the old service.
The aim is a verified handover. Timing and copy cleanup vary by provider and service; there is no universal zero-gap switch procedure. If your organization requires administrator approval, use the workspace access guide and get that approval rather than changing direction to bypass it.
Choose the smallest arrangement that does the job
List each original calendar, the destinations that need its commitments and the settings each destination needs. Evaluate native options first when they meet the job. Then compare the plans and verify a harmless example. Keep a free arrangement if it fits, and pay only for capabilities or limits you actually need. The full comparison covers the wider shortlist.
Frequently asked questions
Does OneCal only support Google, Outlook and iCloud?
Its pricing page checked October 6, 2026 also lists CalDAV. Verify the specific service and authentication requirements with OneCal rather than assuming a generic provider label proves compatibility.
Is a larger plan always necessary?
No. Start with the actual account, arrangement and future-window limits. Native options or a small free setup can meet the job. Verify the chosen setup before expanding.
