SyncGene
SyncGene synchronizes your data automatically*, so you can keep your Contacts and Calendar events in sync and up to date across all of your accounts. You just need to add at least 2 sources you want to sync (Google/Exchange/iCloud). The changes, which you make in one source, will be automatically transferred to another without any duplicates. You can share the latest information from your address book or calendar with other people. Merge your personal information from various places. We'll unify this information into one synced view of one Calendar, one Address Book and one To-do list for your hassle-free management. No more lost, duplicate or incomplete entries. Manage and update your events, contacts and tasks from any connected device, service or app.

SYNCDATE
SYNCDATE is a web application for two-way Google Calendar synchronization. Connect multiple Google accounts, select which calendars to sync, choose direction (one-way or two-way), and SYNCDATE keeps events aligned automatically in the background.

- Sync health monitoring — See sync status, freshness, latency, error summaries, and deterministic fix steps from the dashboard.
- Clean exit — Delete a sync process and optionally remove all events it created. Reversible and traceable.
- Webhook-driven with polling fallback — Events sync within seconds via push notifications, with 15-minute polling as a safety net.
