SyncString reads contacts and calendars across iCloud, Google, and Microsoft 365, then writes confirmed changes back to Google and Microsoft so native apps stay useful.
Private beta for individuals and invited organizations. Connector setup varies by provider.
Made for life between ecosystems
SyncString brings provider reads, contact indexing, itemized write previews, backup context, and run history into one clear workspace.
Provider sync
Read across iCloud, Google, and Microsoft, then preview confirmed contact and calendar writes to Google and Microsoft.
Duplicate review
Index contacts by explicit opt-in, detect likely duplicates, and review comparison previews without executing a merge.
Deliberate changes
Create encrypted backups, review itemized changes, and delete only calendar events you explicitly select.
Control is a feature
Each result keeps its provider identity. SyncString shows what was read, what may change, what was confirmed, and how each provider responded.
How it works
Authorize the accounts you already use.
Review the exact contacts and calendar events that may change.
Apply selected Google or Microsoft changes and inspect every result.
SyncString for teams
Give people a clearer way to review provider data while invited organizations manage provisioning, roles, audit history, and beta access.
