SyncString is being built to keep the people and plans in your digital life aligned across iCloud, Google, and Microsoft 365—without ActiveSync.
Private beta for individuals and invited organizations. Connector setup varies by provider.
Made for life between ecosystems
SyncString handles the complexity between providers while keeping you in control of every connection and change.
Provider-aware sync
Review contacts and calendar events across your connected accounts before SyncString applies any provider-side changes.
Source-aware cleanup
SyncString tracks where every managed copy came from, so you can preview and remove only the right records when an account disconnects.
One clear view
Search events across providers, organize managed records with Smart Labels, and preview availability rules before enforcement is enabled.
Control is a feature
Every managed copy keeps its source identity. Before changes or cleanup, SyncString shows you exactly what will happen.
How it works
Authorize the accounts you already use.
Pick the calendars and contacts you want aligned.
Preview changes, then keep everything current.
SyncString for teams
Give people a clearer way to work across providers while giving invited organizations a path to oversight, policy, and cleanup controls as tenant onboarding opens.
