Turns your existing Android contacts into a lightweight personal CRM with interaction logs, follow-up reminders and birthday alerts, no new account or cloud lock-in, and no telemetry.

FreeWorks offlineOpen sourceNo ads
What to know
How it works
Reads directly from your existing Android contacts (via DAVx5, Nextcloud, or any contacts sync) and layers relationship tracking on top: interaction logging, follow-up reminders, birthday alerts, social profile links, and per-contact notes. You can also log interactions with numbers not saved in contacts.
What's different
No new silo or cloud account required — it builds a CRM on top of contacts you already have instead of a separate database.
Pricing
Free.
Best for
Android users who want lightweight relationship tracking without creating a new account or syncing to a third-party cloud.
