Bondwidth Contact management app for Android description
Bondwidth is an all-in-one phone, contacts, and relationship app that works entirely on your device. No accounts, no servers, no tracking — and it quietly helps you stay close to the people who matter.
Friendship is small attentions, often. Set a check-in cadence for each person and Bondwidth gently flags whos getting too quiet, so you can reach out before silence becomes a habit. Birthdays and anniversaries are remembered for you, and the calls you make are counted automatically.
Private by design
- No internet permission at all — the app cannot reach the network, and its build pipeline fails if that ever changes.
- No accounts, no servers, no cloud. Everything stays in the apps private storage on your device.
- No analytics, no ads, no third-party trackers.
- Optional encrypted backups (AES-256-GCM) that only you can open.
- Optional biometric app lock and a hide from screenshots mode.
Phone
- Default dialer with its own in-call screen, Picture-in-Picture, and per-contact ringtones.
- T9 smart dial, speed dial, and dual-SIM call routing.
- Block numbers, missed-call notifications, call history and search.
- Colour-coded call directions, with optional WhatsApp / Signal shortcuts.
Contacts
- Browse, create, edit and delete contacts, with group filtering.
- Typed phone numbers, emails, postal address, website, organisation, notes and birthday.
- Find and merge duplicates; import and export vCard files.
Bonds
- Per-person check-in cadence with gentle overdue nudges.
- Birthday and anniversary reminders, with a Mark as wished action.
- An interaction timeline and an at-a-glance relationship dashboard.
