CallFlow: Forwarding Scheduler

Stop turning call forwarding on and off manually.

CallFlow automatically manages call forwarding around your schedule — and much more. Set the days and times, choose where your calls should go, add optional smart rules, and let CallFlow handle the rest.

Perfect for work phones, on-call rotations, after-hours forwarding, professionals and Dual SIM users.

AUTOMATIC CALL FORWARDING

Create schedules that automatically enable and disable call forwarding at the times you choose. Set it once and CallFlow takes care of the rest.

MULTIPLE AUTOMATIONS

CallFlow 2 lets you create unlimited forwarding profiles — each with its own schedule, destination number, and priority. Duplicate profiles, enable or disable them independently, and resolve overlaps with clear priority rules.

SMART TRIGGERS (OPTIONAL)

Go beyond the clock. For each automation you can optionally add:

• Wi‑Fi rules — forward when connected (or not connected) to a specific network
• Calendar rules — react to events in your calendar (title, busy/free)
• Location rules — forward when you enter or leave a place you define (geofencing, not continuous GPS tracking)

ON-CALL ROTATION

Manage on-call shifts with rotation lists. CallFlow assigns the effective destination automatically based on the date — ideal for teams sharing coverage.

RELIABLE & TRANSPARENT

• Forwarding event history with masked numbers
• Automatic retry when a carrier command fails
• Failure notifications with a retry action
• Recovery after reboot, timezone changes, and date updates
• Global pause for all automations without deleting your setup

HOME SCREEN WIDGET & QUICK ACTIONS

Control forwarding from your home screen. The redesigned widget shows status, active profile, masked destination, and next action — with Pause, Resume, and Off buttons. App shortcuts let you enable, disable, or pause forwarding in one tap.

BEAUTIFUL, MODERN INTERFACE

Material 3 design with Dashboard, Automations, History, and Settings. Light and dark themes. First-run onboarding with ready-made templates: Work Hours, After Hours, Weekend, On Call, and Vacation. Available in 7 languages.

PERFECT FOR WORK & ON-CALL

Use CallFlow to:

• Forward work calls after office hours
• Route calls during on-call shifts
• Automatically switch forwarding on and off

DUAL SIM SUPPORT

Using two SIM cards? CallFlow lets you manage forwarding for the appropriate SIM, making it ideal for phones with separate personal and work numbers.

PRIVATE BY DESIGN

Your schedules, profiles, and numbers stay on your device.

• No account required
• No cloud service
• No tracking
• No data sent to developers
• Optional features (location, calendar) only run when you enable them

NO SUBSCRIPTION

CallFlow is a one-time purchase. No recurring subscription and no advertising.

HOW IT WORKS

CallFlow uses your mobile network's standard call-forwarding commands (USSD/MMI) to activate or deactivate forwarding. Call forwarding itself is handled by your mobile carrier, just like when you configure it manually from your phone.

IMPORTANT COMPATIBILITY INFORMATION

Call forwarding commands and supported features vary by carrier, country and device. Your mobile operator may charge for forwarded calls according to your mobile plan. Location-based rules require location permission (including background access on Android 10+ for geofencing when the app is closed). We recommend verifying that call forwarding is supported by your carrier before relying on CallFlow for critical call routing.

SIMPLE. AUTOMATIC. PRIVATE.

Set your forwarding rules once and let CallFlow handle the routine.
