About InstaDial: One-Tap Call Widget
Put the people you call most on your home screen as photo buttons. Tap one and InstaDial starts a WhatsApp voice or video call straight away. No opening WhatsApp, no hunting for the chat, no extra taps.
Think of it as a call shortcut you can see and press, right on your home screen.
One tap. The call starts.
• Contact widget (1x1): a round photo button for one person. Tap it and the WhatsApp call begins. Choose voice or video when you add it.
• Stretch it wider (2x1 and up) for separate voice and video buttons. Stretch it to 2x2 for a large photo with both buttons.
• Favourites widget (4x2 to start, resizable): your whole speed dial in one grid on the home screen, up to 12 people.
• App-icon shortcut: a photo icon the size of an app icon, if you prefer that to a widget.
• Quick calls from the InstaDial icon: press and hold it to call your first four favourites.
Set up in seconds
1. Install InstaDial and allow contacts access. Allow the Phone permission when asked: WhatsApp only starts calls for apps that have it.
2. Open the three-dot menu next to any contact and choose Add to home screen.
3. Confirm when your phone asks to place it.
4. Tap the new button on your home screen. The WhatsApp call starts.
You can also touch and hold your home screen, tap Widgets, find InstaDial and drag out One-tap call.
Made for parents and grandparents
Set it up once on their phone. After that, a call is one tap on a familiar face.
• Big photo buttons that are easy to see and press.
• Optional large tiles inside the app.
• Optional confirm-before-calling step, so an accidental tap never starts a call.
Also inside
• Favourites: big photo tiles you can drag to reorder.
• Search: smart search across names and numbers, forgiving of small typos. Swipe right on a contact for a voice call, left for a video call.
• Recents: calls you started from InstaDial, ready to call back in one tap.
Private by design
No internet permission. No ads. No tracking. Your contacts never leave your phone.
• InstaDial reads your contacts only on your device, to show who you can call.
• Your favourites, widgets and settings stay on your device.
Calls go straight through WhatsApp or WhatsApp Business, whichever your contact uses. Regular phone calls open your dialer when you need them.
InstaDial needs WhatsApp or WhatsApp Business installed, with the contact saved in your phone's address book.
