Simple family contacts

Add important people to the OneStart home screen so they are easier to find and call. Contact details and preferences are stored locally on the device.

WhatsApp video calling

For a configured family contact, OneStart can optionally check for a matching WhatsApp video-call entry in the phone’s contacts and open that entry when the user taps the WhatsApp button.

This feature is always initiated by the user. OneStart does not read chats, collect screen content, upload contacts, answer calls, or place calls in the background. WhatsApp must be installed, and the contact must already be available through the phone’s contacts provider.

Volume Lock

Volume Lock can restore media, ringtone, notification, and call volume to a level selected by the user. It is optional and can be turned off at any time.

Privacy and control

OneStart explains why a permission is needed before requesting it. Core launcher settings, family contacts, and preferences stay on the device.

VIP features are available during a 7-day trial and can then be unlocked with an optional one-time purchase. Basic launcher features remain available after the trial. There is no subscription or automatic renewal.

OneStart is designed for seniors, older adults, family-supported phones, and anyone looking for a simple launcher with big buttons, large controls, easy calls, and a clearer Android home screen.

OneStart is an independent app and is not affiliated with or endorsed by WhatsApp.
