The home screen
that thinks for Grandma.
Juno replaces the cluttered Android menu with large, clear buttons. Set up by the family in ten minutes – operated completely on its own, every day.
The accessible home screen with large, clear buttons and an SOS emergency call function.
A smartphone isn't built for 80-year-old eyes.
Too many icons
Dozens of app icons on a single screen overwhelm instead of help. Which one was WhatsApp again?
Buttons too small
Shaky hands and tiny font are a poor match. One slip – and the wrong app opens.
One click too many
An accidental press of the back button, and the familiar interface is suddenly gone.
Six features that truly matter in daily life
Each feature solves a specific problem that families have actually reported to us.
Buttons for shaky hands
Long press instead of short tap can be enabled for each button individually. No shaking, no accidental clicks.
Three contrast modes
Light, Dark, or maximum contrast with yellow text on black. The perfect view for any level of vision.
Large battery indicator
Below 20%, an unmissable prompt appears: "Please connect charger" - with a large graphic.
Volume protection
If the ringtone is accidentally muted, Juno automatically restores it to the configured minimum.
Tactile feedback
Every button press triggers a short vibration. Confident feedback that the click went through.
Stepless text zoom
Normal, Large, or Huge: The font size of all buttons and indicators can be adjusted with a slider.
One button for emergencies. No ifs or buts.
In an emergency, every second counts! Any unnecessary click is too much. The emergency button on the home screen requires only a single tap.
- 1A tap on the red button starts a loud 5-second countdown that can be canceled.
- 2After that, Juno automatically dials the saved emergency number, without further confirmation.
- 3At the same time, relatives receive an SMS with the location as a Google Maps link.
Set up by you. Operated completely on its own.
