Notifya is a free Android app developed by Supersense under the Utilities & Tools category. It is the world’s first app that has the ability to reliably detect the opening of a door by using your device’s microphone to monitor the pressure wave that opening a door causes, and can do so even with background noise such as music or TV.

With Notifya, you can keep a 24-hour ear out for your entrance and get alerts every time a door is opened or shut. It doesn’t require any special setup or positioning, and it works on most smartphone models. The app logs alerts with time, date, and signal strength, and Notifya Pro users can sync multiple devices and receive alerts on remote devices. It also offers smart home integration with Home Assistant.

Notifya is simple and easy to use, making it ideal for anyone who wants to know exactly when or how many times their door is opened. Notifya can help you ensure that children aren’t opening doors or you don't miss a delivery.

In terms of privacy, Notifya analyses audio in real-time and no personal information is ever gathered. No audio is permanently recorded or stored anywhere.

If you’d like to remove ads, add other devices, and unlock more features, you can upgrade to Notifya Pro within the app with a simple, one-off purchase.
