Chiamate Perse is a free Android application developed by Suxsem under the Utilities & Tools category. The app provides a notification service for every missed call when the phone is busy or unreachable. It also allows users to check their missed call history within the app and block unwanted numbers by customizing their blacklist. The app is small in size and does not consume much battery. It is easy to use and can be activated on multiple phone numbers simultaneously.

The app provides a "Who called" service without having to pay your telephone provider. For the first 14 days, you can try the app for free, and then it costs only $0.99 per year. The app does not include any advertisements to provide the best possible user experience. The app's developers have decided to ask for a small annual contribution to cover the costs of infrastructure and app development.

The app also ensures maximum security from any cyber attack. The app does not store any call history, and no personal information is stored in the system. Your telephone number is used to generate a unique, non-invertible code associated with the device, which is then used to send notifications to the right user. If you have any questions or need support, you can contact the developers at
