Silent Manager Whitelist -lite is a free Android app developed by ServeMe in the Social & Communication category. It is a simple yet effective app that helps you manage your silent status for calls and SMSs. With Silent Manager, you can create a whitelist of contacts, and if anyone in the white-list contacts you, your phone will act as if it were in normal mode. This app is particularly useful if you need to stay alerted to specific contacts while your phone is set to silent mode.

Silent Manager Whitelist -lite allows you to select a contact that contains multiple phone numbers, and integrates fully with your contact application. It also supports Android 2.3 or up, reminds you to check your whitelist, and has long-press help on any item. Additionally, it is compatible with third-party programs like schedulers.

However, it does have some limitations. You can only add up to five contacts to your whitelist, and the app contains advertisements. It also doesn't have sleep time settings. Overall, Silent Manager Whitelist -lite is a great app if you need to stay alerted to specific contacts while keeping your phone in silent mode.
