Do you regularly forget your iPhone is in silent mode only to find several missed calls and messages? If so, this simple utility might help.

The only way of knowing your iPhone is in silent mode is to notice the little slider switch is down on the side, as there is no persistent indicator on the screen. Unless you count missed calls as a persistent indicator, that is.

How to use:
When you switch your iPhone into silent mode, just touch the Silent app icon and exit Silent straight away by pressing the Home button (or have Silent exit by itself to save you a keypress using 'One Touch', described below). The icon badge is set to '222' (a bit like 'zzz') to remind you the iPhone is being silent. Likewise, when switching out of silent mode, run the Silent app again and the badge is removed. For best results place the app icon on your home page or even in the bottom section so you can see the status from any springboard page.

Silent also features 'Push Reminders'. When the app recognises it is in silent mode, it schedules a reminder to be sent to you via a push notification after a specified (via Settings) amount of time. When that time arrives, if you have not yet switched out of silent mode (and touched the app) you will receive a push notification reminding you that your iPhone may still be in silent mode. If you have configured vibrate in your iPhone's Sounds -> Silent settings, then it will also vibrate.

In the Silent settings (via the iPhone's Settings panel) you can configure the app to quit automatically so that you don't even need to press the home button. Additionally, set the 'quit delay' to 0 seconds to prevent the app from even displaying. The result: you have a super fast 'One Touch' action to set the reminder!

Remember - You do need to run the app each time you slide the silent switch on your iPhone. There is currently no way to avoid this. If you use the 'One Touch' feature, then sliding the switch and touching the app becomes second nature and almost painless.

When you download the app you receive the 'Basic' version to get the opportunity to try out all the features straight away. After a period you will then have the option to purchase the 'Premium' version to continue using all the features. Alternatively you can continue to use the 'Basic' version at no cost but the 'One Touch' and 'Push Reminders' are no longer available. If you find the app useful then the modest cost of the app should pay for itself when you reduce the number of calls and messages you might miss.

Silent is only of use for iPhone. The iPod Touch has no silent mode. Remember also, that for the app to recognise the silent setting no headphones can be attached while you run the app. If headphones are connected, the app will ask you to briefly unplug them while it checks the silent status.
