It is very easy to miss the initial sound of an incoming message or a phone call especially if the smartphone was in another room at this moment, in a leather wallet or in your jacket when you're in a car or at the street. If you don't want to check the display constantly to ensure that you haven't missed an important phone call or a message you might be waiting for then you need to try Best Reminder from Smartphoneware. It provides repeating alarms, visual notification and/or device vibrating to draw your attention to received but unnoticed messages and missed calls. This version is optimized for S60 5th Edition devices, including the 5800 XpressMusic and the N97.
