I released this iPhone app few months ago - JustRemindIt - http://justremindit.com. It's an app to send voice call based reminders to your friends, clients and yourself. Just type the reminder message and date, and our service will call a desired person at a scheduled time.

Many businesses and individuals use this app on daily basis. The iPhone app already makes decent money, but I'm more excited about the upcoming Web application, which is specially targeted for small service and professional businesses. I'll be releasing this web app very soon.

This is my first side project, which solves a real problem, makes decent money, and growing slowly but steadily. You can reach me at aditya at justremindit dot com.
