Keeping track of birthdays is what a calendar is for. Keeping track of random numbers and numerical coincidences is what Versaries is for. The 99-cent iPhone app keeps track of the years, days and even seconds of your life with a steampunk feel. Add in when you started dating your significant other, and you’ll be reminded of more than just your regular anniversary; recently Versaries pointed out I’d been dating my girlfriend for 80 million seconds. Time seems to fly faster when you’re not counting by years. www.versariesapp.com.
