Count down (or count up!) with these big retro-digits. You can keep track of multiple events that are in the future or are milestones in the past. You can also keep a running counter of how long since you ... quit smoking, been married, been alive, been clean and sober, etc. T-Minus Events will even pop up reminders for you when your event gets near, like an anniversary or birthday. And you can set an event to automatically renew on a yearly, monthly, or weekly cycle. This is the ideal App to help you track every important event.
