Remember those guys from Boston startup Achvr who sprinted all over the city to hit 72 local hotspots in 72 hours on Columbus Day weekend? They’re back with a new challenge, only this one is for you. It’s far less strenuous, and you can win cash.

To celebrate the launch of its goal-tracking app out of beta, Achvr will kick off the 52 in 52 Challenge on Feb. 1. As the name suggests, the idea is to hit one goal every week for a year. A weekly drawing will give somebody $100 to spend on accomplishing a goal.

The Achvr app is a handy way to set and, of course, achieve your goals — whether we’re talking about taking a trip to Australia or just trying that new restaurant around the corner. It helps you find cool things to do and connects you to people in your social networks who have the same ambitions.

For those of us with a competitive streak, it also enables side-by-side comparisons of our own accomplishments and our friends’.

A new feature now delivers discount offers, based on your to-do list. Hoping to take salsa lessons some day? When the local dance studio runs a promotion, you’ll know about it.

To get in on the $100 giveaways, download the app and opt in to the 52 in 52 contest. You can rack up bonus entries to improve your chance of winning by using the app and getting friends to use it, too.
