It’s the app which I have been using to stick to my resolutions. I believe the name stands for minna de challenge meaning challenge together in English. It works very simple, five peopl who share the same target gather and make a team, then team members post photos of what they did to achieve the target on their forum.
The concept of the app is “I can’t do it alone, but we can do it together”. We sometimes encourage each other and feel good pressure from other members’ posts.
Thanks to the app, now I can stick to my new year’s resolutions. Actually I gave up one of them until now, but it is not bad for me as I was the kind of person who gave up all the resolutions in three days after I decided.
