Not working

I used this app last year on my iPhone 5c and it was amazing. I downloaded it to my iphone 6 this year and it is stuck on day 1. Everyday it still flashes on day 1 and doesnt show that I completed it or the days after and everyday it shows me the same app thats supposed to be that days "present". I gave it three stars because I enjoyed it last year but this year it should only get one because it is totally glitching. I even deleted it and reloaded it. Although I do like the catchy song they play everyday. It makes me feel happy and excited and I really like it.
