Problem!!

I had glow nurture on my iPad and just downloaded it on my android phone. But I have a problem. When I look at my phone, the amount of time that I logged for how long I slept appears as minutes. Like, if I had logged 7 hrs, it shows on my phone like I slept for only 7 min! So I changed it to be correct on my phone, but now it says that I slept 400 hours on my iPad! I'm confused!! Help!
