Lives the idea of the app, but if you miss a day or accidentally enter an incorrect item, there is no way to change it. I tried to connect support and got no reply - this is a no-go for me :/.

I miss the balloons and woke up to all my information for power habits missing with a new update. It’s frustrating to have to start over and then realize I need to import my old data and now it’s out of order with the transfer and feels like a totally different app 😨 I was doing so well for 639 days except when I was on an airplane and my data didn’t save in airplane mode. I wish there was an edit button so I can fix the missing days I noted on paper. Any chance of having the new version be a separate application?
