Can’t edit habits and no support

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 :/.

Not happy with new format

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?

Love the concept but needs improvement

I love this app to keep track of new habits but I wish you could go back and change and mark the habits done on each day because after it turns 12:00am on the clock it won’t let you mark your completed habits from the day even if you completed them. This is what bugs me so bad about this, because it’s messing up the progress on the tracking even though I completed all the habits.
