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.
Not happy with new format
Annetterudge
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?
Developer Response
This update is an all-new app for iOS 15. But the important part is the same. We are very sorry for the frustration caused by the many changes. Unfortunately, there are no plans to separate the old app. We will definitely consider updating the balloons. Thank you for using this app for a long time.
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 :/.
Great app just needs reminders
sdbland87
Perfect to track what you want just wish it would send you a daily reminder
• Between midnight and your Day Cutoff Time, the home and habit screens show the day your checks count for, with a short notice.
• The habit screen shows the date you're checking for (today or yesterday).
• Unchecking yesterday now asks first when it would shorten your streak.
• If premium products can't load, you can close the screen or try again.
• You can cancel when deleting a habit from Statistics.
Wishing you success on your 66-day journey!
