Great app, but UI needs an overhaul

I’ve been waiting a long time for a great accountability app like this. This app gets the job done with motivating me to accomplish various goals. My only complaint is the user interface and lack of features preventing this app from being perfect.

My suggestions
1) Each challenge needs its own page (similar to a Facebook event) where the creator can write a description of the challenge along with rules/requirements instead of having to explain via the chat
2) chat needs a feature to mute all but who you follow or the creator. I don’t like being bothered by numerous notifications from people having their own private conversation in the chat.
3) ability to search for challenges/ categories of challenges. Currently I can touch the “join a challenge” but it’s blank. Not sure if it’s just a glitch with my app, but it would be nice to search for specific challenges

Otherwise I love the app and am looking forward to improvements in the future!

Oh hey abs ,

Check ins won’t upload, getting charged

Another update: please please please STOP forcing us to Sign In with Apple!!! That stupid pop up come up every. Single. Time. I interact with something. It even comes up one on top of each other and then I have to dismiss it various times!!!

Update — they resolved my issue. I still won’t give 5 stars because they do have this uploading problem. But happy they were able to help.

This app was soo good for a while. And now so many check ins have trouble uploading. There’s A LOT of glitches. Because one of them wouldn’t upload in my attempts to delete it to record another the check ins never updated and remained as if I completed the check ins for the week. Only to find out once the new week started that it marked 6 missed check ins which is impossible because the challenge was only 5 check ins a week and all 5 checking were there when you went back to look at them. I’m not being charged for all those missed check ins for something completely out of my control. I’m just waiting till I’m im done with these challenges and I don’t plan to continue the app until they fix these issues. Not when all that money is on the line. I’m so disappointed.

habits are a blessing ,

5 stars if it wasn't for bugs

Update: Thank you for your response! I just downloaded the new version as of yesterday and there are a lot of big changes that have seemed to resolve most of the past bugs from the past. Thanks!!

Having used this app on and off since December, I feel obligated to update my review when necessary. The app is tremendously awesome if you make the most of it. But one thing that gets in the way are the updates. The updates seem to add more bugs/ problems than not. At the time of my last review I made mention that the new updates added a lot of social networking features, but some of the core issues with the app, like checking in without errors, seeing the list of recent, active challenges in your feed, and more, have yet to be implemented in a smooth fashion. I think now March 2021, there have been a lot of improvements but also a lot of bugs and I’m hoping that a new big update will come about to correct this.
