### 2/5 — Couldn’t even open the first box

*2026-07-07*

As I loaded the app excitedly it upset me that I couldn’t open the initial box to get started no matter what I try I can’t get it to work uninstalling and reinstalling, anything. I’m sure it’s a great app but just be aware that this issue may happen.

**Developer response:** We’re really sorry — that’s a terrible first experience, especially when you were excited to try mug. 😔

The first box should open smoothly, so we’re looking into what could cause this. If you’re willing, please email us at mail@trymug.com with your device model and iOS version so we can investigate and help you get started.

Thank you for taking the time to report it.

### 3/5 — Lag

*2026-08-19*

It looks like a good app but every time I try to open my mug it keeps on crashing through out the animation it’s kinda annoying

**Developer response:** We’re really sorry — opening your mug should never crash, especially during the first reward animation. Thanks for reporting it. We’re actively looking into this animation issue and working on making the opening flow smoother and more reliable. If you’re willing, please email us at mail@trymug.com with your device model and iOS version so we can investigate faster. Thanks again for trying mug. 😔

### 5/5 — Amazing!

*2026-06-29*

Really expanded my vocabulary and makes it easier to write short stories and stories alike without googling better terms for things. I love the widgets and TOTALLY recommend! 🥰

**Developer response:** Thank you for the lovely review! We’re so glad mug is helping you find better words for your stories. That means a lot — and we’ll keep improving the app to make the daily word habit even better! 😍
