### 5/5 — топ!

*2026-02-06, version 2.1.0*

Но почему нельзя контролировать что ты хочешь там выбирать?

### 1/5 — 請問有沒有操作說明？

*2023-08-30, version 2.1.0*

小孩遊玩時有錄音功能，但是不知道如何觸發錄音玩法.

有比較詳盡的使用方式嗎？ 

為何會有天九牌的設計？

### 5/5 — Amazing! However…

*2023-05-09*

I love the Tinybop States of Matter app! It's an amazing educational tool that makes learning about the different states of matter easy and fun. The graphics are visually stunning, and the interactive elements are engaging and informative. 

However, I would love to see Tinybop create an app that covers more topics in chemistry, such as chemical reactions, elements, compounds, and molecules. I think it would be an excellent addition to their educational lineup, and I'm sure their team would do a fantastic job creating it. Overall, I highly recommend the Tinybop States of Matter app, and I look forward to seeing more chemistry-related apps from them in the future.

**Developer response:** We're considering this!

### 4/5 — Awesome

*2023-01-30*

My six year old has been wanting to experiment with temps and changes of matter, she loves this…but we can’t figure out the sound? It’s likely user error. How can we get assistance?

**Developer response:** Hi. Let's try a few things. There are lots of ways to turn off sound in iOS. We try to respect system settings, but many apps don't which can be confusing. 1. Make sure your iPad is not on hardware mute (on most ipads and phones it's a sliding button on the side that shows a bit of orange when it's in the mute position). Many apps don't respect this setting. 2. Make sure the volume is up. (use the hardware volume buttons on the side of the iPad/iPhone). 3. Make sure the sound isn't muted via the app. Touch the key on the side of the app, then the gear, then you should see a speaker). Make sure it's on. 4. Try the suggestions in this video: https://www.youtube.com/watch?v=TnG4r_EyiUQ Several other folks with this issue said, that the video solved their problem, but they didn't tell us exactly which step! 5. Do a full reboot. This sounds like voodoo, but it works for many! Good luck! Let us know how it goes.

### 5/5 — Makes an dry subject fun
