## Kinnu Reviews in United States

### ****- "Amazing but latest update broke something"
This app is a fantastic learning tool that has definitely helped me choose it over things like til too. However the latest update has made it so it crashes on startup. Once that’s fixed I would change my score to 5 star’s personally.
-- XenoMars, 2024-12-31

### ***** "Excellent way to learn"
Awesome way to learn new things and recall what we have learned before!!!
-- ectalan52, 2024-12-28

### ***** "Amazing free app"
This is by far one of the best apps I have used. Lots of good information and all for free! Fantastic recall tests are integrated as well. Very impressed by this.
-- Jackpot1776, 2024-12-27

### ***** "Awesome app"
I love the format of being quizzed as i read. helps retain so much.
-- gogito3000, 2024-12-25

### ****- "Really like but could improve"
I really like this idea and enjoy learning topics in a smaller degree. I think the design and flow of lessons goes well too. The review at the end is also very helpful even if it does seem like I review the same things multiple times. 

There are a few things it can improve though. One main thing is the glitch that sometimes keeps you from even opening the app. Additionally, it was mentioned before, but it would be nice to have sources attached to the lessons as well. These improvements could make the app much more enjoyable.
-- Jm 222, 2024-12-24

### ***** "Exceptional"
Vitamin to the brain
-- Bihazerd, 2024-12-21

### ***-- "Great app, but now I can’t use it"
So for a couple weeks the app was absolutely spectacular, so many subjects, so much information, and such a beautiful system
 However, now, when using the app, it crashes, instantly, upon opening, I physically cannot use it all of the sudden, please help!
-- The emperor of tea, 2024-12-20

### ***** "Kinnu bite sized learning packs a punch"
I am impressed with the variety and wealth of information that the Kinnu app possesses. I used the app daily.
-- Buggasz, 2024-12-19

### ****- "one issue"
first off this has been a great source of strengthening my brain, even better than how school does it personally

however the only issue with this app is that you cant play music or other media in the background while interacting with the app due to the sound effects, my only request to the devs is to add sound settings and this would easily be a 5-star rating
-- nickher0000, 2024-12-19

### ***** "Good app"
It's a good app.
-- Lee6394, 2024-12-17
