### 1/5 — Paid Subscription

*2026-06-23, version 2.2.1*

The app shows Free plan I paid the full price it shows in the subscription so I cannot determine what I cannot access so I have been battling this thing pretty bad

### 1/5 — Still causing me problems

*2026-06-04, version 2.2.1*

I initially had problems with the app crashing repeatedly. Now that has been fixed and I have purchased a membership, I was very excited to start using the app and boosting my learning. However everytime I try to use the feynman AI, it says “unable to transcribe your answer, please try again”. I have been trying for 2 whole days on my ipad and my iphone. Both times I have received the same results. My exam is in 36 days and i am desperate for this issue to be fixed, otherwise I would like my money back. I have faced endless inconvenience with this app. I have emailed twice about it aswell and received no response

### 1/5 — App crashes

*2026-05-06, version 2.2.0*

I downloaded this app so I can study. I downloaded on both my phone and ipad and both times the app keeps crashing every single time I open the app. I would really like to utilise it as Feynam is critical to my studying but if the app isnt even working, how can I?

### 1/5 — This app sucks

*2026-04-11, version 2.1.0*

I can’t use the YouTube to create any note. YouTube creation is broken.

### 4/5 — It's ok but we need to pay for less

*2026-01-07, version 2.1.0*

I like the app overall but what i don't like is that we have to pay after a certain amount of notes for like forever and not just for that day.

### 1/5 — I thought it was gd at first..

*2025-10-23, version 2.1.0*

So i was scrolling through pintrest, happily, until this woman came up on a pin and was talking abt how gd this app is. After explaining how to use it she said it was completely FREE. Just wut app i was looking for, i thought. So i downloaded the app and made my first notes. I was really happy until i tried making a new set of notes. Thats when i realised I had to pay. Paying is not really helpful u c, i am a 14 year old girl who doesnt  make money. How in the world am i meant to pay to use the utilities on this app if i dont earn money? Anyways, i started to read the reviews and a lot of them are about how u need to pay. If i were u, i would start to take action instead of saying ‘we r always looking to improve our app’ or wutever. If this app doenst improve, then im going to be forced to move back to quizlet, and i dont want to do that.

### 1/5 — I regret spending money in this app

*2025-10-22, version 2.1.0*

I paid for one month and I never got what I paid for. It doesn’t help on anything. After recording my class it still say process note until today, I wasted money and can’t recommend it to anyone.

### 1/5 — Finally

*2025-09-16, version 2.0.1*

I don’t usually write reviews honestly but this app did really help me so much in chemistry I don’t think I could have done done it without this apps help they way they explain it to you is so nice the notes the Memo and the mindmaps too and they test you on knowledge the you get to talk to an ai that helps you too I don’t think I could have asked for better app and even when I’m struggling in English or math class I sometimes ask this app and it helps me and explains it to me in a way I can understand it i just wanted to say thank this app really did help me with my school
Update: they changed the whole app now the ai that help you understand hard topics they toke it out honestly that was the one thing that helped me understand the hard topics it broke it down into a way anyone can understand now idk man it’s just now the same I don’t have the app anymore if you could bring the ai chat back that would be amazing I don’t mind paying for it but it’s just the main thing is gone and it’s just not the same. I hope you can bring back the ai chat.thank u

### 1/5 — Maldito

*2025-08-28, version 2.0.1*

Como me pides que te pague cien Lucas por esto!, estupido

### 1/5 — No funciona

*2025-08-19, version 1.1.5*

No especifica los límites, y al intentar repetidamente con audios y documentos me da error
