A bit frustrating and waste of time and money. There’s other appt that allow you to sent to your email and text. ### 1/5 — Horrible *2025-03-13, version 1.1.3* Cannot add more than 1 photo for my notes. The notes are not detailed. I have emailed them 10 times for a refund but they do not email back. Such a waste of $90 and I didn’t even know they were gonna charge a whole year worth of fee at once and now I’m broke !!! Wouldn’t even give this app 1 star if I could I would give 0. ### 2/5 — Buggy, paid for pdf feature ( useless) *2025-02-24, version 1.1.2* - I had paid for the pdf feature to scan notes and generate a test, though it only generated a test if the instructions and how much each question was worth ### 1/5 — Invalid Email address *2025-02-11, version 1.1.2* The email address in the terms and conditions for refund support does not work and is invalid. I wanted to send an email for a refund but the email provided was invalid and does not exist at all. I felt like I was royally ripped off. ### 1/5 — Very buggy *2025-01-10, version 1.0.9* Not really usable with all the bugs ### 1/5 — Other Feynman apps are better than this *2024-12-25, version 1.0.8* Don’t like it ### 1/5 — Useless *2024-12-13, version 1.0.8* Not worth the money ### 2/5 — Pay *2024-12-09, version 1.0.8* Only good if you can pay for it otherwise you can even speak to it ### 1/5 — Not working *2024-12-06, version 1.0.8* Results are not good at all ### 1/5 — Got charged *2024-11-29, version 1.0.6* I got charged $ for the 3-day free trial. Clearly got scammed and no one is answering. I am reporting. Don't get the app! ### 1/5 — Bad *2024-11-03* Like everything is with money bruh like even start talking is with money and the app is for this **Developer response:** We're sorry to hear that!

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. ### 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 ### 1/5 — Its a Scam *2025-04-15, version 1.1.4* Literally they give you two free notes to upload, than you need to buy premium to do anything. Just delete it and commit your time to studying, the app when creating my flashcards had the wrong information as well. ## Most praised reviews (10 highest-rated) ### 5/5 — Feynman *2025-07-14, version 1.1.5* This app helps a lot to study the technique is too good and gives very good results ### 5/5 — This app is it *2025-04-19, version 1.1.5* Literally goated for chem ### 5/5 — review *2025-02-19, version 1.1.2* grate, really functional ### 5/5 — Finally *2025-02-03* 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 **Developer response:** Thank you for your review! ### 5/5 — Request Refund *2025-01-09, version 1.0.8* Can I get a refund, it accidentally purchased.
