And I pay for the subscription. And if I’m paying the subscription but not able to use the app I’m just wasting money. It’s very disappointing but has the potential to be a very good and helpful app. ### 2/5 — So *2026-01-22, version 4.0.4* Was wrong most of the time ### 3/5 — Платно *2025-10-15, version 4.0.2* Все просто прелесть! Только после 1 раза сразу подписка ### 4/5 — Price *2025-10-15, version 4.0.2* 6,99 per week is crazy ### 5/5 — Vanessa *2025-10-03, version 4.0.2* Awesome ### 5/5 — Best Homework Helping Assistant *2025-09-23, version 3.9.6* Works Very Well, Explains how answer was found, Perfect! ### 5/5 — Was great *2025-09-19, version 3.9.6* Was a great app until everytime I opened it it would just freeze the app is unusable now ### 5/5 — This is a good app *2025-09-17, version 3.9.6* This helped me so gooooppppppoood ### 1/5 — SCAMMING KIDS/REPORTING *2025-09-17, version 3.9.6* I cannot find anywhere to contact customer service. My daughter subscribed to this app for a free trial without my consent, on her tablet. I was charged yesterday. When I emailed the email address connected to the charge, no response. When I searched the app and click on App Support there’s a page not found error. I need a refund, how can I reach customer care service? ## Most critical reviews (10 lowest-rated) ### 1/5 — Not Lifetime *2026-07-07, version 4.0.6* I made the lifetime purchase in 2024. I went to use the app today and it’s telling me that I need to make a purchase again. ### 1/5 — Not happy *2026-07-06, version 4.0.6* I paid a one time fee for a hole year to be able to use this app and it’s asking me to pay again for it? Not cool. So not happy 😕 ### 1/5 — Dysfunctional of sharing bottom *2026-07-03, version 4.0.6* With the best , I tired to reach many times customer service by sending email, nobody answer me back. I have annual subscription. I m not sure the problem how is disappeared but I n not able share my data because the share bottom is not working! I reinstalled the app and installed but the problem is still there ! ### 1/5 — Malandragem *2026-06-21* Sem pagar o app acerta todas as respostas, mas quando você paga ele erra todas as questões ### 1/5 — Dysfunctional share future *2026-04-26, version 4.0.6* I have this problem and after three times sending emails , I can not share my data with my one drive to save ! ### 1/5 — Disappointed customer *2026-04-08, version 4.0.6* I would like a refund for the past several months as the app has not worked nor opened for me and I and still being charged!!! ### 1/5 — Lifetime subscription is a scam *2026-02-24, version 4.0.4* I bought a lifetime subscription with NerdAI on my old Android phone, and got a new iPhone. tried signing in my old account, with no success. Turns out customer service sees lifetime subscription as Device-specific. Meaning, if you want to save money and buy the lifetime purchase and you lose/break your phone or ,worse yet, it gets stolen, that’s on you. Not fair at all! ### 1/5 — Terrible *2026-02-07, version 4.0.4* You took $6.99 again in Jan. 2026 when I had canceled a year ago, and yet you are still able to take $ from me, how and why? You owe me, and should refund me back all the money you have been taking from me every month since I canceled a year ago with you! ### 1/5 — Stolen Money *2025-12-23, version 4.0.3* Apple stole my money from this app. ### 1/5 — Dios que mala es para gente con dinero *2025-10-27, version 4.0.2* Hey soy pobre no tengo plata, cómo quieres que pague, simplemente soy un estudiante que quiero mejorar, y me dices que hay que pagar para usarla. ## Most praised reviews (10 highest-rated) ### 5/5 — Best app *2026-06-04, version 4.0.6* All the math AI apps i used, charged me for money to take pictures and get explanations for my problems without having to pay!!
