- Terrible
- Keeps crashing
- It's so manipulative. It told me I needed a credit to scan a math problem, and I could get a credit by watching an ad. After 1 watched one  ad, it said I needed to watch 3. Fine. I watched 3. Then 6. Then 7. No word of a lie. Deleting. Don't waste your time. Also the ads are ads for gaming apps. Not helpful for students. 🙄

**Requested features**

- Wish was free
- Wish they had a clearer step by step option if you need more explanation
