What I love most is that it doesn’t just give answers — it provides helpful hints when she gets something wrong, guiding her step by step so she can actually understand her mistakes. My daughter can independently check her homework without cheating, and she’s genuinely learning in the process instead of just correcting answers. It’s helped build her confidence and responsibility, and it’s been a huge help for me as a parent. Highly recommend this app for middle school math! ### 5/5 — Great for kids and parents! *2026-01-26* Love this app! It makes me and my kids to really think and learn instead of giving the straightforward answer! It works for paper-based and screen-based homework and over all topics ! ### 5/5 — So good!! *2025-12-12* This is so good. We use it with my 3rd grader especially for writing, math and Spanish work. ### 5/5 — Lifesaver for busy parents *2025-12-01* Works especially well for parents on the go!I’m a very busy mom juggling life and career. With this app I’m able to quickly check homework and help my fourth grader on her homework instead of needing to go through every question or piece of writing. ## Frequently asked questions about Co ### What subjects can Checkmate check?
