You are absolutely right—a bug with the new Handbook images caused the app to crash on launch for some iPhone models. The good news: I have already identified and fixed this issue. Version 2.0.13 is currently 'In Review' with Apple and should be available for you to download very soon (likely within 24 hours). Please update as soon as you see it, and the app will open perfectly. Thank you for your patience! — Roman ### 5/5 — A lot of problems are missing solutions after the update *2026-01-22* I just downloaded this app and it looks very promising. One immediate bug I found is that when I search for a specific problem. The problem description seems to come from a different problem and I had to swipe left or right to find the actual problem of that number. Update: the issue above has been fixed, however most medium/hard problems don’t have solutions anymore. **Developer response:** Hi Cosnno! Thanks for the 'Almost Perfect' review—I want to make it totally perfect for you. The bug where search results loaded the wrong problem content has been fixed in the update I just released (Version 2.0.11). It was a caching issue on my end. Please give it a try now! If the app runs smoothly for you after the update, I'd love to earn that 5th star. Happy coding! — Roman ### 5/5 — Nice for studying on the go *2026-01-22* Edit: The developer quickly updated the issue in response to my original review. Real professional and on top of things. Much easier to study on the go when everything is showing as normal! Original: The descriptions on LOTS of problems don't actually match the real problem on leetcode. **Developer response:** Hey Jdswagdaddy, thank you for spotting this. You were absolutely right—our recent multi-language update caused a sync issue that mismatched some descriptions (like Triangle showing Two Sum). I just pushed Version 2.0.11 specifically to fix this data integrity bug. Please update the app, and it should be 100% accurate now. If it works for you, I'd appreciate it if you could update your rating! Thanks for helping me improve the app. — Roman ### 1/5 — Lots of incorrect descriptions *2026-01-12* The descriptions on LOTS of problems don't actually match the real problem on leetcode. For example, the description for 'Triangle' is actually the description that matches two sum. See this on many problems. **Developer response:** Hey Jdswagdaddy, thank you for spotting this. You were absolutely right—our recent multi-language update caused a sync issue that mismatched some descriptions (like Triangle showing Two Sum).
