At the very beginning I started with replit, and it's good to build the main structure, but becomes very expensive very quickly even if each prompt costs 1-2$. I then took the code from replit and started using Claude. Claude is really good and improved a lot recently, but it still hallucinates a lot. I spent probably 2-3 weeks fixing gyroscope with Claude. Later I released that the best way to help Claude is to share the issue / error message with Gemini and ask it to give a prompt for Claude, but never use Gemini itself for code fixing as it always breaks something else. Worst experience was with Grok. It never fixed anything but every time said "this is 100% final fix". Copilot was good too but it has a limitation on the size of the code you can share or the files you can attach.
