https://chessnotate.app
It's a simple PGN app to help capturing chess notation from score sheet and fix the mistakes
Often my son and I made mistakes (mixing up b and B, or wrong rank, missing some moves) writing the notations and existing PGN parser simply stop at the first error and discard the rest. ChessNotate highlights the error while maintaining the original moves so you can see if your fix is actually fixes the remaining of the moves (or not)
Used it in the recent chess tournament and it's been really helpful

I built a routine management app for my kids (7 and 10) called "Oh Yah!" after their constant "Oh yah! I forgot" responses about homework

Interesting challenge was designing for minimal distractions while keeping setup simple for parents. Timer-locked navigation so kids can see what's next but can't start other tasks or switch profiles. Also refactored from schedule-centric (nightmare to maintain) to task-definitions as first-class citizens, which made creating schedules way easier

Thanks for this! Really appreciate it that it has no ads. Curious though, is the sound all generated on the fly or is it static audio file?

Thanks for this. Our child psychologist recommended structured routines, and paper-based scheduling just didn't work for us hence the app

I did consider that early on, but decided against it for now. Adding social features would be a privacy nightmare (especially with kids involved) and would significantly complicate both the UX and codebase

Fair points, and I appreciate the candid feedback. The demo tasks were chosen to showcase different task types (timed, photo-proof, etc) rather than being prescriptive about what kids should do. But I can see how it reads as "tiger parent starter pack"
For context: my older son genuinely enjoys chess and piano, and this structured schedule approach was recommended by their child psychologist. We tried paper-based scheduling but it didn't stick, so my wife asked me to build an app to help
Your point about useful adult skills is well taken. The hope is they internalise the habit of planning and following through, so eventually they can set their own schedules. We'll see how it goes

Ah we're pretty similar in that regard. Officially their screen time is 30min on weekdays (excluding the app usage and chess.com) so the app basically digitise that whiteboard + timer concept
Photo proof actually was my wife's idea. She wanted to verify the task quality when she wasn't at home - similar to your audit capability
I guess the 12year old battles will be coming for me next.. Not exactly looking forward to the puberty haha

Glad that works for you! We tried paper-based routines but they didn't stick for us. The timer helps them realize tasks take less time than they think, and the photo proof solves disputes about task quality when sometimes their "done" meant rushed with minimal effort :D

Thanks! Glad it resonates. The app is designed specifically for kids with a simplified UX and parent mode, so it might feel too basic for adults. However, the core concepts (ordered tasks, focus timer, photo completion) could work. Worth trying the trial to see if it fits :)

In this case, navigation means in-app navigation. When a task timer is running, kids can't switch to other tasks, go back to the main screen, or change profiles. They have to complete the current task first
The goal is to keep them focused on one thing at a time without the temptation to jump around :)
