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

Link: https://ohyahapp.com

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

React Native/Expo + Firebase. On the App Store after months of dogfooding with the family

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 :)

Thanks! They actually liked the photo part. Right now just focusing to handle daily routine but could expand later depending on the feedback

Yeah, that's a valid concern. We use an older spare iPhone for this, which worked out well. iOS doesn't have a "Kids Corner" equivalent unfortunately - you'd need to use Screen Time restrictions to lock down the device (block apps/calls/etc) but still need to unlock the phone

Thanks! This was my wife's idea and I thought it's interesting but was skeptical at first. But after we started using it, it actually helped a lot! Much less whining/crying and a lot less stressful for my wife and I

So at least it works for my family, and just like you said, it's a huge win by itself :)

gantengx — Wed, 08 Oct 2025 08:15:49 +0000

Hi HN! I built Oh Yah! to help my sons (age 7 and 10) stick to daily routines without constant reminders. The core idea: minimal distractions during tasks by locking navigation when a timer is running, plus optional photo-based task completion for accountability

Built with React Native/Expo and Firebase. The trickiest part was designing the UX to be simple enough for kids with minimal distractions while giving parents enough control – ended up with a task-definition system that lets parents create weekly schedules with daily toggles instead of duplicating tasks across days

It's on the App Store now after a few months of dogfooding with my family. There's a 1-month free trial, then it's subscription-based. Would love feedback from other parents dealing with similar challenges

For the monospace font I still revert back to DejaVu Sans Mono/Menlo. Somehow other fonts just doesn't click and feels a bit off

Show HN: Chessterm – Rust-based terminal chess engine for chess notation

gantengx — Tue, 04 Feb 2025 13:34:50 +0000

Hi HN! I just built chessterm, a Rust-powered TUI chess engine to practice chess notation (PGN) for an upcoming chess competition. This was also a way for me to learn Rust more deeply, particularly bitboards for move generation and terminal UI development with ratatui

Unlike typical chess UIs that wrap around Stockfish, this is built completely from scratch, with: - PGN-only input (no AI, just human vs human) - Bitboard-based move generation (u64, precomputed attack masks) - Built with ratatui for a smooth terminal experience

Would love to hear your feedback!
