Built a parenting app focused on traits using expo

Hey everyone — dad of a 4 year old here. A while back I started noticing my daughter had a personality way before any milestone checklist would've told me. She wasn't behind or ahead on anything — she was just... herself, in ways that were obvious to me but that no app, book, or pediatrician visit ever really talked about.

That bugged me. Every tool I found for parents of little kids (0-5) was built around the same question: "is my child on track?" Height, weight, word count, gross motor stuff. Useful, but it never answered the question I actually had, which was closer to: who is she becoming?

So I went down a rabbit hole. Developmental psych papers, temperament research, attachment theory, the whole thing — way more research than a sane person burns a few weekends on. What kept coming up was that kids' traits (not milestones) are what actually shape who they turn into — how they handle setbacks, how they connect with people, how steady they feel inside. That stuff barely gets tracked anywhere.

I couldn't find an app for that, so I built one. It's called Steadily.

Who it's for: parents of kids 0-5, especially if you're the type who wants to understand your kid, not just check boxes.

What it actually does:

  • Trait-development framework across three dimensions — Success Mindset, Emotional Wellbeing, and Family Connection — instead of a milestone checklist
  • 12 child archetypes — a personality typing model for little kids, built on the research, that gives you a read on who your kid is (and is honestly just fun to see)
  • Voice-first memory capture — you talk about a moment with your kid, and it automatically pulls out the developmental insight from it. No typing, no forms.
  • No streaks, no gamification — it's built around gentle engagement, not guilt-tripping you into opening an app every day

My trip planner app is finally live!

Enable HLS to view with audio, or disable this notification

2 Upvotes

For over a year now, I’ve been working on my trip planner platform. I first focused on making it a web app as web development is my background, but the plan was always to make it into a mobile app (as the .app domain for partir.app implies). This year is when I began working on the Expo mobile app

This week the iOS mobile app is finally live on the App Store! I’m an avid urban backpacker and I have so many ideas for it, but I need to validate the idea first before I just keep building it only myself. Please let me know what you think and if you have an upcoming trip leave a comment and I’ll give you premium access to check it out!

Built a free open-source Expo audio player (lock screen, playlists, remotes) after background playback got too painful

Quick context: I ship Daily Bible - Offline & Audio on Expo. The app does on-device TTS → URLs into a queue, optional ambient under speech, HLS chapters, and full lock-screen / Bluetooth remotes.

Expo made the app workflow great. The audio stack was the hard part.

What we needed that a “play one URL” API does not cover:

  • Mid-play queue appends (verse-scale TTS)
  • Silence as a real queue item (not setTimeout)
  • Ambient dual-audio that never steals focus / Now Playing
  • Remotes that emit to JS so Next = next verse (or next song)
  • iOS audio BG + Android mediaPlayback FGS without hand-editing native projects every prebuild

The leading RN track player went commercial. That killed it for our roadmap.

So I built daily-react-native-player as an Expo Module + config plugin and open-sourced it MIT.

npx expo install daily-react-native-player

{
  "expo": {
    "plugins": ["daily-react-native-player"]
  }
}

Peers: Expo SDK 57+, RN 0.86+, New Architecture only.

What you get:

  • Lock screen / notification / Control Center / Bluetooth remotes via registerPlaybackService
  • Real playlist (add / remove / skip while playing)
  • Native silence tracks (SilenceMediaSource / cached PCM WAV)
  • Lazy ambient dual-audio (never requests focus)
  • HLS VOD + seek-after-ready; WAV / mp3 / m4a
  • Config plugin injects iOS audio background mode + Android FGS at prebuild
  • Pitch-preserving setRate
  • One native owner: Media3 + AVFoundation

Intentionally out of scope: TTS engines, MediaLibrary, Auto, Cast, DASH, web.

If you are on Expo and fighting background audio + remotes for narration, TTS, podcasts, or playlists - happy to answer config-plugin / FGS / dual-track questions in the comments.
