Notevision Sight Reading

Last month I deleted 20,000 lines of dead code, built an XP system, open-sourced it, and started rebuilding my entire lesson curriculum. The real shift isn't speed — it's staying in product mode instead of implementation mode. ryannewso.me/blog/solo-dev-…

Dev changes this week in Notevision: 🔔 Smart Review Prompts — no more nagging on launch. Now triggers after level ups, streak milestones, and 3-star rounds 🎵 Guided Lessons V2 started — 10 new MusicXML-based lessons with a real pedagogical sequence (landmark notes → intervals) 🐛 Fixed key signature restart not refreshing + iCloud sync crash at launch 📦 Open-sourced PracticeXP — our XP engine is now a standalone Swift Package (56 tests, MIT) The app will be updated soon!

Been making a lot of progress recently. Took a library from my app and made it open source: ryannewso.me/blog/practicex…

Notevision has been on the App Store for 10+ years with 1M+ downloads. Still building. Still shipping. If you're learning piano, try it — it's free 👇 apps.apple.com/app/notevision…

📊 The week by the numbers: • 16 PRs merged • 49 files changed • 1,641 lines added • 284 lines removed • 0 teammates

This week I shipped 16 code changes to my piano sight-reading app. Solo dev. No team. Here's what went in 🧵

🛡️ Crash hardening pass — 28 fixes across 17 files. Replaced force unwraps, unsafe casts, and added unit tests. The kind of work nobody sees but everyone benefits from.

Been working on two new upgrades to the app! Syncing of history and settings between devices and a leveling/xp system. Starting beta testing now!

Music is awesome, so is skiing @breckenridgemtn

Slow tempo is not “taking it easy.” Slow tempo is precision training.

Happy New Year! I hope everyone reaches their musical goals for 2026!

I think everyone needs a creative outlet. Music is a great option

@Hyeosnsi1 I agree. It’s been on my list for a while and I hope to get to it at some point. I’ve been thinking about how to implement it with my current system in a way that is fun to practice. Thanks!

@sightreadingapp hello, a great feature would be rythm detection in the sight reading and also time signature options, additionally a helpful feature for singers like myself is to add the option of a treble clef 8vb and giving the option to play a starting note before you begin.

@atharva_sarage Hello, that is good feedback. I’ll consider it for the future. Thanks!

@sightreadingapp I would like to have the progress dashboards to be per lesson type (Treble, Bass, Grand Staff). For example for me I am relatively very much better at Treble Clef but need improvement on the base clef, so the treble clef exercises are messing up the dashboards.

New version released and rolling out now! 8.5 brings a new key signature practice which will have you easily recognizing key signature by their staff accidentals.

I hope people are enjoying the key signature reference if they downloaded the latest version. I am now working on a key signature practice where a staff and accidentals are shown and the user selects the correct key signature name. Will have more to share soon!

New feature released in version 8.4. Key signature reference in the "Chords +" section. Let me know if you have any feedback!
