LetPiano v1.0.20260624 (build 3) was archived in Xcode and uploaded to the App Store — both the iOS and macOS builds passed validation. Three falling-note play modes, a Theory Park with 5 advanced mini-games, and 19 public-domain songs — all offline, zero ads, no data collected. After months of solo development, its first step into Apple review.

Six days into review, an email arrived from App Store Connect: "There's an issue with your LetPiano - Piano for Kids (iOS) submission." — the iOS build was flagged with an issue that requires attention. It's LetPiano's first rejection, and a milestone almost every indie developer meets on the way to launch; the specifics live in App Store Connect's Resolution Center, and the next step is to fix and resubmit.

Three days after launch, App Store Connect Analytics gathered its first meaningful data. No ads, no paid promotion — purely organic App Store discovery brought LetPiano its first players. The numbers are small, but for a solo developer's first shipped app, they're the first proof that real people are downloading it.

The first update, 69 days after launch. 1.1 and 1.2 were written but never submitted — the store page was still running 1.0 copy, so this Description and What's New had to cover everything since 1.0. Archived 1.3.20260905 (6) at 8:38 PM on Sep 6, created the Draft Submission at 9:06 PM — with only the app version in the basket. Foreshadowing.

Build 6 passed review on Sep 7 — but the three tip IAPs were left outside the basket. Apple's rule: an app's first IAP must be submitted in the same review basket as an app version, and an already-approved version can't take passengers. So 1.3.20260907 (7) (zero code changes) went out the same night at 11:55 PM as one basket of four items (version + 3 IAPs); Ready for Distribution arrived at 9:04 the next morning — about 9 hours, no questions asked. The short-lived 1.3.20260905 on the store simply hid its tip section (no products found), so users saw nothing broken.

• Approved: 1.3.20260907 (7)　·　iPhone + iPad　·　4 items (version + 3 IAPs)
• Submitted: Sep 7, 11:55 PM　·　Approved: Sep 8, 9:04 AM　·　Status: ✅ Live
