Next title is being bench-tested. Watch this slot — the studio doesn’t ship empty promises, just finished builds.
What’s in the works03_signature
Engineering detail is the product, not the footnote.
Real specs, not sales pitch
Version code, target SDK, file size, permissions — every app page lays out the raw numbers. No guesswork, no hiding behind "lightweight" claims.
Focused by design
No feature bloat, no bundling five apps into one. installr opens packages, CalciHub crunches numbers — each tool masters its own lane.
Privacy is the baseline
No forced accounts, no silent telemetry. installr runs fully offline; CalciHub lets you sign in only if you want to sync. Your data stays yours.
Found a bug? Want a feature?
The studio answers every message. Tell us what’s broken or what you wish an app did — it lands directly in the dev inbox, not a ticket graveyard.
