I built a family of pay-once iOS apps — no subscriptions, no ads, on-device

I'm an indie developer, and I made one rule for everything I ship: one-time purchase, no subscriptions, no ads, and your data stays on your device. No monthly fees, no accounts, no tracking.

Here's the lineup so far — all for iPhone.

🗂️ Productivity & documents

  • ScanTo Pro — scan to a searchable PDF with OCR, lock docs with Face ID, works offline.
  • CV Desk — instant ATS résumé score + recruiter-ready templates.
  • G+Money — convert currencies and log every expense in one tap, offline, no bank linking.
  • HoursTag — see what a purchase really costs in hours of your life.
  • LockHour Pro — block the apps that steal your focus, one tap.
  • Mochi — cute, cozy checklists with a satisfying tap to complete.

📷 Photo & privacy

  • Unblurry — AI super-resolution sharpens & upscales photos, entirely on-device.
  • PicClear — find duplicate photos & huge videos, free up storage fast.
  • Snapport — take a compliant passport/ID photo at home in 30 seconds.
  • PhotoCream — 100+ real film looks, grain & light leaks.

🌙 Health & calm

  • Cyca — private period & cycle tracking, on-device.
  • Sereno — a sound machine for sleep & focus: mixable white/brown noise, offline.

🧒 Kids & learning

Why pay-once?

Subscription fatigue is real. For most everyday tasks, a one-time purchase does the job without an open-ended cost — and keeping everything on-device means there's no account to leak and nothing to cancel. That's the whole idea.
