ShotZen - Clean up your expired & duplicate screenshots with AI

Your screenshots know a lot about you: OTP codes, receipts, passwords, boarding passes. ShotZen cleans them privately, fully on-device. It finds expired screenshots, duplicates, receipts, travel docs, and more automatically. No uploads, no servers, no accounts. Free to scan and preview. Pro unlocks bulk deletion, full categories, and faster processing.

DueSight – Private Subscription Tracker - Track subscriptions, avoid surprises, and stay in control.

I built DueSight to solve a simple problem: I kept losing track of subscriptions. Streaming, AI tools, apps — small charges add up quickly. So I made something simple: • See all subscriptions in one place • Get reminders before renewals • Understand your monthly spending • No tracking. No ads. Your data stays on device DueSight is designed to be fast, minimal, and private. If you’ve ever been surprised by a charge — this is for you.

JingNote - The voice note app built for bilingual thinkers

JingNote is built for how bilingual people actually think and speak. Tap to record, get accurate transcription in both languages, manage your notes cleanly. No friction, no broken sentences mid-thought. Built by a solo developer who got tired of re-typing everything after every voice memo.
