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 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.
