I'm Khai Do, an independent developer. This domain hosts what I work on: the pages a shipped app needs.
A subscription and bill tracker for iPhone and iPad. It keeps renewals, trials and recurring bills in one list, reminds you before a charge, can add renewals to your calendar, and helps you decide what's worth keeping. It needs no account, and your records stay on your device and your own iCloud.
Available now on the App Store
Everything here is built and maintained by one person, which is the reason it stays deliberately small. Each project gets a page that explains it, plus the support, terms and privacy pages a shipped app needs.
It reaches me directly. It's a mailbox that gets read, not a ticket queue. Expect a reply within a few days, in English or Vietnamese.
