Corine
Corine is an AI personal assistant you can talk or type to for everyday help — answering questions, managing tasks, and pulling in context from your contacts, calendar, or location when it's useful. Requests are processed through a cloud AI service to generate responses; your conversation history stays stored locally on your device, and there's no account to set up.
Where Am I
Where Am I
Listed on Google Play as "Where Am I: Residency Days"
Counts how many days you've spent in each country, so you always know where you stand against tax-residency thresholds like the 183-day rule. Detection runs automatically in the background, on a schedule you set — every trip and log stays on your device unless you choose to export it.
I'm Christophe — I work in tech and write code for fun on my spare time. This site lists the apps I publish and the legal pages that go with them, kept as simple as I can make them.
