About

Founder, builder and tech enthusiast from the Netherlands. I run Dream Hosting, where I've been working with hosting, servers and web technology for years. I also love building my own products and turning ideas into simple, useful software. Currently building Loggr and Billr, with a strong interest in SaaS, automation, self-hosting and AI. Always experimenting, improving things and probably running a few too many side projects.

Billr - One-tap time tracking that turns into paid invoices

Billr is a time tracker and invoicing app for freelancers and small teams. Tap once to start the timer, tap again to stop, and your hours land on the right client and project by themselves. Turn tracked time into a branded invoice without retyping a line, then get paid by card or PayPal. It works fully offline. The timer keeps running and invoices keep saving with no signal, then sync across your devices the moment you are back online. Free to start: 3 invoices and 3 quotes a month, no card.

Loggr - See how everything you track connects.

Loggr is a flexible personal tracker for habits, mood, sleep, energy and more. Six field types let you track anything, from a 1-10 mood scale to blood pressure or a short journal note. Logging takes seconds, and Loggr automatically shows how the things you track connect, even from one day to the next. A smarter alternative to streak-only trackers. Private by design, EU-hosted and available in 24 languages. Free to start on iOS, Android and web.
