Filament is a self-funded mobile app studio. We dream up our own ideas and craft them start to finish under one roof — beautiful, simple apps that help people.
One senior team, one roof. Every idea is designed, built, and shipped by the same hands — start to finish.
Native-grade iOS & Android products that feel fast, fluid, and considered.
Simple, beautiful interfaces that get out of the way and just feel right.
Every pixel and every line is ours — designed and engineered by the same hands, start to finish.
We're self-funded — we build the products we believe in, then share them with the world.
We pick an idea we believe in — something simple that genuinely helps people.
One team, one app, full focus. High intensity, heads down, no distractions.
We launch it polished and whole — beautiful and simple, the way it should be.
Then straight into the next idea, carrying everything we learned with us.
Peridot is out now on the App Store. Here's what else we're shaping right now.

Just a period tracker, done beautifully. Pay once — no subscription, no nags — and your data stays on your phone.

A shopping filter for natural fibers. Set your number, point it at any store, and everything below your bar simply never shows up.

Origami you can fold along with. Sixteen traditional models in living 3D — every crease on screen is a real crease on the sheet in your hands.
We take on a tiny handful of outside ideas each year — and only as real partners, for a meaningful stake. If yours is exceptional, tell us about it.
