Filament App Studios
Boutique mobile app studio · Launched 2026

We build apps
worth keeping.

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.

Crafted entirely under one roof
What we do

Everything an app needs,
made under one roof.

One senior team, one roof. Every idea is designed, built, and shipped by the same hands — start to finish.

Mobile apps

Native-grade iOS & Android products that feel fast, fluid, and considered.

Design that disappears

Simple, beautiful interfaces that get out of the way and just feel right.

Made under one roof

Every pixel and every line is ours — designed and engineered by the same hands, start to finish.

Our own ideas

We're self-funded — we build the products we believe in, then share them with the world.

How we work

Heads down,
one app at a time.

01

Choose

We pick an idea we believe in — something simple that genuinely helps people.

02

Sprint

One team, one app, full focus. High intensity, heads down, no distractions.

03

Ship

We launch it polished and whole — beautiful and simple, the way it should be.

04

Onward

Then straight into the next idea, carrying everything we learned with us.

In the works

Currently in the workshop.

Peridot is out now on the App Store. Here's what else we're shaping right now.

Peridot app home screen — next period countdown, cycle phase, and calendar

Peridot

Out now

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

Orikata app home screen — a paper swan on a red sun above the collection of origami models

Orikata

In beta · 2026

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.

By application only

Have an idea
worth building?

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.
