About the studio

A short list of apps. A long view.

Euler Tech Co., Limited is a private company limited by shares, incorporated in the Hong Kong Special Administrative Region under the Companies Ordinance (Cap. 622). The studio designs and ships mobile and web apps, and intends to keep doing so for a long time.

Our approach

Software made for use, not metrics.

Each product we ship is something we believe people will keep installed — not something designed to maximise session time, notifications, or engagement scores. A review in the App Store is a real message from a real stranger, and that is the signal we care about.

The studio is self‑funded. That means the apps answer to the people who use them, not to investors with a growth curve to hit.

What we believe

Positions kept returning to.

Make it small

A product with one clear job is almost always better than one trying to do several. Features get cut until something breaks.

Respect attention

Notifications off by default. Streaks, badges, and artificial urgency belong in casino design, not in apps worth making.

Price honestly

Free things say free. Paid things say what they cost, in the currency of the person looking. No trials that auto‑convert silently.

Ads are guests

Where an app is ad‑supported, ads sit in clearly marked spaces. They never appear mid‑tap and can always be removed with a one‑time purchase.

Privacy by default

The apps collect what is needed to work, and nothing else. What is collected is documented in plain English.

Stay in reach

Every app has a human support address. Most messages get a reply within two working days.
