APPROACH

A portfolio built to keep growing.

Privacy as a product rule

Apps are designed around local control, transparent storage, and minimal data collection wherever the platform allows it.

Focused, not fixed

Each product starts with a clear workflow, while the portfolio can expand into new categories without changing the PuffiLab promise.

Native Apple app development

Apple platform features such as Health, iCloud, widgets, Live Activities, and Apple Watch support are used when they make the product better.
