Apps for a brighter tomorrow
Ideas into extraordinary.
We design and build exceptional iOS apps that make life better. Small, native and private by design — each one does a single job, beautifully. And we build the same way for others.
Apps
Seven apps, seven jobs.
Household rhythms, the working day, recurring money, recovery, warranties, the bills a couple shares and the training block. Different problems, one way of building: a screen you understand at a glance, your data on your device, Spanish and English from day one.
Cycle Timers
Recurring household timers you read at a glance — from the Home Screen widget, without opening the app.

Drip
See exactly where your money drips: every subscription, bill and membership shown as what it really costs a year.

Anchor
Daily support for eating-disorder recovery: routines that hold you and tools for the hard moment — alongside professional treatment, never instead of it.

Philosophy
Beautiful. Useful. Human. Possible.
Four words we hold every screen against. If a feature fails one of them, it doesn't ship — however clever it is.
Beautiful
Design with an opinion: one dominant colour, weight before size, motion that means something. The kind of care you notice without being told.
Useful
Every app answers one real question people ask every day, and answers it on the first screen. No dashboards for their own sake.
Human
No accounts, no analytics, no advertising, no dark patterns. Your data lives on your iPhone and in your own iCloud — we never see it. Copy written for people, in two languages.
Possible
Native all the way: SwiftUI, widgets, Live Activities, Siri and Apple Health when they earn their place. Small teams can build things that feel first-party.
Work with us
The same craft, for your project.
We take on a small number of client projects a year — the ones where we can bring the same standard we hold our own apps to. If you need something built well, talk to us.
iOS apps
Native Swift and SwiftUI, from the first sketch to the App Store: product thinking, design, code, review and the release itself. Widgets, Live Activities, Siri and iCloud when they earn their place.
Websites and web apps
Fast, accessible sites and web applications that are pleasant to use and simple to keep — from a landing page like this one to a full product.
Custom development
Tooling, integrations and the automation that removes a job nobody should be doing by hand. Scoped, delivered, documented.
How it works
Tell us about your projectScope
A written brief with what ships, what it costs and when. No surprises halfway.
One lead
One of us owns your project end to end and is the person you talk to.
Delivery
Working software at every milestone, source code and documentation yours from day one.
Studio
Two developers, one bar.
Seize Apps is Izotz and Sendoa, two co-founders from the Basque Country. Every app is the two of us: the same standard of craft, the same care, from the first sketch to the release.

We ship our own apps and we build for clients, and we stay small enough that the person who wrote the code is the one reading your email.
