Apps for
the first
five seconds.

Native iOS & Android and React Native apps. We design around one question: what does a real person feel the first five seconds after opening it?

§ 01 — Surfaces

Three contexts, three postures.

A phone held in the hand at a café — native iOS finance app by Triune Softwares 01 / Finance
Finance · In transit

Pocketed by the elevator.

The finance user checks once, decides once, dismisses. We design one glance that answers four questions.

A phone resting in a pew — Stewards mobile app for parishes, built with React Native 02 / Stewards
Stewards · At rest

Placed on the pew.

An institutional companion app for Stewards, our parish SaaS. Silent by default. Legible in cathedral light. Designed to be ignored, then consulted.

ulted.

A phone beside a journal and coffee cup — editorial iOS app interface by Triune Softwares 03 / Journal
Journal · At morning

Beside the pen.

A ritual app, not a notification app. Opens to the page. Closes cleanly. Treats the screen like paper.

§ 02 — Principles

How we decide on mobile.

One hand, one thumb

Primary actions reachable from the lower right. Every screen passes the commute test.

Silent by default

No badge, no vibration, no banner unless earned. Attention is the scarcest resource we design around.

Animation as punctuation

Motion marks transitions and consequence — never decoration. 180ms or less, almost always.

Offline-first

Local-first data, optimistic writes, graceful sync. The subway is the real device.

Accessibility is the baseline

VoiceOver, TalkBack, Dynamic Type, contrast — considered at wireframe, not shipped as an audit.

Install day is day one

The first five seconds are our brief. We design the empty state as carefully as the full one.

§ FAQ — Frequently asked

Questions we hear often.

Common questions from product teams evaluating a mobile engagement with Triune. If yours is not here, email us and we will answer candidly.

Should I build native iOS and Android or React Native?

It depends on the product. If the app lives or dies on platform feel — gestures, animations, deep OS integration — we build native in SwiftUI and Jetpack Compose. If your team needs one codebase and your app is primarily content, forms, and data, React Native with Expo is a serious option and ships faster. We will recommend honestly in week one, not sell you whichever is more profitable for us.

How much does it cost to build a mobile app?

A focused native app on one platform runs CAD $60,000 to $120,000. A full two-platform build (iOS + Android) or a React Native app that ships to both runs CAD $90,000 to $200,000. Pricing is fixed-scope against a written brief. App Store and Google Play fees are separate and paid directly by you to Apple and Google.

How long does mobile app development take?

A production-quality mobile app on a single platform takes twelve to twenty weeks from kickoff to the App Store. Two-platform and React Native builds take sixteen to twenty-four weeks. We publish a weekly build you can install on your own device from week four, so the product is never a black box.

Do you handle App Store and Google Play submission?

Yes. We prepare screenshots, copy, privacy disclosures, and App Privacy labels, submit the build, and manage the review cycle on your behalf. You keep the developer accounts in your name so ownership is always yours, not ours.

Can the app work offline?

Yes. We design offline-first for every app where it matters — local-first storage with conflict-free sync when connectivity returns. It is harder to build but it is the only way a mobile app feels native on a spotty connection, which is most real-world use.

Do you publish for both iOS and Android?

Yes. We ship to both platforms in parallel for most engagements. If budget only allows one at launch we typically recommend iOS first in North America and Android second three to six months later, but we will walk you through the trade-offs against your actual audience.
