Apps for
the first
five seconds.
Cross-platform iOS and Android apps, built with React Native and Expo. We design around one question: what does a real person feel the first five seconds after opening it?
Three contexts, three postures.
01 / Finance
Pocketed by the elevator.
The finance user checks once, decides once, dismisses. We design one glance that answers four questions.
02 / Stewards
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.
03 / Journal
Beside the pen.
A ritual app, not a notification app. Opens to the page. Closes cleanly. Treats the screen like paper.
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.

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.
Do you build native iOS and Android, or React Native?
We focus on cross-platform mobile development with React Native and Expo. One codebase ships to both iOS and Android, which is faster to build, cheaper to maintain, and the right call for almost every product we have been briefed on. If your app genuinely lives or dies on deep native OS integration — intensive graphics, very specific hardware control — we will tell you honestly in week one and point you to a native specialist rather than over-promise.
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.
