What we ship

One partner from idea to App Store & Play

Strategy, design, engineering, and release—so you’re not stitching agencies together when the launch date is immovable.

  • Android

    Ship faster on Google Play: Kotlin, Jetpack Compose, Material 3, and performance budgets your PM can read in a dashboard.

  • iOS

    App Store–ready SwiftUI and UIKit: polished UX, TestFlight feedback loops, and listings written to convert browsers into downloads.

  • Hybrid

    Reach both stores from one codebase when speed matters—React Native and native bridges where users feel the difference.

  • AI apps

    Ship assistants, vision, and smart flows where they reduce friction—on-device or cloud, always grounded in trust and clarity.

How it works

A process built for dates you can’t move

Fixed milestones, visible builds, and quality gates you can see—so stakeholders stay aligned and scope doesn’t quietly balloon.

  1. 1
    Discovery

    We lock scope, success metrics, and risks up front—so your first invoice matches what you thought you were buying.

  2. 2
    Design

    UX, UI, and motion defined before engineering churn—fewer surprises, faster approvals, clearer handoff to build.

  3. 3
    Build

    Weekly builds you can install, instrumented QA, and native polish at every size—velocity without cutting corners.

  4. 4
    Launch

    Store copy, screenshots, review cycles, and rollout plans handled—so submission day is a checklist, not a crisis.

  5. 5
    Scale

    Roadmaps, experiments, and performance budgets after v1—so growth doesn’t break what shipped.

Why Vivara App Studio

Fewer vendors. Faster path to revenue.

You get senior mobile execution with product judgment baked in—so your first release earns reviews and repeat opens, not emergency hotfixes.

  • Craft users feel in the first session

    Gestures, latency, and accessibility tuned for reviews and retention—not “good enough for MVP.”

  • Embedded like your own mobile team

    Slack/Linear-level responsiveness with production discipline—roadmap, risks, and ship dates you can plan around.

  • AI only where it earns trust

    Automation that saves clicks and explains itself—never a black box bolted on for a pitch deck.

  • Handoff you can run without us

    CI, monitoring, and release runbooks included—your engineers inherit a product, not a mystery repo.

Proof

Outcomes you can measure in the store

Velocity without cutting corners—teams come to us when downloads, ratings, and crash-free sessions have to move, not just slide decks.

  • Eleven weeks from kickoff to Play launch—crash-free sessions beat our old app on day one. Vivara App Studio treated our deadline like theirs.

    Jordan Lee

    VP Product, Series B fintech

  • NPS jumped after the hybrid rebuild. Users said it finally felt native—and the motion details showed up in store reviews.

    Samira Okonkwo

    Founder, wellness startup

  • They sell outcomes, not hours. Every sprint had something shippable; we always knew what “done” looked like next.
