WHAT IT DOES
Pick the platform. We'll build the app.
Four shapes most product teams need. Single-platform, both-platform, plus the surfaces (macOS, watch, CarPlay).
Multi-platform
- Shared backend
- Native UI per OS
- Synced state
- Shared auth
- Shared analytics
RECENT SHIPS
Three apps, three verticals. Each shipped inside the quoted window.
Anonymized by industry, scale, and platforms.
WHY IT HOLDS UP
Why your app feels right on day one, and why only native keeps it that way.
Four things that separate a real native app from a hybrid app dressed up in App Store packaging.
Apple Intelligence in Swift. Native apps reach it. Hybrid can't.
Three system-level surfaces that shipped in iOS 26 and macOS 26 (September 2025). Native apps reach them. Hybrid apps can't.
Foundation Models
Apple's on-device LLM, callable from Swift since iOS 26. Free inference, offline, privacy-preserving. Generation, summarization, classification, structured output via the @Generable macro.
App Intents
How Siri, Spotlight, Visual Intelligence, and Shortcuts find your app in 2026. Without proper App Intents, your app is invisible to the system AI layer. With them, your app gets surfaced inside the iOS intelligence flow.
Writing Tools
System-level Writing Tools (proofread, rewrite, summarize, transform) hook directly into every text field in your app via the standard APIs. Users get Apple Intelligence everywhere they type.
Not sure which of these surfaces you actually need? A Native App Scope maps it in 2 days.
HOW WE PARTNER
Half the features come from us. On purpose.
Most native app shops build exactly what you spec. We think with you. We have shipped 800+ native apps and we live inside the 2026 AI and OS stack, so we surface opportunities your team has not seen yet during scoping. On a recent regulated-healthcare build, half the shipped features came from our recommendations, not the original brief.

Features the original brief left on the table.
HOW IT DOESN'T SCREW UP
Five things keeping you up. Five built-in answers.
Every concern below has a mechanism behind it. Not a promise, a wire.
WHAT IF
“You're not an app shop.”
18 YEARS + 800+ APPS
Deep Mist's team has shipped 800+ native apps across 18 years inside mobile-first product orgs. Senior native engineer on keyboard, not an agency PM in front of an offshore squad.
WHAT IF
“Will we own the code and infra at the end?”
FULL IP TRANSFER ON FINAL PAYMENT
Source repository with full git history transfers on final payment. App Store Connect / Play Console accounts are yours from day one (or transferred to your team). Signing certs, provisioning profiles, build configs, infra docs, backend keys all delivered. No proprietary build pipeline, no in-house framework that holds you hostage.
WHAT IF
“Native means double the cost vs hybrid.”
SHARED BACKEND + PLATFORM TOOLING
The expensive layer (backend, auth, analytics, data model) is shared whether you ship one platform or three. Native only adds cost in the UI layer, where it pays off: gestures, animations, accessibility, OS integrations. The second platform is incremental, not a rebuild, because only that UI layer is platform-specific.
WHAT IF
“App Store rejections will delay us.”
PRE-REVIEW + GUIDELINE COVERAGE
Every build runs through the Apple / Google review-guideline checklist before submission. Privacy nutrition labels, content rating, IAP rules, sandboxing, permissions strings, and metadata are reviewed by a human against the current store policies. CarPlay entitlement (2 to 6 weeks of Apple review) is filed in week 1 so it's not on the critical path.
WHAT IF
“What happens after the launch payment clears?”
OPTIONAL RETAINER + 30-DAY WARRANTY
Every build comes with 30 days of bug-fix coverage at no charge after store listing. Optional retainer covers the iOS / Android annual release cycle, store policy changes, SDK version bumps, and crash triage. There is no lock-in: the code is yours, documented well enough for an internal team to pick up.
HOW WE'D BUILD YOURS
From Figma to App Store. In weeks, not quarters.
14 to 35 business days from first brief to a live store listing. Less than the typical premium native shop takes to send the first scope deck.
1
Scope
0 to 2 daysWe learn the product. Who uses it today, what platforms matter most, where native pays off vs hybrid, how the backend is shaped. We pick the tier with you and lock the surface list (iOS only, iOS + Android, plus watch / TV / CarPlay). This is the Native App Scope above when run as a paid pre-build engagement.
2
Design + prototype
3 to 7 daysWe design the core flows native-first. Figma + a working SwiftUI / Compose prototype of the highest-stakes flow inside week 1. You see the app feel on a real device before code lands on production paths.
3
Build + TestFlight
7 to 21 daysWe build the app end to end. Daily TestFlight / Internal Track drops. Your team plays the app on real devices every day. We fix what breaks. We harden what feels off.
4
Store submission + production
Day 0 onwardWe file the App Store / Play Store submission. We respond to reviewer feedback. The app goes live. Optional retainer covers OS-update cycles, store policy changes, and ongoing crash triage. We hand over the keys, you tell us when to come back.
What we need from you to start
- Designs, or a rough idea we shape into designs with you
- Your backend and API access, or a note that we build that too
- An Apple Developer and Google Play account, or we set them up alongside you
- Brand assets and the real content the app ships with
- One decision-maker who can approve scope in 2 business days

AFTER LAUNCH
Launch is a checkpoint, not the finish line.
- Post-launch support is included with every build. We fix what we shipped. Every build comes with 30 days of bug-fix coverage at no charge after store listing.
- When iOS or Android ships a breaking change, there is a maintenance track for it. No surprise rebuilds.
- Source repository with full git history transfers on final payment. App Store Connect and Play Console accounts are yours from day one (or transferred to your team).
- Optional ongoing retainer if you want us on call. No lock-in.
Who this is not for.
- If you have not decided what the app should do, start with a Native App Scope.
- If your budget is below our entry tier, native may be the wrong tool, and we will say so.
- If you want an offshore body shop, we are not a fit.
WHAT WE DON'T DO
Six things we leave to the rest of the market. On purpose.
No web view in a frame.
No offshore subs. Senior native engineer on keyboard.
No T&M billing. Fixed fee, fixed scope, fixed timeline.
No 6-week scope deck. Scope locks in 2 business days.
No post-launch ghosting. 30 days of bug-fix coverage, optional retainer.
No proprietary build pipeline. Standard Xcode and Gradle, handed to your store accounts and signing keys.
Tell us what the app should do. We'll ship it to the store.
Walk us through what the app should do, which platforms you need first, and what success at launch looks like. We'll reply with a real number and a real timeline. Typically 2 business days.
Brief if you know what to build. Native App Scope if you want us to figure it out with you.
