One outcome per build
Each build tracks one outcome you choose, such as installs, in-app purchase revenue, or day-30 retention.
Your developer reports that number monthly.
Proof in every iOS app we submit
Every Dcrayon iOS build rests on six pillars: App Store metrics you can verify, Swift you can audit, and plain numbers your finance team can read.
One outcome, whole build
Scoped and tracked Every iOS build is measured against one number you name on the scoping call, whether that is paid installs, crash-free sessions, or in-app purchases. The engineer on your account reports it each month, not a wall of charts.
Senior engineer writes the Swift
Kickoff to release The senior engineer who scopes your iPhone app writes the Swift and uploads the App Store build. You are not funding someone's first project in Xcode.
Current Swift, since 2016
Dcrayon AI toolkit Every build ships in current Swift and SwiftUI, with async/await and SwiftData where they fit, so the app runs well on the latest iPhone and iPad.
Month-to-month after cycle one
No yearly tie-in Work runs month to month once the first cycle closes. We keep the account by shipping updates that lift ratings and retention, not by locking you in.
Backend and Android in reach
Room to extend Your iOS app connects to a backend API, an Android build, or a web admin when you need it. Nearby mobile and software work stays with the same team.
Reports finance can read
Weekly call, monthly summary A weekly call with your developer covers the sprint and TestFlight feedback. A monthly summary maps App Store metrics to the goal, in plain language.
HOW DCRAYON IOS APP DEVELOPMENT WORKS
Inside a Dcrayon iOS app 90-day build cycle
A quick look at a Dcrayon iPhone app cycle, from the week-one Score readout through TestFlight betas to a live App Store build.
What is iOS App Development?
iOS app development means building native iPhone and iPad software in Swift and SwiftUI. The three cards below explain what it covers, how our engineering differs, and how we measure each release.
Step 1: What iOS app development covers
Definition A native iOS app runs directly on iPhone and iPad, written in Swift and SwiftUI rather than wrapped web pages. We build it as a maintained product: versioned in Xcode, shipped through App Store Connect, and pointed at one goal you set.
Step 2: Why a Dcrayon iPhone app is different
Difference Since 2016 we have shipped apps that hold up on real devices, weak networks, and strict App Store review. We write testable Swift, watch memory and jank in Instruments, and stage each release through TestFlight before it reaches the store.
Step 3: How we measure your app
Measurement We open with an audit of your current build or spec, then hold a short call each week. A monthly summary your finance team can read tracks the goal, and either side can close out cleanly after the first cycle.
Technical signals we build into every iOS app
Default work on every Dcrayon iOS app build
Each item below ties to something your app depends on to earn and keep users: launch speed, crash-free rate, App Store rating, and day-30 retention. Built and reviewed by the iOS engineer on your account.
Dcrayon AI toolkit applied
Our in-house toolkit flags Swift smells and likely crashes early.
A senior engineer reviews every pull request before it reaches a TestFlight build.
Speed and memory tuning
We profile with Instruments for leaks, allocations, and frame drops, so the app stays smooth on older iPhones.
XCTest coverage is included, never a paid extra.
Dcrayon Score baseline
A 150-point check runs at the start, across crash-free rate, launch time, App Store guideline fit, and code quality.
It sets the baseline we build from.
Weekly call plus monthly readout
A weekly call on the sprint and TestFlight feedback, plus a monthly summary linking App Store Connect metrics to the outcome.
Reporting terms sit in the agreement.
Exit open each cycle
Work runs month to month once the first cycle ends.
Either side can close the agreement at a cycle boundary. We keep the account by shipping releases that hold up.
Three Dcrayon tools behind every iOS app build
The Score, the Sequence, and the build toolkit: a health check, a written cycle plan, and the kit we run on every iPhone and iPad project.
Dcrayon Score (Mobile and Software axis)
A 150-point health check. The mobile axis covers crash rate, launch speed, App Store fit, and code quality inside every project. Free on the proposal call.
Dcrayon Growth Formula (iOS app sequencing)
A written cycle plan that ties each sprint back to one outcome. Shaped over years of shipping iPhone and iPad apps through App Store review.
Dcrayon AI (builder toolkit)
Our in-house toolkit runs across projects to flag Swift issues early, suggest fixes, and keep the app fast and the code readable.

Question & Answer
Frequently asked questions
Real questions app owners ask Dcrayon before signing on.
You do not wait until launch to see the app. We share running TestFlight builds through the project, so you test real screens on your own iPhone at each milestone and judge the work as it takes shape.
Many agencies bill for hours logged. As an iOS app development company since 2016, we ship native Swift and SwiftUI, keep the crash-free rate high, pass App Store review cleanly, and tie each release to the number you care about.
iOS app retainers usually run Rs 1.8L to Rs 5L per month for a single-region build. Larger or enterprise apps go above Rs 7L.
No. Work runs month to month once the first cycle closes, and either side can exit at a cycle boundary.
iOS app development is one of several Dcrayon Mobile and Software services. Many clients start with an iPhone app, then add an Android or backend build alongside it. See the full Mobile and Software overview at /services/mobile-software.
