Get a project estimateBuilt the way Apple platforms expect
iPhone users notice when an app ignores platform conventions: swipe-back that fails, text that ignores Dynamic Type, a keyboard covering the input field. We design to Apple's Human Interface Guidelines, then fit your brand within them.
The App Store brings its own rules. Digital content and subscriptions used in the app generally need in-app purchase, while physical goods and real-world services can use gateways such as Razorpay. Apps need accurate privacy labels, a privacy manifest for certain APIs and SDKs, and in-app account deletion where accounts exist. We settle these in the first sprint.
iOS apps and capabilities we build
Premium consumer apps
Shopping, travel and lifestyle apps with polished motion, haptics and full Dynamic Type support.
Subscription and content apps
StoreKit 2 subscriptions and trials, server-side entitlement checks and restore purchases.
Health and wellness apps
Consultation and tracking flows, reading HealthKit data only with the user's explicit permission.
Widgets and Live Activities
Order status, delivery ETAs and booking reminders on the lock screen and home screen.
Business apps for teams
Apps for sales teams and managers with single sign-on, distributed privately via Apple Business Manager.
iPad and Apple Watch companions
iPad layouts for catalogues and counters, and watchOS companions for reminders and quick actions.
Reasons to go native on iOS
Platform-first feel
Navigation, gestures, accessibility and system fonts behave exactly as iPhone users expect.
New frameworks without delay
Capabilities Apple adds each year can be adopted without waiting for cross-platform support.
Privacy by design
Keychain for secrets, App Transport Security, minimal permissions and accurate privacy labels.
Fewer review surprises
Submissions are checked against the App Review Guidelines before they go in, reducing avoidable rejections.
Accessibility built in
Standard SwiftUI components support VoiceOver and Dynamic Type with little extra work.

How it works
How a booking works in an app for iPhone
An example from a salon and spa chain, where native iOS features make each step feel at home on an iPhone.
- App for iPhone
Step 1: Client signs in
Sign in with Apple or a phone OTP takes a couple of taps, and clients can delete their account from settings, as Apple requires.
- App for iPhone
Step 2: Picks a service, stylist and time
Screens follow iPhone conventions such as swipe-back, dark mode and larger text settings, so booking feels familiar from the first tap.
- Payment gateway
Step 3: Pays by UPI or card
Salon services happen in the real world, so the app can take payment through a gateway such as Razorpay rather than Apple’s in-app purchase.
- Live Activity
Step 4: Sees the appointment on the lock screen
On the day, a Live Activity shows the time and stylist on the lock screen, and a notification arrives if anything changes.
- Front-desk iPad
Step 5: Checks in at the salon
Staff see the arrival in the salon’s admin panel on an iPad and mark the service as started.
- App for iPhone
Step 6: Rates the visit and rebooks
After the visit, the client rates the service and can rebook the same stylist in one tap.

Plain-English glossary
iOS terms, in plain English
- Native iOS app
- An app written in Swift with Apple’s own frameworks. It can adopt new iPhone features as soon as Apple releases them and follows Apple’s design conventions closely.
- Cross-platform option
- A single Flutter or React Native codebase that produces both the iPhone app and the Android app. It lowers cost when you need both, though Apple-only features such as widgets and Live Activities still need some Swift.
- App Store review
- Apple checks every new app and update against its guidelines before release, usually within a day or two. Missing account deletion or unclear permission prompts are common reasons for rejection.
- In-app purchase
- Apple’s own payment system, generally required for digital content and subscriptions used inside the app. Physical goods and real-world services, like a salon visit, can use a payment gateway instead.
- TestFlight
- Apple’s service for installing test versions of your app on your team’s iPhones before release, so you can try real builds and report problems early.
- Privacy label
- The summary on your App Store page of what data the app collects and why. It must match what the app, and every SDK inside it, actually does.
Product preview
What the app looks like on iPhone
Illustrative screens from a salon and spa booking app for iPhone, and the salon’s admin panel on an iPad.
Client app for iPhone. Clients browse services with prices and durations in a layout that respects iPhone text sizes and dark mode. 
Client app for iPhone. Booking shows each stylist’s real availability, and payment goes through a gateway because the service takes place at the salon. 
Lock screen Live Activity. On the day, a Live Activity keeps the appointment on the lock screen, so clients arrive on time without opening the app. 
Salon admin on iPad. The front desk checks clients in and manages the day’s bookings on an iPad, kept in sync with the app for iPhone.

Cost drivers
What drives iOS project cost
Device coverage
iPad layouts, Apple Watch companions and widgets are separate design and build work.
In-app purchases
StoreKit subscriptions need server-side transaction verification, entitlement logic and store configuration.
Apple-only frameworks
HealthKit, Live Activities, App Intents and background modes each add implementation and review work.
Custom interface depth
Bespoke controls and animation need extra work to keep VoiceOver and Dynamic Type support intact.
Android parity
A matching native Android app adds a second client codebase to design, build and maintain.
Estimates are written from your scope, with the effort and assumptions behind each line item.

FAQ
Frequently asked questions
Do we need an iOS app if most of our users are on Android?
Not always. If your audience is mainly delivery partners, field staff or price-sensitive shoppers, an Android app plus a good mobile website may be enough at first. If you sell premium products, financial services or B2B tools used by senior decision-makers, iPhone users can be a large share of paying customers despite fewer downloads. Your own analytics settle it, and we review them with you.
Can our iOS app accept UPI and Razorpay payments?
For physical goods and real-world services such as deliveries, bookings and consultations, yes: gateway SDKs such as Razorpay support UPI, cards and net banking on iOS. UPI app hand-off behaves differently on iOS than on Android, so we test those paths separately. Digital content, premium features and subscriptions used inside the app generally have to use Apple's in-app purchase under the App Review Guidelines.
How long does App Store review take, and what if the app is rejected?
Reviews typically finish within a day or two, though first submissions and complex apps can take longer. Rejections usually cite a specific guideline, such as missing account deletion, unclear permission prompts or login requirements. We check for common issues before submitting, provide demo accounts and review notes, and when a rejection happens we fix the issue or respond through App Store Connect.
Whose Apple Developer account should the app be published under?
Yours. We recommend enrolling your company in the Apple Developer Program as an organisation, which requires a D-U-N-S number, so the app listing, certificates and customer data stay under your ownership. We are added as team members with the access we need. The same applies to Google Play if you also have an Android app, so switching vendors never means losing your app.
