Overview

iOS app development for iPhone users who expect an app to feel right

iPhone users judge an app in seconds: does it feel like iOS, is it fast, does it ask for permissions at a sensible moment. We design, build and publish iOS apps that pass those tests and get through App Store review.

We build with React Native, so the same code can later serve Android users as well. When a feature needs Apple’s own frameworks, we write that part in Swift.

Book a call

  • Native navigation, gestures, dark mode and text size settings, so the app feels at home on an iPhone.

  • The Apple features your users already trust, set up and tested on real devices.

  • Developer account, screenshots, privacy details and review, then an update for each new iOS version.

Why Softclaire

An app Apple approves and iPhone users keep.

Rejections and one-star reviews come from the same few things: crashes, unclear permission requests and screens that ignore iOS habits. We plan for each of them.

Tell us about your app

  • Built to pass review

    We check the app against Apple’s guidelines before submission: sign-in rules, privacy details, purchase rules and what the reviewer will try.

  • Feels like iOS

    Gestures, navigation, haptics, dark mode and text size settings follow iOS, so users don’t have to learn your app.

  • Tested on real iPhones

    Every sprint is tested on actual devices and recent iOS versions, not just the simulator.

  • Your developer account

    The Apple developer account, certificates and the app are in your name, so you can move to another team whenever you like.

What we build

What we build into iOS apps

The iOS features users notice most, and how we use them.

  • Sign in with Apple

    One-tap sign-in that keeps the user’s e-mail private, and the account rules Apple’s review expects.

  • Push notifications

    Order updates, reminders and messages, sent at the right moment and easy to switch off.

  • Apple Pay and in-app purchases

    Payments and subscriptions that follow Apple’s purchase rules, so review doesn’t stop on them.

  • Offline use and sync

    The app stays useful without a signal and catches up with the server when the phone is back online.

  • Camera, scanning and files

    Photos, document scans, barcodes and file sharing, with the permission prompts written in plain words.

  • Widgets and update tracking

    Home screen widgets written in Swift, and download and crash numbers watched after every release.

Process

How an iOS app project runs

Short cycles, with a build on your iPhone from the first weeks.

  1. Plan and design

    We agree what the app does for iPhone users, design the screens to Apple’s conventions and try a prototype on a real phone.

  2. Build with TestFlight

    Every two weeks you get a new build in TestFlight to try on your own iPhone and share with testers.

  3. Submit and publish

    We prepare the listing, screenshots and privacy details, submit the app and handle any questions from review.

  4. Update with iOS

    We keep the app working with each new iOS version and add features based on what users do.

Testimonials

What our clients say

Reviews from founders and teams we have built products with, also published on Clutch and TechBehemoths.

  • TechBehemoths

    Softclaire is development company unlike (many) others. Friendly and flexible, good with deadlines and trustworthy. Experts in multiple fields. We are very happy to work with them as development partner. Very much recommended!

    Arno Bakker Co-owner at Mediascape
  • TechBehemoths

    We have been working with Softclaire for almost 2 years now, on our main product - an online gaming website, play-games.com. Being in the web games niche, things change fast so we need to adapt on the go - and we can trust them with this. They are easy to work with, proactive, and manage work flow very well. We value their transparency and their perseverance in every task they undertake.

    Stefan Naghi Co-founder at FIRST PIXEL SRL
  • TechBehemoths

    We approached Softclaire with nothing more than an idea and a few initial mockups for our SaaS product. Their team stepped in guiding us through strategic planning, development and devops. We are still working with them for ongoing maintenance and feature updates. If you're looking for a reliable, long-term technical partner, I highly recommend them.

    Alexandru Mihalache
  • Clutch

    Within 6 months of our app launch we have gained 750 users. We have had a huge boost in traffic on the platform since launch and have multiple 5 star ratings on the App Store. We have also had comments from other software developers commenting on how brilliant the app is structured.

    Nassouh Kabbani CFO at Pocketask Inc.
  • Clutch

    The team delivered everything on time and provided a mind map to showcase the progress. Overall, they were very flexible and committed to meeting expectations.

    Mihai Brebu Director at Puapi
  • TechBehemoths

    We had an idea for a tech startup in the medical niche, but we lacked the expertise to design and develop a product of this scale. Thankfully we found an amazing team that guided us through the process every step of the way.

    Aron Dumitrache Medtech Innovator
  • TechBehemoths

    A few months ago, I contacted them for a custom Perfex CRM module and the e-Invoice module. Their work is of exceptional quality, and I am extremely satisfied with both the quality and the budget. I highly recommend Softclaire to all businesses and investors!

    Softclaire created a beautiful, functional website for us, exactly as we instructed.

Frequently asked questions

Contact us
How much does it cost to develop an iOS app?
It depends on the number of screens, the back-end behind them and features such as payments or offline use. A focused app is a modest project, one with accounts, payments and an admin panel is a large one. After a short workshop we give you a fixed price per phase. Our guide to what an app costs explains what drives the number.
How long does it take to build an iOS app?
A focused first version takes a couple of months or more, longer with payments, several user types or integrations. We agree the timeline with the scope and put a new build on your iPhone every two weeks.
How long does App Store review take?
Most reviews finish within a day or two, but plan for a few days and for a rejection that needs a fix. We submit early, so review never decides your launch date.
Do I need an Apple developer account?
Yes, a paid Apple Developer Program membership, in your name or your company’s. We set it up with you, so the app, the certificates and the listing belong to you.
Can the same app also run on Android?
Yes. React Native lets one codebase become an iPhone app and an Android one, so the second platform costs far less than starting again. See Android app development, or mobile app development for the whole approach.
Should the app be written in Swift or React Native?
React Native suits most apps and is faster to build for both phones. Swift makes sense for heavy graphics, augmented reality or deep use of Apple frameworks. We tell you which one we would pick, and why, in the estimate.
Can you take over an iOS app someone else built?
Yes. We review the code and the App Store setup first, tell you plainly what is in good shape, then continue the work or rebuild the weak parts. Your developer account stays with you.
