iPhone and iPad apps built to Apple's guidelines and kept working after launch

iOS app development services cover designing, building, releasing and maintaining an app for iPhone and iPad. At Hashlogics that means a Swift or React Native build, the backend behind it, App Store submission under your own developer account, and updates after each iOS release.

Choose React Native for most business apps, because one codebase serves iOS and Android and the screens use real platform components. Go native in Swift when the app depends on heavy background work, low-level Bluetooth or a demanding camera pipeline. We give you the answer in the Blueprint, before you've paid for either.

Yes. An iPad layout is designed with the app rather than stretched from the phone version, because tablet users often work with more data on screen at once. We settle which devices you support in the Blueprint, since each one adds testing.

Common reasons are crashes or incomplete builds under guideline 2.1, for being a repackaged website under 4.2, and for privacy problems under 5.1.1. Missing privacy policy links, vague permission strings and requests for data the app doesn't need are the usual causes. We test a release candidate against these before submitting.

A privacy nutrition label is the summary of an app's data practices shown on its App Store product page. You answer the questions in App Store Connect, and the answers must cover third-party code in your app. We build the answers from a list of every SDK and update them when the code changes. You don't need a new app version to change them.

Your app needs the prompt only if it tracks users, which Apple defines as linking user or device data collected from your app. Many apps never do, but an advertising or analytics SDK can change that. We audit the SDKs, and if tracking is real we show the prompt at a moment that makes sense to the user.

Yes, if people can create an account in the app. Apple requires that they can start deleting it from inside the app, and temporary deactivation alone doesn't count. The account and its personal data are deleted, except anything you must keep by law, and the app tells people what that is. If you use Sign in with Apple, the flow also revokes the user's tokens. We build the flow and the backend cleanup together.

We test your app against each new iOS release and fix what it changed. That runs under an agreed service level, or your own team takes over after a documented handover. Crash reporting stays on, and the first 2 months of support are included with every build.

You do. We work under your Apple developer account, so you own the listing and the signing keys, and the code and backend accounts are yours in writing before work starts. You can take the app in-house or to another firm at any point.

Yes. We start with the fixed-fee Blueprint: an engineer reads the codebase, runs the app on real devices and reports what is fixable against what should be replaced. The Blueprint fee is credited in full against the build, and if the plan isn't one you'd act on, you don't pay for it.

Cost depends on whether you need iPhone only or iPad too, how much works offline, and how many systems the app talks to. Quoting before an engineer has seen the workflow is a guess. The scoping call is free, and the fixed-fee Blueprint, credited in full against the build, gives you one fixed price per milestone before the build starts.

No. A startup usually wants one workflow on users' phones and evidence it holds up, so we ship narrow and watch the crash reports. An enterprise adds single sign-on, device-management distribution and role permissions. The review and release discipline is the same for both.
