What is iOS App Development?

iOS app development is building apps for iPhone and iPad and publishing them on Apple's App Store. Doon Digital builds iOS apps in Dehradun and has two live on the App Store: Maintainly, a home maintenance app with a home-screen widget, lock-screen actions and offline sync, and Kapy Notes, a notes app with on-device voice transcription and a one-time in-app purchase. We cover design, development, App Review and the updates that follow.

The Problem

You need an iPhone app people will actually keep, but most of what makes that happen is invisible in a mockup: notifications that arrive when promised, an app that still works on a train with no signal, a purchase flow Apple approves, and an update ready when the next version of iOS lands.

Our Solution

We design and build your iOS app, test it on real iPhones, take it through App Review and keep it current afterwards. The team building yours has already shipped Maintainly and Kapy Notes to the App Store, with widgets, lock-screen actions, offline sync and in-app purchases working in production.

Maintainly

Home maintenance app for iPhone

Stop small fixes becoming big bills.

Maintainly turns scattered home upkeep into one prioritised plan and reminds people in time, so a $12 filter never becomes a $4,000 repair. It is built for homeowners in the US, UK, Australia and Canada.

iOS
  • App StoreFree to download, with an optional Pro plan
  • 50Maintenance tasks in the built-in library
  • 4Countries, each with its own climate rules
  • OfflineWorks without a connection, syncs later

Built for iOS

  • A home-screen widget showing the Maintenance Score and the next task due.
  • Lock-screen reminders with Mark done and Snooze actions, so a task can be closed without opening the app.
  • Reminders fall back to local notifications automatically when a connection problem would otherwise have silenced them.
  • Photos attached to tasks and documents are kept in storage iOS cannot clear, rather than in a cache it can.
  • Freeze warnings for pipes and outdoor taps, with no location permission needed.
  • Version 1.0 shipped in June 2026, with two feature releases following by July.

Across the product

  • A starter plan built during a two-minute setup from the home's type, location and equipment, with a Maintenance Score that climbs as tasks get done.
  • Offline-first: tasks are added and completed on the device and sync when the connection comes back.
  • A shareable PDF Home Report with the score, equipment and warranty details, recorded spending and a dated maintenance history.
  • Guest-first onboarding, so nobody needs an account to start using it.
  • Climate and country aware: Australian postcodes resolve to the right climate, so Brisbane is never asked to winterise, and autumn tasks arrive in March.

Kapy Notes

Notes with built-in calculations

Notes that do the math.

A calm notebook for lists, journals and plans where answers appear only on the lines that need them. Write a budget in plain words and the totals, units and currency conversions show up in a slim rail beside it.

Built for iOS

  • On iPhone and iPad through the App Store, with Pro sold as a one-time in-app purchase that needs no account.
  • On-device transcription using the speech recogniser Apple ships. It gives up on anything longer than about a minute, so long recordings are fed to it in pieces cut at pauses, and no word is ever split.
  • Exports open the standard Save to Files sheet instead of writing into an app folder nobody was told about.

Across the product

  • Inline calculations with variables, units, percentages and currency conversion, answered in a rail beside the lines that ask.
  • Local by default. Sync is optional and end-to-end encrypted with a passphrase only the user knows.
  • Voice notes transcribed and summarised on the device with no account and nothing leaving it, or in the cloud on devices that cannot do it themselves.
  • Shared notes, with collaborators shown by name and picture rather than by email address.
  • Numbers follow the device's region, so a device set to India counts in lakh and crore rather than millions.

What We Offer

An iPhone app is judged in its first minute: how quickly it opens, whether it demands an account before it has earned one, and whether its notifications are useful or just noise. We build iOS apps that pass that test, and we have two on the App Store to show for it. Maintainly is our home maintenance app for iPhone. It builds a personal plan during a two-minute setup, puts the Maintenance Score and the next task on the home screen with a widget, and lets people mark a job done or snooze it straight from a lock-screen reminder. It works offline and syncs later, and when a connection problem could have silenced a reminder, it falls back to a local notification instead. Kapy Notes runs on iPhone and iPad alongside Android, Mac and Windows. On iOS it transcribes voice notes on the device using the speech recogniser Apple provides, feeding long recordings to it in pieces cut at pauses, and it sells Pro as a one-time in-app purchase that needs no account. Details like these are what separate an app people keep from one they delete.
