Our iOS app development team designs, builds and launches custom iPhone and iPad apps for businesses, churches, nonprofits and founders. Your app comes from the same team that publishes its own apps on the App Store.
Updated November 12, 2026
As an iPhone app development company that also builds and manages websites, we build custom iOS apps for businesses, churches, nonprofits and founders. Here are common kinds of iPhone and iPad apps and the features people usually want in each. Yours can mix and match.
Your own app for customer accounts, quotes, orders and service requests, connected to the systems you already run, for small businesses and enterprise teams alike.
Job lists, inspections, checklists, photos and time tracking for crews in the field, synced back to the office.
Appointment requests, visit reminders, check-in and care instructions for practices, clinics and wellness providers.
Class schedules, workout plans, progress tracking and member check-in for gyms, studios and coaches.
Menus, order ahead, pickup and delivery updates, and rewards that bring your regulars back.
Your catalog, checkout, order tracking and member offers in an app your best customers keep on their home screen.
Searchable listings with photos, maps, saved favorites and showing requests for brokers, agents and property managers.
Appointments for salons, coaches, tutors and service businesses, with reminders and easy rescheduling.
Sermons, events, giving links, prayer requests and check-in in one church app, from a team led by a senior pastor.
Member directories, event registration and check-in, volunteer sign-ups and donation links in one place.
App development for startups: a focused first version, tested with real users on TestFlight, then launched on the App Store.
Puzzle, word and multiplayer games with leaderboards, achievements and rewards, like the games we publish.
Already have a website? We can turn it into a native iPhone app that shares its content and adds what only an app can do, like push notifications, saved accounts and offline access. Apple can reject apps that simply repackage a website, so we build the real thing.
Each one is published by CalTech Web on the App Store, so you can download it and try our work for yourself. Under each app is what the same work can do in an app built for you.
Puzzle game · iPhone
An undersea block puzzle with more than 230 levels, where a crew of crabs carries blocks home to their burrow.
For your app: The same tools can power loyalty points, member badges and progress that follows a customer from one device to the next.
Multiplayer word game · iPhone and iPad
A live crossword for two to eight people on one board. Friends join with a link or a six-character code, from the app or a browser.
For your app: The same live sync can run a shared job board, a volunteer schedule or a team checklist that everyone updates at once.
Logic puzzle · iPhone and iPad
A tile-rotation puzzle with 1,000 levels that all play offline, plus head-to-head races between friends.
For your app: The same offline design keeps inspections, checklists and forms working where there is no signal.

Here is how to make an app for your business with us: five steps from first call to App Store, with a working build on your own phone long before launch day.
A 30-minute call with Brandon about your app, who will use it and what it needs to do on day one.
What the app will do, in writing, with a quote, before any work starts.
As features land, you install test builds on your own iPhone through Apple's TestFlight and tell us what to change.
We prepare the listing, screenshots and privacy details, submit the app to Apple and answer review questions.
An optional support and maintenance plan keeps your app working with each new iOS release. New features are quoted as you need them.
iOS app development cost depends on what your app needs to do, so we do not publish a price list. We quote each app from a written scope, and you see the quote before any work begins. App builds are quoted separately from our $99/month website plans.
The fastest way to a number is a short call. Tell us what the app needs to do and we will help you find a first version that fits your budget, then add to it once real people are using it.
