We design and build apps people use every day
AppXcellence Solutions takes iPhone, iPad and Android apps from the first sketch to the App Store and Google Play, then keeps them growing. Our apps for Nice Express have earned more than 6,400 App Store ratings.
How we work
One team, from idea to App Store
Strategy, design, development and launch under one roof. The people who plan your app are the people who design it, write the code and answer your users, so nothing gets lost between agencies.
What we do
Everything a mobile app needs, from the first sketch to the App Store and beyond.
iPhone and iPad apps
Native Swift and SwiftUI apps that feel at home on iOS, with in-app purchases and subscriptions through StoreKit.
Store launch and monetisation
Listings, screenshots and keywords for the App Store and Google Play, App Review handled, and a business model that fits.
UI and UX design
User flows and clickable prototypes you can try on your phone before a line of code is written.
AI features
Practical AI that saves your users time, like HookLab’s video scripts, with a clear word on what data is sent.
Android apps
Kotlin and Jetpack Compose apps for Google Play that share the design of your iOS app.
Maintenance and growth
Updates for every new iOS and Android version, new features and answers to your users, long after launch.

Why AppXcellence
A small senior team that ships
✅ One team from design to launch: no hand-offs, no lost context.
✅ Native code on iOS and Android: Swift and Kotlin, not a web page in a wrapper.
✅ Published, not just built: store listings, review and launch are part of the job.
✅ We stay after launch: updates, new features and support for your users.
Monetisation
Business models that respect users
For Nice Express we have shipped in-app subscriptions and one-time unlocks with StoreKit, ads in free versions with Google AdMob, and fully ad-free apps such as Fince, a budget tracker with no bank login and no account.
What every app we ship has in common
Intuitive
Familiar gestures and clear screens, so users get it right the first time
Flexible
Themes, favourites and settings that adapt to the way people use the app
Creative
Fresh ideas, like an AI that writes video hooks or a remote with a touchpad
Efficient
Fast and light, designed to get users to the result in a few taps
HookLab AI: from a topic to a script
We designed and built HookLab AI for Nice Express: it turns one topic into video ideas, opening hooks and a timed script for TikTok, Reels and YouTube Shorts.
AI that does the boring part
Type a subject and HookLab suggests five video ideas or ten opening lines, each with a strength score, then writes a 30 or 60 second script. Under the hood: SwiftUI, StoreKit and Claude, the AI model made by Anthropic.
Case study · Voice assistants
Siri and Alexa guides with thousands of ratings
Voice Commands for Siri lists more than 500 Siri commands and Voice Commands for Alexa Echo more than 700 Alexa commands, on iPhone, iPad and Android. Built and kept up to date by AppXcellence for Nice Express.
Case study · Smart TV
SmartCtrl: one remote for every TV
For Nice Express we built SmartCtrl, a universal TV remote that finds Roku, Samsung, LG, Fire TV, Google TV and Vizio TVs on the Wi-Fi and speaks each platform’s own protocol: every button, a touchpad, the keyboard and the TV’s apps, on iPhone, iPad and Android. See the SmartCtrl page.
Every platform your users are on
iPhone, iPad and Android, in the languages your users speak.
iOS and Android
SmartCtrl and the Siri and Alexa guides ship on both the App Store and Google Play.
Every language
Localised store pages, six languages in the Siri guide and right-to-left Arabic in Thabat.
AI built in
HookLab and Punch List AI use AI to write scripts and inspection reports in seconds.

A new app, from idea to launch
We clarify the idea with you, design a prototype you can try, build native iOS and Android apps and publish them on the App Store and Google Play.
-
Taking over an existing app
We review the code and the store listing, fix what hurts your ratings first, then ship regular updates and new features.
-
AI features for your app
We add AI where it saves users time, and we are clear about what data is sent and why.
