App Development
TitApeX designs and builds iOS and Android apps for brands and startups. Planning, UI/UX design, engineering, store submission and maintenance are handled by one team, so you never have to relay messages between a design studio and a development shop.

You know the problem you want to solve but not where to start. We turn the idea into a specification that can be built.
You already have a website and customers, and need membership, booking or subscriptions to bring them back.
Text understanding, image recognition or on-device models call for a team that knows both AI and product experience.
The experience is dated and the code is hard to maintain. You want a redesign on a stable foundation.
Every stage of taking an app from nothing to launch is done by our own team.
We define the target users, the core features and the scope of version one, so nothing unused gets built.
From user flows and wireframes to full interfaces, following iOS and Android platform guidelines.
Native or cross-platform, chosen to fit the product and the budget.
Accounts, database, push notifications, and an admin panel for your day-to-day operations.
On-device models or cloud language models, with privacy and data protection designed in.
App Store and Google Play submission, version updates and compatibility with new OS releases.
The hard part of putting AI in an app is not connecting a model. It is deciding what the AI should handle, where the data stays, and what happens when there is too little to go on. We have solved these in our own shipped product.
We use on-device models such as Apple Intelligence, so content never has to leave the phone and users need no setup.
We integrate models from OpenAI, Anthropic and others, with keys supplied by the user or managed by your backend.
Before content is sent, keys, phone numbers, emails and other sensitive data are masked on the device. Keys stay in the device keychain.
Output follows a fixed structure. When the input is too thin, the app says so instead of letting the model guess.
We learn your business goals, users and budget, and agree on what version one must do.
We prepare the feature list, timeline and quote. Work starts only after both sides agree.
We plan the flows and interface, and confirm the experience with a clickable prototype.
We deliver installable test builds in stages, so you can see progress at any time.
We prepare the store listing and privacy details, submit the app and handle review feedback.
We monitor, fix and update the app, and plan next steps from real usage.
We build apps for clients, and we also design, build and ship our own.
From the iPhone share sheet, hand it a sentence you can't parse, an error message or a screenshot, and it returns an explanation in a fixed structure that you can keep questioning. It uses Apple's on-device model by default and masks sensitive data before anything leaves the device. No ads, no trackers and no account.
Every app differs in features, platforms and integrations, so we quote each project instead of publishing fixed prices. Tell us the following and you will get an accurate estimate sooner.
Share your brief for a quoteIt depends on scope. A focused first version usually takes a few months, and products with accounts, payments or AI take longer. Our quote includes a timeline by stage.
It depends on where your users are. On a limited budget we usually suggest proving the product on one platform first. If you need both, we can evaluate cross-platform development.
Yes. Discovery and specification are the first step of our process. We turn your idea into a feature list and a scope for version one.
Yes. Store copy and screenshots, privacy details, submission and replies to review feedback are all part of the process.
Yes. Our own app on the App Store is built around an on-device AI model. We recommend on-device or cloud models based on the feature, cost and privacy needs.
Yes. Operating systems update every year and third-party services change. We provide maintenance and version updates so the app keeps working.
Yes. We take projects in Taiwan and abroad, including Dubai and Europe. We work in English or Chinese, and the whole process can be remote.
Native apps are written separately for iOS and Android and give the best experience and system integration. Cross-platform apps share one codebase and cost less. We recommend native when the product needs deep system features such as share extensions or on-device AI.
Apple and Google set the review time. Most reviews finish within a few days, and a rejected build must be fixed and resubmitted. Our timeline allows for review and revisions.
Check three things: whether the team has shipped apps of its own, whether the quote maps to a clear feature list, and who maintains the app after launch. Projects go wrong when these are unclear.
Tell us what you want to build and we will reply with an approach, a timeline and a quote.
