Hi, I'm Terris. I'm a web designer in Singapore, and I design and code every app myself.

Get an AI mobile app in Singapore that works on every phone from one build

I build AI apps people use on their phones as installable web apps: they work on iPhone and Android from one build, sit on the home screen like an app, and update without an app store review. If yours truly needs to be in the App Store, I'll say so before you spend anything.

What an AI mobile app with me includes

An AI mobile app with me includes a phone-first design, the app built as an installable web app that works on iPhone and Android, the AI features connected to a model, logins and data where needed, and hosting that keeps it fast. You own the code.

  • A design made for phones first
  • One build that works on iPhone and Android
  • Installable to the home screen, like an app
  • AI features connected to a model, with limits on cost
  • Logins and a database where the app needs them
  • Camera and photo upload where the browser supports it
  • Source code you own

How I build your AI mobile app

  1. Check it needs an app

    What people will do with it and whether an installable web app covers it, or whether it truly needs the App Store. I'll tell you honestly.

  2. Design for phones

    Screens designed for thumbs and small screens first, tried on your own phone before the build.

  3. Build it once

    One build that runs on iPhone and Android and installs to the home screen.

  4. Add the AI

    The model connected with clear instructions, cost limits and checks on what it returns.

  5. Launch and update

    Live at a link people can install from, and updated for everyone at once, with no store review in the way.

How much does an AI mobile app cost in Singapore?

AI builds with me start at SGD 6,575, and larger apps with logins and a database at SGD 12,140, fixed per phase. The AI model's running costs are yours and quoted separately. Building it as an installable web app avoids paying twice for separate iPhone and Android versions.

A chatbot on your own content, a workflow that runs itself, a model wired into the tools you already use.

  • Scoped against what your stack already does
  • Fixed price per phase
  • Running costs quoted separately and honestly

Model and hosting costs are yours and are quoted separately, usually SGD 30 to 200 a month.

A larger app with logins and a database

Custom web application

SGD 12,140From

Anything with a login, a dashboard, roles or a database behind it. No tier covers this honestly, so it is sized properly or not quoted.

  • Scoped in hours at SGD 110 to 150
  • One fixed number, extras priced separately
  • A smaller first phase offered where it splits cleanly

Dev shops quote SGD 20,000 to 50,000 for the same MVP because four people bill their part of it.

Questions about AI mobile apps

How much does an AI mobile app cost in Singapore?

With me, AI builds start at SGD 6,575 and larger apps at SGD 12,140, fixed per phase. Model running costs are separate and quoted before you commit.

Should I build for iOS, Android or both?

Both, from one build, if an installable web app covers what you need. It runs on iPhone and Android, which together cover nearly every phone in Singapore.

What is an installable web app?

A web app that people can add to their home screen and open like an app, full screen, without going through an app store. It updates for everyone at once and works on any modern phone.

When does an app need to be in the App Store?

When it needs features a web app can't reach well, such as some background tasks or deep device integrations, or when being in the store matters for how customers find you. If that's your case, I'll tell you up front whether I'm the right person to build it.

Can the app use the phone camera for AI features?

Yes, for things like snapping a photo for the AI to read or check. Browsers on iPhone and Android give web apps access to the camera with the user's permission.

What's the difference between on-device AI and cloud AI?

Cloud AI sends the request to a model on a server, which is more capable and easier to update. On-device AI runs on the phone, which is more private and works offline but is more limited. Most business apps use cloud AI.

Can the app take payments?

Yes. A web app can take cards, PayNow and wallets through a gateway like Stripe or HitPay, without the app store's cut on in-app purchases.

Do I own the app?

Yes. You own the code and everything I make for it, documented so another developer could pick it up.

Tell me what people would do with it

Describe the app on WhatsApp, and I'll tell you whether a web app covers it and what a first phase might cost.
