UI/UX Design for Mobile

UI/UX Design for Mobile

Design your developers can actually build.

Flows, screens, a clickable prototype and a design system, designed by the team that also builds apps, so nothing gets handed over that cannot be built.

Built by the person you will actually talk to

I am Anand Yadav, founder of SightInfusion. I have been building mobile apps for over 7 years and I have personally delivered more than 52 of them: idea, design, development, store submission, the whole thing.

That is why I care about this page more than most. I have been on the other side of a bad handover: beautiful screens, and no answer for what the app does when the list is empty or the network drops. Somebody has to build it afterwards. Usually that was me.

So when we design for you, I am on the call, and I am the one who says whether something can actually be built.

What usually goes wrong

What clients say, and what it actually means

“It looks fine to me.”

What it means

It was tested on one screen, one thumb, one person: the client's.

“Just make it look more premium.”

What it means

Premium is a set of specific decisions, not a mood.

“The designer said it would take two weeks.”

What it means

Two weeks covered the screens, not the states in between them.

What you actually receive

Most design agencies describe the work. Here is the list of things that are yours at the end of it.

DeliverableWhat it is
User flows and structureEvery path through the app, mapped before a screen is drawn
WireframesThe layout of every core screen, agreed before any visual design
Final UI screensiOS and Android, at real device sizes
A clickable prototypeThe whole app, tappable, testable with real users before a line of code
A design systemComponents, colour, type and spacing: the rules, not just the screens
Developer handoff packEvery state, spacing rules, named tokens, assets at every density. See section 7
The source filesYou own the Figma files and everything in them
A walkthrough with your engineersA recorded session so the people building it heard it from us

If any of these is missing at handover, the project is not finished. That is our standard, not an upsell.

Your developers will be able to build it

The most common way a design project fails is not ugly screens. It is a handover the engineers cannot use.

So here is exactly what your developers get:

What they getWhat that means
Every state, not just the happy oneLoading, empty, error, offline, no-permission, first-run
Spacing and sizing rulesWritten down, not guessed from the file
Named tokensColour, type and spacing as values your code can hold
A spec they can read without a paid design-tool seatExported and annotated. Design tools charge per developer. That should not become your problem
Assets at every densityiOS and Android, ready to drop in
A walkthrough call with your engineersBefore the build starts, not after it breaks

Why we can promise this and a design-only studio cannot: our designers sit with our developers. The people who draw it and the people who build it are the same team, on the same projects, every week.

Your iOS app now looks older than it is

Apple changed how every iPhone app looks.

Since 28 April 2026, any app uploaded to the App Store must be built with Xcode 26 and the iOS 26 SDK. That means it renders in Apple’s new Liquid Glass design by default: translucent materials, tab bars that shrink as you scroll, and app icons that have to be rebuilt in layers.

There is a temporary setting that switches the old look back on. Apple has confirmed it is supported for this Xcode cycle only and will be removed in the next major release.

And 79% of all iPhones already run iOS 26, 86% of iPhones sold in the last four years.

So an app still on the old visual language does not look dated next year. It looks dated to four out of five of your users today.

What we do about it: we redesign for the new design language in stages, starting with the screens your users actually spend time on, so you are not paying for a rebuild you did not plan.

Designing for the hand

A phone screen is a thumb, not a mouse

Reach, tap size, one handed use, and what the screen does on a slow connection. Those are design decisions rather than engineering ones, and they are what the sections below cover.

Designing for AI features

This is the part most design teams have not caught up with yet.

The moment an app has an assistant or an agent in it, the old design rules stop working. You are no longer designing software that always gives the same answer. You are designing something that takes time, is sometimes unsure, and is sometimes wrong. That needs its own design work:

While the AI is thinking

Waiting has to feel like progress, not a frozen screen.

When the AI is not sure

The interface should say so honestly. A confident wrong answer costs you the user's trust permanently.

Before an agent acts

If the app is about to book, pay, send or change something, the user needs a clear moment to approve it.

When the AI fails

Timeouts and errors happen. The app should degrade gracefully and stay useful, never break.

Handing over to a human

When the AI cannot help, the path to a real person has to be obvious.

There is no ready-made template for any of this. It is design work, and we do it.

Process

How we work

Understand

Your users, your product, what the app has to achieve, and what is already known. If you have analytics or store reviews, we read them first.

2 to 3 days

Flows and structure

How someone moves through the app to get what they came for. Agreed before any screen is drawn, because this is the cheap place to change your mind. You keep the structure.

3 to 5 days

Screens

The visual design, at real device sizes. We use AI to explore more directions quickly, then decide deliberately.

1 to 3 weeks

Prototype and test

Clickable and testable, before a line of code exists. Adjusting a wireframe takes hours. Changing live code takes days or weeks. You keep the prototype.

3 to 5 days

Design system

Components and rules, so the next twenty screens are cheaper than the first twenty. Skipped or shortened if you are building a small first version. You keep the system.

3 to 5 days

Handoff

The developer handoff pack, plus a walkthrough call with your engineers.

2 to 3 days

Together, that is roughly 3 to 6 weeks.

Questions buyers actually ask

Can you design without building it?

Yes, and it is a normal way to hire us. You get the full package, you own the files, and your team or another agency builds it.

Should I hire a designer or a developer first?

For mobile, design first, but only as much design as the stage deserves. A first version testing whether anyone wants the product needs flows and a few key screens, not a full system. A product with real users needs the whole thing. We will tell you which one you are.

How long does app design take?

A first version takes 1 to 2 weeks. A full product takes 3 to 6 weeks depending on screen count. A redesign of a live app takes 2 to 4 weeks and can be staged so you ship in parts.

Do we own the Figma files?

Yes. The editable source files, not just exported images. Everything transfers to you.

What if we do not like the first concepts?

Revision rounds are written into the quote before we start, so you know what is included and what happens after that.

Will our developers actually be able to build it?

This is the question we take most seriously. Every state, spacing rules, named tokens, assets at every density, and a walkthrough call with your engineers before the build starts.

What is the difference between UI and UX?

UX is whether someone can get what they came for. UI is what it looks like while they do. A beautiful app nobody can navigate fails; a plain app that works quietly succeeds. We do both, and we do them in that order.

Do we really need a design system?

Often not yet. If you are testing whether anyone wants the product, a full design system is money spent too early. A short set of rules is enough. Once the product is proven and features keep arriving, the system is what stops it drifting.

Our app is live and users drop off. Do we start here?

Probably not. Start with a UI/UX Audit. You get a written report on what is actually costing you users, ranked by impact, before anyone talks about new screens. Then redesign what the report says matters.

Can you redesign our app without breaking it for existing users?

Yes, and this is usually the right way. We stage it: the screens people spend the most time on first, so you ship improvements gradually instead of surprising your users with a new app one morning.

How do you know the design works?

We test the clickable prototype with real users before development, and we agree up front which number the design is supposed to move: signups, completion, retention, store rating. A design that cannot be judged is a decoration.

Can't AI just generate the screens?

Partly, and we use those tools. But the current generation of tools cannot build from your design system, and their own makers do not claim the output is production-ready or accessible. See designing for AI features.

How much of our time will this take?

A kickoff call, one review call a week, and a decision-maker who can actually decide. Design projects stall on approvals far more often than on design.

Who will actually work on our project?

Anand is on the call and makes the technical calls. The team grows with the project. Accountability does not move.
