In short

Mobile app development is the work of designing and building an app that gives customers a reason to return on their phones, and measuring whether it does. MMC builds apps for brands whose customers use them repeatedly, after first checking that an app beats a mobile website. The core journey is built for speed and measured after launch.

  • Only if it earns it. We first ask whether an app is the right answer.
  • One core journey. The main task, made fast and clear.
  • Measured from day one. Events and retention tracked, so the app can improve.

Monday Marketing Company (MMC) builds mobile apps for brands whose customers use them repeatedly.

What app development covers.

Six stages from deciding if you need an app to improving it after launch.

  1. App or website. An honest look at whether an app, a fast mobile site or a web app serves your buyers better.
  2. Core journey design. The few screens that matter most, mapped and prototyped before any build.
  3. Build. Reliable code for the platforms you choose, with regular working builds to review.
  4. Analytics from day one. Events and funnels set up so you learn from the first real users.
  5. Store launch. Listings, review requirements and release steps handled for you.
  6. Improvement cycles. Updates planned from user data and support feedback.

Why brands build apps with MMC

We build apps that connect to your marketing, not apps that sit apart from it.

  • We say when you do not need one. If a better mobile site is the right answer, we will say so.
  • Marketing-aware builds. Attribution, deep links and CRM events are planned into the app.
  • Design and engineering together. One team keeps the design intent through to the shipped product.
  • Useful for any audience. Customer apps for D2C, tools for B2B teams and portals for education.

The work, shown

What we actually do to build your app.

  1. 01

    Decide whether you need an app.

    We compare an app with a mobile site against customer habits, and say so if it is not yet worth it.

  2. 02

    Design the one journey they return for.

    The first release stays focused on a single core task, made fast and clear.

  3. 03

    Build, test on real phones, and measure.

    Testing runs on the phones your customers use, with key events tracked from the first release.

  4. 04

    Launch, then release and improve.

    Store listing and regular releases, guided by active use and retention.

Where it leaks

Five ways an app goes wrong.

App pathTap a number to see where it breaks and how we run it.
Illustrative diagram, not a client account. No real figures.
  1. 1

    App or website

    Building an app because competitors have one.

    An app has real costs, and it only pays if customers use it repeatedly. A fast website is often enough.

    How we run it. We compare an app with a mobile website against your customers' habits, and tell you if an app is not worth it yet.

  2. 2

    UX and flows

    Packing in every feature at launch.

    Apps that try to do everything do the main thing poorly, and users leave.

    How we run it. We design the one journey customers return for, and keep the first release focused.

  3. 3

    Development

    Shipping a slow or unstable first version.

    A poor first experience is hard to recover from, since many users do not return.

    How we run it. We build for speed and stability, with testing on the phones your customers actually use.

  4. 4

    Analytics and retention

    Launching with no tracking.

    Without events and retention data you cannot tell what to fix.

    How we run it. We instrument key events and retention from the first release, and connect them to your marketing data.

  5. 5

    Store launch and releases

    Treating launch as the finish line.

    Store presence and regular releases decide whether an app is found and keeps improving.

    How we run it. We prepare the store listing, plan releases and use what we learn to improve the app.

How the work runs

How we run mobile app builds, step by step.

  1. An app and a website being compared.

    Step 1

    Decide if you need one

    We compare an app with a mobile website against your customers' habits and tell you honestly.

    You get: A clear yes or no, with reasons.

  2. App screens in a core journey.

    Step 2

    Design the core journey

    The one task customers return for is designed and tested first.

    You get: A tested prototype of the main journey.

  3. An app being built and tested.

    Step 3

    Build and instrument

    Development with key events measured from the first release.

    You get: A fast, stable app with usable data.

  4. An app being prepared for release.

    Step 4

    Launch and improve

    Store launch, then releases guided by active use and retention.

    You get: An app that gets better with use.

Timing depends on scope. We agree it with you before work starts.

Apps for brands whose customers return on their phones.

A good fit

Customers would use it repeatedly, such as to reorder, track or learn.

Repeat use is what justifies an app, which suits D2C brands with frequent reorders and education brands with ongoing learners.

Not a fit

You want an app for its own sake, or have no plan for getting installs.

An app nobody opens twice does not pay back, and we will say so before you spend.

Common questions

Questions about mobile app development.

What is mobile app development?

Mobile app development is the work of designing and building an app that gives customers a reason to return on their phones, and measuring whether it does.

How does mobile app development work with MMC?

We first check that an app beats a mobile website for your customers, then design the core journey, build for speed and reliability, instrument key events and improve it after launch.

What does mobile app development cost?

We quote per project, after a call, once the scope is clear: what you need, how much of it, and what it has to connect to. The scope and the fee are agreed in writing before work starts.

Do you guarantee results?

No. We cannot guarantee installs or usage. We commit to an honest view of whether you need an app, a tested design, a stable build and measurement from day one.

Who is mobile app development for?

Brands whose customers will use an app repeatedly. Not only D2C. We work with D2C, B2B and education brands, and set the work up differently for each: D2C on reorders and loyalty, B2B on tools teams use every day, education on portals for students and parents.

What do you need from us?

A clear description of the repeat use, your brand assets, your existing systems and data, and a decision-maker for each stage.
