In plain words

What does making an app with us look like?

You do not need to know how apps are made. You tell us who will use it and what for; we design it, build it for iPhone and Android, and publish it in the stores.

An app with your brand that they install once and come back to.

You tell us: I want my customers to order or book from their phone.

Notifications that remind them at the right moment.

You tell us: My customers forget about us.

An app for your team: jobs, photos, signatures and maps, even offline.

You tell us: My staff work out in the field.

We publish it in the App Store and Google Play for you.

You tell us: I do not know how to get into the App Store.

That is all it takes from you. The rest is our job.

Does your business need a mobile app?

An app is the right answer when your clients come back often and do the same few things each time. These are the signs.

  • Clients still phone to book or order

    Your team spends the day on the phone for things a client could do in ten seconds on their own.

  • Appointments are missed

    Without a reminder on the client's phone, people forget, and an empty slot is money lost.

  • Regular clients drift away

    Nothing keeps your business in front of the people who already like it, so a competitor gets the next visit.

  • Updates go out by message, one by one

    Order status, opening hours, offers: your staff type them again and again instead of the app sending them.

Not sure an app is the answer? We will tell you.

Sometimes a fast mobile website does the job. The free analysis tells you which one your clients need.

What can a mobile app do for your business?

A mobile app puts the things your clients do most often one tap away on their phone, and lets you reach them there with the right message at the right moment.

  • Book and order on their own

    Appointments, tables, deliveries or repeat orders, made in seconds at any hour without a phone call.

  • Reminders and updates

    Notifications for appointments, order status and offers, sent automatically to the people who want them.

  • A reason to come back

    Their history, their saved details, their loyalty points: everything that makes your business the easy choice next time.

What kind of app can we build for you?

Apps for your clients and apps for your own team, on their own or as part of a platform we build for you.

  • A delivery rider checking the next order in the courier app

    Booking apps

    For clinics, salons, studios, garages and restaurants: services, free slots, booking, reminders and cancellations, all from the phone.

  • Ordering apps

    Repeat orders, deliveries and pick-ups, with payment in the app and status updates as the order moves.

  • Customer and loyalty apps

    Accounts, history, points and offers that keep regular clients coming back.

  • Apps for your team in the field

    Jobs, routes, photos, signatures and checklists for technicians, drivers and staff away from the office.

  • Apps for a platform or SaaS

    The mobile side of a business platform or subscription software we build for you.

Not sure which of these you need? That is what the free analysis is for.

What sits behind a mobile app?

The app on the phone is the visible part. Behind it, a server keeps the accounts, the bookings and the orders, sends the notifications and talks to your other tools. We build and run that part too.

  • A booking made in the app appears on your team's calendar and on your website at the same moment.
  • Payments in the app go through established providers, set up properly through online payments setup.
  • Every connection is documented and watched, so the app keeps working when the tools around it change.

  • Bookings and orders

Native or cross-platform: which is right for your app?

You do not need to decide, or even know the difference. We choose the way to build that fits your app, your budget and how it will grow, and explain the choice in plain words. What matters to you is that it feels fast and natural on both iPhone and Android.

  • One app experience on iOS and Android
  • Fast, smooth and natural on each phone
  • Built on established, widely used technology
  • Easy for any good developer to continue later

How does mobile app development work?

Four stages, each one ending with something you can see, tap and keep.

  1. Step 1

    The free analysis

    Who uses the app, what they do most, and whether an app or a website is the right answer. We say so if it is the website.

    You receiveA written scope in plain language, and an offer

  2. Step 2

    We design it

    Every screen designed and made clickable on your own phone before anything is built, so you feel the app first.

    You receiveA clickable design you can try on your phone

  3. Step 3

    We build the app and the server

    The app for iOS and Android and the server behind it, delivered in short rounds you test on your own phone.

    You receiveTest versions on your phone throughout

  4. Step 4

    We hand it over and keep it running

    You receive the finished app ready to publish, with clear instructions. The server, data and security stay with us.

    You receiveReady-to-publish app builds, code and a running server

How much does it cost to build a mobile app?

We do not print a price, because apps differ more than any other kind of project. These are the things that decide it.

  • What the app does

    The number of screens and actions, and which phone features it uses, such as camera or location.

  • Who uses it

    Your clients, your team, or both, with different views for each.

  • The server behind it

    Accounts, data, notifications and the connections to your other tools.

  • Payments in the app

    Taking money in the app adds payment flows and their security.

  • Running it afterwards

    Hosting, scaling, backups and security for the server, as a monthly plan on our cloud.

  • Get a written offer for your app.

    Tell us what your clients should be able to do. After the free analysis you receive a scope and an offer.

Your business, on your customers' home screen.

Tell us who would open the app and why. We show you what it would do, how it would look, and how it gets into the stores.

  • One app for iPhone and Android
  • Published in both stores, under your name
  • Data hosted, protected and backed up

How do you choose an app development company?

Four questions worth asking any team before you sign. These are our answers.

  • Will they tell you if you do not need an app?

    We will. If a fast website serves your clients better, you hear it in the free analysis, before you spend anything.

  • Is the app in your name?

    The code, the developer accounts and the data are yours from the first day.

  • Is there a written scope first?

    Always. You approve what will be built and what will not, and every change is agreed before it is made.

  • Who runs it after launch?

    The same team that built it keeps the server, the data and the security running.

Want these answers in your contract? Ask for a quote.

Who runs the servers, data and security behind the app?

We do, as part of the complete package. An app is only as good as the server behind it, so we build it, host it on our own infrastructure, scale it when your clients arrive and protect their data. One team answers for the whole thing.

Infrastructure and cloud

  • The server, hosted by us

    Accounts, bookings, orders and notifications run on servers we manage in Europe.

  • Ready when clients arrive

    A campaign or a busy season brings more people at once; the server grows to meet them.

  • Data backed up

    Client data copied automatically to a separate place, and tested so it restores.

Cyber security

  • Secure logins

    Accounts, passwords and saved logins handled properly, with authentication designed in.

  • Clients' data protected

    Personal data encrypted in transit and at rest, handled the way European rules expect.

  • Watched and updated

    Security updates applied to the server and attacks watched for, before your clients notice anything.

One team for the software, the cloud and the security. Ask what it would cost for you.

Let us put your business on your clients' phones.

Contact sales with a few lines about what the app should do. We come back with questions, then a scope and an offer.

What do you receive at the end?

A finished app, ready for you to publish, and everything around it running.

  • The iOS and Android app, ready to publish
  • Clear instructions for publishing it in the App Store and Google Play
  • The server behind the app, hosted and running
  • The full source code, in an account you own
  • The designs of every screen
  • Documentation another developer could pick up
  • Hosting, backups and security for the server

Want this list for your own project, in writing?

What happens after you contact us?

No sales script and no pressure. Four simple steps, and you can stop after any of them.

  1. You send a few lines

    Through the contact page, in your own words. No form full of technical questions.

  2. We reply with questions

    A person who would work on your project reads it and asks what we need to know.

  3. A call when it suits you

    We talk about your business, not about technology. You can stop there if it is not right.

  4. A written scope and an offer

    Yours to keep and compare, whether or not you go ahead with us.

Technologies and platforms we work with

Established platforms, chosen for what your project needs, so nothing you depend on is an experiment.

The words on this page, explained

Software comes with its own vocabulary. Here is what the terms mean, in plain words.

Everything else we do for businesses like yours

One team for the software, the cloud under it, its upkeep and the customers it brings. Most clients start with one service and add the next.

Not sure which service you need? Tell us the problem and we will point you to the right one.

Questions owners ask us first

If yours is not here, ask it on a call. You get a straight answer from the person who would do the work.

Did not find your question? Ask it on a call.

How much does it cost to build a mobile app?

It depends on what the app does, who uses it and the server behind it, so we do not print a price. After the free analysis you receive a written offer for a defined scope.

Do you build for both iOS and Android?

Yes. Your app works on iPhone and on Android phones, and feels natural on each.

Native or cross-platform?

We choose what fits your app, your budget and how it will grow, and explain why in plain words. You do not need to decide.

Do you publish the app in the App Store and Google Play?

No. We hand the finished app over ready to publish, with clear instructions, and publishing is done under your own developer accounts.

Can the app be part of a platform you build for us?

Yes. Apps can stand on their own, or be the mobile side of a business platform or subscription software we build.

Who runs the server behind the app?

We do, on our own cloud infrastructure, with scaling, backups, monitoring and security included.

Do I need an app, or is a website enough?

If your clients visit once, a fast website is usually enough. If they come back often to book, order or check something, an app earns its place. The free analysis tells you which.

Who owns the app?

You do: the code, the developer accounts and the data, from the first day.

Starting costs you nothing.

The only thing it takes is a few lines about your business. Everything below holds whether or not we work together.

The analysis is free

One conversation and a written scope, at no cost.
