What Is App Development?

App development is designing, building and releasing applications for mobile. An app lives on the customer's home screen, can send notifications, work offline and use the phone's camera, GPS and payment solutions. That makes it the strongest tool for services people use often.

We take the whole journey: needs assessment, design, development, testing and submission to the App Store and Google Play, with maintenance and further development after launch. We choose the technology for what the app should do, not for what is easiest for us. You get one partner from idea to published app. A full-scale example is Bestpris.no, which we developed and operate.

Do You Actually Need an App?

Honest answer: not always. An app costs more than a web solution and has to be downloaded before it gives any value. Our rule of thumb is simple.

Choose an app when users come back often, need notifications, or should use the phone's features such as the camera and GPS. Choose a web application when the solution is used less often or mostly from a PC, such as customer portals and booking systems. We build those through web development.

If you are unsure, we help you choose in the first meeting, before you have spent a dollar. Sometimes we recommend dropping the app. Then you have saved money, and we have gained one more honest customer.

The Best Tools Are Built Around the Way You Work.

Built for the Users

We design the app around the way it will actually be used: short sessions, clear choices and no unnecessary steps.

Tested All the Way

We test as we go, not at the end. That is when mistakes are still cheap to fix.

Maintained After Launch

An app that is in use has to be maintained. We follow up with updates and support once it is out.

Always Included

No hidden extras. This is the foundation of every delivery.

  • Needs Assessment

    We work out what the problem actually is before we propose what to build.

  • Design and Prototype

    You see how the solution works before it is finished, so changes cost little.

  • Development

    Apps for iOS and Android, with technology chosen for your need, not out of habit.

  • Integrations

    We connect the solution to what you already have, such as CRM, payments, booking or accounting.

  • Testing

    Unit testing, integration testing and user testing throughout the process.

  • Release

    We handle submission, requirements and approval in the App Store and Google Play.

  • Maintenance and Support

    Updates, improvements and help when something stops working.

From Problem to Solution

01 Phase 1

Consultation

We go through the need and what the solution should do. If you do not have a finished idea, we help you shape one.

02 Phase 2

Plan and Design

We make a plan and design the solution, so you see what you get before we build.

03 Phase 3

Development and Testing

We build and test in parallel, with unit testing, integration testing and user testing.

04 Phase 4

Launch and Maintenance

We launch the solution and follow up with maintenance, updates and support.

Tools We Have Built Ourselves

The best proof of what we can deliver: our own products, in daily use across thousands of websites.

«Etter å ha brukt veldig mye penger på ulike webdesignere, uten å få et tilfredsstillende resultat, ramlet jeg tilfeldig bort i Mementor. Det ble rene lottogevinsten.»

Frequently Asked Questions

Wondering about something else? Ask your question here. We answer within one working day.

What kind of solutions do you develop?

We develop mobile apps for iOS and Android, from idea and design to release and maintenance. We also build apps as products, such as our tools for WordPress. If you need a customer portal or a booking system, we build that through web development.

What technology do you use?

We choose the technology for the project, not out of habit. That may be native or cross-platform for apps, and modern frameworks on the web. We always explain why.

How do you ensure the solution is good quality?

We test throughout the process, not just at the end: unit testing, integration testing and user testing. Mistakes caught early are cheaper to fix.

What if I do not have a clear idea yet?

That is perfectly fine. We help you shape and sharpen the idea, whether it is an app or a web solution. The best projects often start with a problem, not a solution.

What does it cost to develop an app?

The price depends on three things: how many screens and features the app needs, whether it should have login and connections to other systems, and how much is built specifically for you. A simple app costs a fraction of a large platform. You get a fixed price before we start, with no hidden costs, and we say so honestly if a web solution covers the need for less.

How long does it take to build an app?

A simple app usually takes one to two months from the first meeting to release, larger solutions longer. Approval in the App Store and Google Play normally takes a few days and is part of our plan, not a surprise at the end.

Who owns the app and the code?

You do. Once the project is delivered and paid for, you own the design, the code and all the content. You are free to develop the app further with us or with anyone else.

Price

A Fixed Price, Agreed Before We Start

You get a fixed price for the whole project before we write a line of code. Full transparency, no hidden costs and no hourly-rate surprises. After launch we offer maintenance and further development through a Service Level Agreement (SLA), which runs month to month with no lock-in.

  • Fixed project price agreed up front
  • You own the app and the code when it is delivered
  • Maintenance after launch, with no lock-in
