Trackfellow AB
Train like a pro with Trackfellow
We build comprehensive, data-driven mobile apps for iOS and Android. From concept and design to publication on the App Store and Google Play.
We provide everything needed to take your mobile app from concept to launch - design, features, integrations, security, and publication on the App Store and Google Play.
Wireframes, prototypes, and screenshots that are validated with real users before a single line of code is written.
iOS (Swift), Android (Kotlin), or React Native—we recommend the option that best fits your budget and timeline.
Scalable server architecture, databases, and REST/GraphQL APIs that can keep up as you grow.
BankID, Swish, Stripe, ERP systems, CRM - we integrate the app with your existing infrastructure.
We handle the entire publishing and certification process and ensure that the app is approved quickly.
Ongoing maintenance, performance monitoring, and security updates after launch.
Here is a selection of the mobile apps and systems we have developed for Swedish companies. Every project is unique - just like the business challenges we’ve solved.
Book a free call and we’ll go through your app idea together — including the features you need, which technology is the best fit, and what budget level is realistic.
We’ll help you understand what affects the cost, which parts should be prioritized first, and how to move forward in a smart way.
Tell us briefly about your needs, and we’ll develop a customized plan and a quote that fits your budget, your goals, and your timeline. No obligation.
Here, we answer the questions we’re asked most often about mobile app development. If you can’t find the answer you’re looking for, book a free consultation and we’ll figure it out together.
The cost of app development depends on the app’s complexity and the number of hours required. A simple app can take 40 hours, while an advanced app with integrations may require over 1,000 hours.
Simpler apps therefore start at around 40,000 SEK, while larger solutions often range from 200,000 to 500,000 SEK.
Book a meeting and we’ll provide you with a more accurate estimate based on your requirements.
The timeline depends on the app’s size and complexity. A simple MVP can be ready in 6 weeks with our MVP Sprint. A more advanced app with integrations typically takes 3–6 months. We always establish a clear timeline at the start of the project.
We do not charge any fees beyond the cost of developing the app.
However, there are additional costs for an Apple Developer account (USD 149/year) and a Google Play account (USD 25 one-time fee), which are your responsibility.
If the app is integrated with third-party services, additional licensing fees may apply.
Yes, we operate under a non-disclosure agreement (NDA) if the client so desires. We understand the importance of protecting confidential information, business ideas, and technical solutions throughout our collaboration.
We operate, maintain, and further develop your app after launch through our service agreement.
This means we handle bugs, security updates, and new features. We automatically monitor the app and are always available when something happens.
