Discovery: Laying the foundation for your mobile app
The journey to a successful mobile app starts here. Our discovery phase is designed to uncover your vision, refine your ideas, and set the stage for development. Here’s how we do it:
Requirement analysis: We're eager to know as much as possible about your expectations and app vision: target audience, use cases, features, long-term goals, timelines, and budget. The more we know, the faster we can kick off development.
Got open questions? Our experts are ready to guide you with professional advice and industry best practices.
Market research: We can help you better understand competitors in your niche — what features their apps offer, what hooks their target audience — and suggest a differentiation strategy.
Feature elicitation: Our specialists define your app's essential features and create simple mockups and wireframes to visualize its look and feel.
Feasibility analysis: Right from the start, we assess whether your project can be delivered as planned — on time, within budget, and with the features you want. If any challenges arise, we’ll identify them early and work with you to adjust the plan for success.
Strategic planning: Setting the stage for well-oiled development
You want your mobile app development journey to be smooth and predictable. So do we. That’s why we thoroughly plan every step, leaving no detail to chance.
Mobile app shaping: We turn everything uncovered during the discovery phase into an SRS (software requirements specification). By prioritizing features for your MVP (minimum viable product), we help you balance essential functionality and your time-to-market goals.
Our experts recommend a mobile platform and technology stack and design the app architecture.
Project roadmap: With the big picture in place, we craft a detailed project plan that breaks everything down into actionable steps. This roadmap includes:
- Milestones to track progress
- Timelines to stay on schedule
- Resource and role allocation
- Detailed cost estimates are to be kept within your budget.
Design: Crafting the look and feel of your app
Great UI/UX design captivates users — often within seconds. That’s why we focus on creating intuitive designs that win hearts at first glance.
Prototyping: Prototyping offers a sneak peek into your app’s functionality and flow, helping refine complex projects before committing to a full-scale design. For small-scale apps or when iterative development is planned, we can skip prototyping to save time while maintaining quality.
UI/UX: We map out user journeys to uncover how they’ll navigate your app, what excites them, and where potential friction points might arise. The result? An intuitive, seamless experience free from bottlenecks and hurdles — designed to bring delight with every tap, swipe, and scroll.
User testing: Real users, real insights. We invite representatives of your target audience to walk through specific scenarios in your app. This critical step helps us pinpoint design flaws and refine every element, ensuring your app feels as smooth and natural as it looks.
Development: Building the face and brain of your app
We bring your app to life with attention to detail, staying aligned with your vision and focused on delivering excellence.
Frontend: We build responsive, visually captivating interfaces that adapt seamlessly across devices. Lightweight designs, smooth animations, and fast-loading screens ensure a flawless user experience, optimized for battery efficiency and one-handed comfort.
Backend: We build secure servers, robust databases, and the logic that drives your app’s features, ensuring seamless, lightning-fast data flow and reliability at every step.
Testing: Ensuring quality that wows the world
Quality is everything, so we offer comprehensive mobile testing services to leave no aspect untested and no detail unchecked.
Functionality testing: From functionality and usability to performance and compatibility, our QA team ensures your app delivers on every promise — no glitches, no surprises.
Usability testing: We test app navigation, design, and flow to ensure users can achieve their goals without frustration.
Performance testing: Our QA team ensures your app can handle the pressure — be it heavy traffic, spotty connectivity, or demanding usage scenarios.
Compatibility testing: We test your app across a range of phones, tablets, and OS versions to make sure it shines everywhere.
Launch and publishing: Going live
Your app is polished and ready for the big stage. Here’s what happens next:
Preparation for submission: We set up your Apple or Google developer account and ensure your app meets all App Store or Google Play Store guidelines.
App publishing: From crafting a compelling app page with all the essential details and engaging visuals to uploading your app, submitting it for review, and finally hitting publish — we handle it all so you can focus on celebrating your launch.

Our work — in our clients’ words
As a leading custom app development company, we've mastered the art of mobile development — and our clients' glowing reviews say it all.
Chris Yamamoto
Founder, guide:human
“Vention is developing a mobile and web application for Apple devices. The mobile app is iOS native, and the web app has been built using React.js.
Vention cares about our project and their performance is great. After a bad experience with a previous development agency, I didn’t trust other companies and wanted to work with two partners in case something went wrong again. Vention has changed my mind and earned my trust. Our relationship has grown over time, and they’re my only development partner now.”
David Dawson
CTO, Mast Mobile
“All of our clients have been a big fan of the app. Vention did an excellent job of building what we needed, and I liked the way they structured it. They delivered everything on time and within budget.”
Sarah Miller
CEO, Bundle Birth
“Vention has been developing an iOS and Android mobile app for us. This app is being built specifically for labor and delivery nurses. Vention is very invested in the project, which has had a positive impact on the quality of their work. They actually care and understand what they're doing rather than just checking the boxes. Said understanding has been reflected in the quality of their work and their investment in our success.”
Lee Tupper
CTO, Remotiv
“We initially hired Vention to design and develop a new mobile application and that evolved into an ongoing full-stack relationship. We were very happy with the initial specification, the design prototypes and the accuracy of time estimates on the sprints.”
Rami Abrams
Co-Founder, Tasteaholics, Inc.
“We wanted to rebuild and expand our existing Android app to be on both iOS and Android and add a huge number of features. The new app was a huge success and had optimized performance speed and quality compared to the original Android app (even though that one was fully native). We're very happy with the team and final results of the app (we had ongoing development for 3 years).”
Christopher Vroom
Founder, CollectorIQ, Inc.
“The team developed our iOS app, using a wrapper for the Android app because we wanted to have a single code base.
The application Vention architected is very robust and complicated, and they’ve done a great job. They’ve enabled us to scale in a very positive way. The fact that we’ve been able to build incrementally on this solid foundation has been a cornerstone of our company’s success.”
Jun Seki
CTO, Healthera
“We have successfully launched the integration projects and product features to increase conversion rate and captured wider markets.
Not only they were highly skilled professionals in their own domain, but also they have good communication skills. We learnt from each other on technical knowledge and also on project/ product management side. They were very engaging and proactively listening for feedbacks and improve ways of working.”
Joe O'Connell
VP of Product, Seed-stage startup
“They were very autonomous. We’re a small team, with not a lot of managerial resources, but they were able to pace themselves. They required very few check-ins to stay on pace. They’ve been able to roll with us as we go and adapt to what we needed as a startup.”
Matt Sunbulli
CEO, Networking company
“Vention has a strong supply of grade A talent across numerous disciplines, which is important when you need to move quickly. They have high expectations for their employees, who deliver on time and are always professional. The individual developers are accountable and invested in our success — they want to please the client, which is unique these days.”
Christopher Osborn
CTO, Voxy
“Our mobile application lagged behind or didn't include the features of our web application. This team has created parity and in cases been ahead of our web development since taking over the projects.”

Every business is unique, and so are the challenges it faces. Whether you're looking for complete development support or just an extra boost for your team, we offer an engagement model tailored for you.
When to choose outsourcing?
You need end-to-end mobile app development with minimal involvement. Outsourcing is ideal if you prefer focusing on your core business while leaving the heavy lifting to a third party.
As your trusted outsourcing partner, we'll handle daily workflows, manage the team, monitor budget adherence and deadlines, and plan and deliver your mobile app.
You’ll stay in control with regular syncs with our project manager and clear milestone and KPI reports.
When to choose a dedicated team?
You have no in-house experts to execute your app vision and hiring isn’t part of the long-term plan. A dedicated team is a perfect scenario as it gives you full control over development workflows.
Engage the team of Ventioneers — proven professionals who have delivered dozens of mobile projects. The team typically includes roles like a mobile developer, a UI/UX designer, a QA specialist, and a DevOps engineer, but it can be adjusted or scaled to match your specific business needs.
When to choose staff augmentation?
You’ve got the necessary talent and streamlined workflows, but what you need is an extra edge — and fast. Whether adding developers to accelerate delivery or bringing in AI and blockchain experts to close skills gaps, staff augmentation gets you there without delay.
With Vention, you’ll find the right fit every time. Our 3,000+ professionals are top-tier domain experts and specialists in cutting-edge technologies, ready to hit the ground running and deliver results.
Hear from our expert
"Three main challenges of mobile development — expertly solved.
Got an app idea? We know how to approach it. Here’s how we tackle the toughest challenges in mobile software development:
Transforming your idea into a feasible plan
App success hinges on detailed requirements, clear objectives, and realistic timelines and budget estimates. Our discovery and strategic planning services provide all these, ensuring your idea is set up for success.
Building an integrated ecosystem
Delivering an app that works seamlessly across devices, operating systems, and screen sizes is no small feat.
Our work starts with architecture design and extends to a wide range of tasks like API creation, cross-platform development (if it’s a part of the plan), user-centric design, and regular testing.
Balancing feature-richness
Packaging an app with dozens of fancy features is tempting, but that can slow development, hurt performance, and overwhelm users. Through target audience analysis, user journey design, and feature prioritization, we identify what brings the maximum value to you."
