Understanding the mobile app startup landscape

Before entering any market, you should be aware of what to expect. Figures mentioned at the beginning of the article indicate that the mobile app market is growing. Here are some other statistics and facts that startup founders, executive teams, CEOs, CTOs, and project managers should take into consideration.

Climbing data

The global mobile app revenue is rising, as more and more people are using mobile apps and the market is growing. Therefore, app downloads increase, as well as the general quantity of apps in Google Play and App Store. Startup app development teams should consider cross-platform app development services to attract more potential customers.

User interests

Smartphones are deeply integrated in people’s daily digital behavior, as in the US, users spend about 70% of their digital media time on mobile apps. The same report indicates that millennials use apps for finding information mostly, while zoomers are first of all interested in communicating with family and friends. The domains with the most mobile apps and the highest numbers of startups in 2025 are gaming, business, social media, and e-commerce sectors. For example, users spend on average 202 minutes per month on mobile shopping apps. Mobile-friendliness of apps is extremely important nowadays, as 40% of customers abandon a purchase if they don’t like the site or app UI and UX.

Current trends

AI has brought its impact on mobile app development for startups and enterprises. Gartner predicts that AI assistants will dominate the digital environment in 2027. Therefore, partnering with technical experts who are not just coders but who keep tabs on the latest trends, such as AI and ML.

The adoption of AR and VR is another tendency that is especially relevant in the gaming domain. Such apps need native development for top-level performance, so startups might require Android and iOS app development services.

Superapps that bundle multiple services pose another trend. They target younger users, raised in the smartphone era, who seek mobile-focused platforms that are both robust and user-friendly.

Challenges of the market

In the question ‘How to start an app business’, CEOs should think first of all not about the technological side, but about the hurdles of the market. Fierce competition, overcrowded market domains, cross-platform compatibility, time-to-market pressures, and ever-evolving privacy/security demands are the obstacles every startup should know about and be prepared to struggle with. Solutions include powerful and cost-efficient development tools and frameworks, cutting-edge functionality, detailed customer profiles, and partnerships with a reliable mobile app development company.

How to choose a reliable partner

Partnering with a technological company means a startup doesn’t have to worry about hiring developers and selecting relevant tools and frameworks. Technical expertise and experience of a company in certain business domains are important criteria. Besides that, a partner should also understand the business goals and the general strategy of the startup. Here are some questions that a startup CEO can ask a potential partner during a due diligence process:

  • What is your experience with projects similar to ours?
  • What technologies do you specialize in, and how do you evaluate new tech?
  • How is quality assurance managed?
  • What are your security and compliance protocols?
  • What happens post-launch?

While discussing those questions, you will see if a software development firm aligns with your objectives and matches technical requirements. Specify the methodologies (Agile, Scrum) and regularity channels (Slack, Jira) for smooth communication. Explore their architectural approach and their capacity to support long-term growth, including regular updates and technology maintenance. Finally, ask about price tariffs, timeline, and post-launch costs.

Startup mobile app development may also happen in-house. It gives businesses full control of the process, minimizes risks of sensitive data leaks, and promotes close team integration. On the other hand, recruiting competent experts is time-consuming and pricey. Building an effective team and processes from scratch usually takes longer than delegating to an experienced external agency.

How to start an app

PixelPlex IT experts consulted us on the general steps of the startup mobile app development process. It usually includes the following stages:

1. Planning

Make a list of your app ideas. Decide on the pain of your customers that you are going to cover. Translate your business objectives to technical requirements. Choose the core functionality to check it on the MVP and receive the first feedback. Set measurable goals and KPIs to assess the success of your app. Conduct the market research and think of the reasons why some startups succeeded and others failed.

2. Choosing a platform

Continue the research regarding what type of devices your potential customers use. Define whether your app will be for Android, iOS, or both. You may analyze the number of downloads, market share, and projected revenue to make a decision. Cross-platform development makes your app universal for different devices. However, it may limit AR/VR and other advanced technological possibilities.

3. Designing an excellent UI/UX

Users’ attention span has decreased. You only have several seconds to interest a potential customer with your app. That’s why the interface should be user-friendly and intuitive. You should prioritize features with business impact in mind. For example, use the feature bucket categorization to classify features into categories like “must-haves,” “nice-to-haves,” and “delighters” based on the business impact and effort required.

4. Agile development

Agile methodologies provide startups with rapid iteration and adaptation. It ensures regular assessments of the milestones, feedback cycles, and transparent reporting. Therefore, it is easier to spot the flaw and fix it without the necessity to restart from scratch. It also allows for staying within the time frames and budget. The MVP development focuses on “must-haves” and allows for faster time-to-market.

5. Raising funds

The question that any startup has to answer is how to raise money. Pre-seed funding, bootstrapping, and crowdfunding are possible options.

  • Choose pre-seed funding if you need significant funds upfront to build your product quickly, access mentorship, and networks. Pre-seed rounds often involve angel investors, friends and family, or early-stage accelerators.
  • Choose bootstrapping if you prefer to retain full control of your startup, want to prove your business model with minimal external pressure, or your startup does not require heavy initial capital investment. Bootstrapping relies on personal savings and early revenues.
  • Choose crowdfunding platforms (Kickstarter, Indiegogo) if your product or idea has a strong appeal to a broad audience and you want to raise capital while creating early customer engagement and validation. It’s often suitable at the very early stages or to generate buzz, but it requires effective marketing and community-building efforts.

6. Marketing

A relevant marketing strategy is key to transforming an unknown local brand into one with global awareness. Here are the main types of marketing for a mobile app startup:

  • App store optimization (ASO): Improve your app visibility with high-quality screenshots, keywords in the descriptions, and engaging titles.
  • Paid campaigns: Drive traffic through social media platforms and search engines.
  • Original equipment manufacturer (OEM) marketing: Partner with manufacturers to install your app on their devices or promote it while setting up the equipment.
  • Social media platforms: Find influencers with wide audiences who agree to try your app and review its functionality.
  • Retention campaigns: Retaining existing customers is no less important than acquiring new ones. Re-engage your audience with emails, push notifications, and personalized promotions.
  • Affiliate marketing: Attract partners who can promote your app to their networks in exchange for remuneration.
  • Traditional advertising: Billboards, road signs, TV commercials, and printed ads are still effective. They serve as additional touch points for your audience.

7. Monetization

Choose the way you wish to make money from your app. For example, in-app purchases allow users to buy extra features. With subscriptions, your customers can access the content or services for a certain period of time. The pay-per-download model brings you revenue when a user downloads the app. Each option comes with benefits and challenges, so it’s important to pick one that fits your app’s purpose and keeps users happy.

8. Maintenance & retention

Launching your app is just the beginning of the journey. To stay successful, you must regularly improve the app by releasing updates, fixing bugs, and adding new features based on user feedback. Keeping the app fresh and valuable encourages users to stick around and helps maintain a steady flow of downloads and revenue. Continuous updates also show that you care about your users and are committed to providing a great experience. Planning for ongoing maintenance and improvements is key to long-term success.

Clubhouse emerged in 2020, focusing on audio-only social networking. Founders Paul Davison and Rohan Seth iterated quickly in the audio space to build a format supporting live, drop-in voice conversations. Clubhouse rapidly went viral during the pandemic, with backing from top investors like Andreessen Horowitz and a $100 million+ valuation. It reached over 15 million installs in its first year.

The secret of success: The desire to join an exclusive community. It is possible to become a member of the clubhouse only through a special invitation that not everyone can receive.

How much does it cost?

Without discussing a project, it is impossible to say how much it will cost. However, it is useful to know how the price is formed and which functionality influences the budget.

App complexity Description Estimated cost range (2025) Typical features & details Development timeframe
Simple apps Basic apps with minimal features such as calculators or informational apps. Usually standard UI with no or minimal backend. $30,000 – $100,000 Basic functionality, simple UIs, possibly static content, minimal or no backend integration. These apps are quick to build and require fewer development hours. 2–4 months
Medium complexity Apps with more interactive features such as social media integration, payment options, user accounts, and basic APIs. $100,000 – $250,000 Multiple screens, custom UI elements, user login, database connections, third-party services (e.g., payment gateways or social APIs). Moderate backend and frontend work required. 4–9 months
Complex apps Feature-rich applications including custom animations, real-time updates, advanced security, multiple API connections, AI/ML, e-commerce platforms. $250,000 – $500,000 or more Sophisticated architecture, real-time/interactive features, AI or machine learning integration, extensive backend operations, high security, possibly ongoing maintenance and scaling. 9 months to 1 year or longer

Important notes:

  • Costs may be higher depending on the location of developers (e.g., US rates are much higher than India or Eastern Europe).
  • AI or ML features can increase costs by up to 300%, depending on complexity.
  • Maintenance, updates, and support after launch add to the total cost and timeframe.
  • The longer the project is, the more expensive it is, as it requires additional development hours.
  • Starting with an MVP reduces upfront costs and time, because engineers focus only on the core features.

Mobile app development challenges

Startup mobile app development is risky. However, if you adequately assess the risks and know how to address them, you will have higher chances for success.

Fierce competition

Get ready to compete by conducting careful market research. Define your direct and indirect competitors in the app space. Think of the unique features of your app that make it stand out. Tools like App Annie or Sensor Tower provide valuable competitor insights and app market trends, enabling you to learn from rivals and adapt quickly.

Limited budget

Calculate your realistic budget for app development, testing, launch, and maintenance. Select essential functionality for the MVP and those features that can wait, to save the budget. Leverage low-code/no-code platforms (FlutterFlow, Bravo Studio) or cross-platform frameworks (React Native, Flutter) to reduce costs.

Security issues

Learn what user data your app will collect, and how it will protect it. Make sure your mobile app complies with security and privacy regulations (e.g., GDPR, HIPAA) and ensures authentication, data encryption, and safe API integrations. Plan regular audits and vulnerability testing loops.

Skill gap

Analyze the team and decide whether you have the in-house technical expertise to build the app, or you should seek an expert development partner. You might miss some key technical skills or specialties that you can outsource. Examine the available frameworks and platforms that simplify the technical complexity.
