The Unseen Challenges Web Teams Face When Building Mobile Apps
Most organizations do not recognize the complexity involved in mobile app development and think that since they can develop websites, they can develop apps. This is a false assumption that comes at a high price, as mobile development brings unfamiliar issues that web teams do not expect. Common review challenges are:
1. Metadata Requirements
The rules of the App Store of Apple and Google Play are strict and constantly changing. New mobile teams are prone to rejection cycles, which can take weeks to launch. Some common challenges are:
2. Guidelines Materials
Promotion materials, descriptions, and images of apps must be formatted accurately. Any discrepancy or deviation in guidelines leads to rejection.
3. Privacy Policies
The two stores need elaborate privacy disclosures and tracking records. Lack or unclear statements are instantly discarded.
Review Timelines
- Apple: 1-7 days
- Google Play: Instant to a few weeks
One rejection will restart the process, resulting in significant delays.
4. Guideline Interpretation
The policies tend to be vague. Experienced mobile teams understand the way in which reviewers actually interpret rules and how to not enter into rejection loops.
Platform-Specific Design Requirements
The expectations of the iOS and Android app designs are fundamentally different. This is something that web teams do not always consider, and so the apps are sensed to be off or unpolished. Major Design Differences:
1. Navigation Patterns
- iOS: lower-bottom tabs, swipe
- Android: menu of hamburgers, Material Design framework
These patterns ought to be ignored, as it makes the app look unnatural.
2. Typography & Spacing
There is a system of each platform:
- iOS: San Francisco
- Android: Roboto
Spacing scales differ too. A web design that appears alright on the web will appear unprofessional on the mobile.
3. Interaction Feedback
iOS and Android differ in haptic feedback, animation curve, and transition styles. It is the instant feeling in the user when something feels wrong.
The teams without mobile design experience usually design web apps in native wrappers, which are perceived by users as of low quality.
Device Fragmentation & Testing Complexity
Compared to the small number of browsers used in web development, mobile has to be tested in a gigantic ecosystem. Testing challenges include:
1. Device Configurations
Different:
- Screen sizes
- Pixel densities
- Hardware capabilities
2. Performance Variations
Your app must work on:
- High-end flagship devices
- Low-end phones with low RAM.
3. OS Version Fragmentation
- Particularly in Android, where 5+ OS versions are typical.
4. Mobile-Specific Edge Cases
Web teams rarely consider:
- Interruptions (notifications, calls)
- Background/foreground state processing
- Battery usage
- Memory constraints
Such problems have devastating impacts on the performance of apps.

Release Management Orchestration
There is no way to deploy mobile apps in the simplest manner compared to updating a site.
Mobile release challenges:
1. Multi-Platform Coordination
iOS and Android releases are to be coordinated, whereas iOS reviews cause instability.
2. Staged Rollouts
Best practice:
5% – 25% – 50% – 100%
This identifies invisible problems at an early stage.
3. Rollback Limitations
Web rollbacks are instant. Mobile rollbacks require:
- New build
- New submission
- User update
4. Version Compatibility
Your backend should be able to support multiple versions of your apps since users do not update immediately.
5. Emergency Hotfixes
Bugs of issues of a critical nature demand immediate review requests; they might or might not be approved within a short time at Apple.
Those teams that do not practice mobile release usually attempt to use web workflows that do not happen in mobile settings.
What Is the Ideal Team Size for a Mobile App Development Project?
The number of team members would be determined by the complexity of the project:
- Small App (Basic MVP): 5 to 7 team members
- Medium App (Booking, Social Apps, Ecommerce): 8 to 12 team members
- Enterprise, Healthcare, Fintech (Large-Scale App): 12 to 20 team members
With the complexity of your project, a properly organized mobile app development team expands.
“A great mobile app development team doesn’t just write code, it engineers experiences, anticipates user needs, and turns business vision into digital reality.”
– Muzamil Liaqat Rao, CEO at 8ration
Understanding App Development Costs
Businesses always fall under the cost priority. The cost of mobile app development depends on:
- App complexity
- Platform (iOS, Android, or both)
- Technology stack
- Where your development team is based
- The level of developers’ seniority.
- Integrations (AI, GPS, payments, streaming, IoT, and so on)
To make your estimation easier, we will divide the common app developer salary scales and team cost structures.
