Briefly, what should you know?
Realistic mobile app schedule includes not only coding time; includes discovery, design approvals, content, testing and store review.
Who is this guide for?
- Startups that turn a mobile product idea into an MVP
- Teams choosing iOS, Android or cross-platform
- Decision makers who prepare the budget and publication schedule
- Businesses that manage store processes for the first time
We prepared this guide based on Codeexia's project experience, official sources and real questions that are repeated in bid negotiations. It states the variable fees and technical conditions with its sources; We do not present project estimates as a final offer.
How long does it actually take to get a mobile app made? Despite the widely spoken statement in the market that "we will finish it in 3 months", the real times are; Ranges from 6 weeks to 12 months depending on scope, platform, team capacity and store approval processes. Wrong expectation is the biggest cause of project delay: if the schedule is underestimated, the team will appear behind in every sprint, whereas the problem lies in the time estimation.
In this article, we examine all the phases an application goes through from idea to store publication, realistic durations of each phase, estimation ranges that vary depending on the number of screens and features, and common causes of delay. Finally, we present a template you can use to plan your calendar.
7 phases of a mobile app
- Discovery and brief (1-3 weeks): Defining business purpose, target audience, competitor analysis, MVP scope and success metrics.
- UX and prototype (2-4 weeks): User flow, information architecture, wireframe and prototype.
- UI design (2-4 weeks): Design system, screen designs, micro-interactions, delivery files.
- Backend and API development (3-12 weeks): Database, authentication, business logic, integrations.
- Mobile development (4-20 weeks): Native or cross-platform code, UI implementation, API connections.
- QA and testing (2-4 weeks): Manual testing, automatic testing, device matrix, security tests.
- Store release (1-3 weeks): App Store and Google Play review, fixes, release.
Some of these phases can be executed in parallel. For example, backend and mobile development start in parallel; However, starting mobile development before UX approval is completed often creates revision costs.
Realistic times depending on application complexity
| Application type | Number of screens | Total time | Notes |
|---|---|---|---|
| Simple MVP / catalog application | 8-15 | 6-10 weeks | Single platform, limited backend, ready-made UI kit |
| Midrange business app | 15-30 | 3-5 months | Login, profile, notification, payment |
| E-commerce / ordering application | 25-45 | 4-7 months | Cart, payment, shipping, notification, campaign |
| SaaS platform | 40+ | 6-10 months | Multiple roles, comprehensive reporting |
| Marketplace / two-sided platform | 50+ | 8-12 months | Two different user types, payment flows, trust layers |
Effect of platform selection on time
Native (Swift + Kotlin) approach usually takes 40–60% longer than cross-platform (Flutter, React Native) approach. An application within the same scope:
- Cross-platform: 4 months
- Native iOS + Android parallel: 5.5–6.5 months
- Hybrid (some modules are native): 5 months

Common reasons for delays
Delay in application projects is generally not due to code writing speed; It is caused by external factors.
- Content delay: The most common reason is that content such as text, images, and product data are delayed by the customer.
- Late design approvals: When the decisions that need to be made at the Wireframe stage are left to the UI stage, a double revision occurs.
- Indefinite scope: “Let's add this” requests constantly expand the MVP.
- Late starting QA: Leaving QA to the end creates an accumulation of errors.
- Store rejection: Decisions that do not follow Apple's Review Guidelines may result in rejection on release day.
- Integration surprises: Third party service with no or inconsistent API documentation.
- Key person change: Departure of a critical person from the team or by the client.
Store approval times
- Google Play: Standard applications 1–3 days; For new accounts it may take 1-2 weeks.
- Apple App Store: Average 1–3 days; In projects where rejection is not inevitable, 5-7 days should be planned for a 1-time revision + resubmission scenario.
- Age/content rating and privacy: Additional disclosures are required per Apple's App Privacy and App Tracking Transparency policies.
How does the MVP approach affect time?
MVP is the smallest set of features that produce the core value of the application. Instead of releasing all features in the first version, the delivery time is shortened by 40–60% in projects planned as phase 1 MVP + phase 2 growth + phase 3 maturation. This approach has three big advantages:
- Fast entry to market — critical in competing projects with competitor concerns
- Real user data — accurately prioritizing subsequent sprints
- Risk mitigation — don't redo the wrong feature

Sample calendar: Mid-range business app
| Week | activity |
|---|---|
| 1-2 | Discovery, brief, success metrics |
| 3-5 | User flow, wireframe, prototype |
| 6-8 | UI design system and screens |
| 5-12 | Backend and API (starts in parallel) |
| 8-16 | mobile development |
| 15-18 | QA, device matrix, security testing |
| 18-20 | Store publication preparation and review |
In this example, the total duration is approximately 4.5-5 months. Adding content, approval and third party service delays, 5.5-6 months is a realistic expectation.
Practical advice
Before asking the agency about the deadline, plan the preparations on your own front: content, brand assets, payment provider selection, privacy policy, store account opening. Even if these preparations are not considered to be on the critical path, they determine 20-30% of the project.
5 ways to shorten the time
- Minimize MVP; Leave features to phase 2.
- Prepare the content before the project starts.
- Choose a cross-platform framework.
- Have store accounts and privacy policy ready before development is finished.
- Run QA in parallel from the beginning.
Frequently asked questions
How long does it take for an average mobile application to be published?
3-5 months is a realistic time for an average business application. Simple MVPs can take 6-10 weeks, complex SaaS applications can take 8-12 months.
How long does App Store and Google Play approval take?
Google Play generally reviews in 1-3 days, App Store in 1-7 days.
How much does going live with MVP shorten the time?
The MVP approach can reduce delivery time by 40-60%.
Why doesn't the time estimate come true?
Because scope changes, late approvals, and content delays create the real forecast deviations.
