Building an iOS app is only half the journey — ensuring it performs seamlessly across different iPhones, iOS versions, and real-world scenarios is what determines its success.
Now comes the critical decision: Should you handle testing in-house or hire a professional iOS app testing team?
Many teams begin by testing internally. Some rely on developers to test their own code. While this can be enough during MVP or prototype stages, it often leads to missed bugs, poor reviews, or even App Store rejection once the app is live.
In this blog, we’ll break down the pros and cons of DIY iOS QA versus professional testing services, so you can decide what’s right for your product.
🤔 What Does DIY iOS App Testing Actually Mean?
DIY stands for Do It Yourself. In the context of QA, it refers to internal, self-managed testing — often without a formal testing process or a dedicated QA team.
This might involve:
- Founders or product managers testing basic flows
- Developers reviewing their own code in a simulator
- Skipping structured test cases or real-device testing
- Relying on visual checks rather than functional deep dives
At first glance, this may seem like a time-saving option. However, it typically results in:
- Bugs that only appear on real devices going unnoticed
- Uncaught UX issues that impact user retention
- App Store rejection due to compliance or stability problems
✅ When DIY Testing Might Be Acceptable
There are a few limited cases where basic in-house QA can work:
- Early MVPs built for internal demos
- Single-platform apps with minimal features
- Wireframe/prototype testing for investor pitches
- Temporary use before hiring a QA partner
Even then, it’s essential to document findings and retest thoroughly.
That said, once your app is heading to production, you’ll need deeper, structured QA to avoid launch risks.
🚨 Why DIY QA Isn’t Enough for App Store-Ready Products
Let’s look at what often goes wrong with self-managed QA:
❌ Limited Device Coverage
Most internal teams test only on the latest iPhone model, ignoring other iOS versions, screen sizes, or network conditions.
❌ No Real-User Simulation
In-house testing often skips user behaviors like denying permissions, receiving a call mid-session, or using Face ID with poor lighting.
❌ App Store Rejection Risks
Apps that crash, have missing error messages, or fail IAP sandbox checks are frequently rejected by Apple.
❌ Missed UX Flaws
Tiny tap zones, broken gestures, or inconsistent layouts pass undetected until users leave 1-star reviews.
