App Testing

Deliver Flawless App Experiences
In a world where 88% of mobile time is spent in apps, quality is everything. Just two bugs can lead to uninstalls, and a few bad reviews can hurt conversions. Trinity Dev combines manual and automated testing to catch every issue before users do. With 2,500+ hours of annual testing across iOS, Android, and cross-platform apps, we ensure smooth launches and top ratings.What you get: ✔ Zero critical bugs at launch✔ 4.5+ app store ratings ✔ 30–50% lower post-launch costs ✔ Full compliance with Apple & Google standards

The high cost of poor app quality

01

Financial consequences:

Fixing bugs after launch costs 6-15x more than before launch (IBM Systems Sciences Institute) Each star in a rating reduces conversions by 5-9% (Apptentive) Mobile app data breaches cost an average of $4.24M per incident (IBM Security)

02

Changes in user behavior:

62% of users won’t give a second chance after a bad experience (Deloitte) 85% of uninstalls are due to performance issues (AppsFlyer) 90% of negative reviews cite stability issues (Apptweak)

03

Disadvantages of competition:

47% of users compare competitor apps (ThinkWithGoogle) App stores demote apps with ratings below 4 stars

04

Performance Optimization for Speed ​​and SEO

Google favors fast-loading websites, and 40% of users abandon a page if it takes longer than 3 seconds to load. A slow website negatively impacts conversions, revenue, and SEO rankings. Our performance testing includes: Load Testing: We simulate 10,000+ concurrent users to assess stability. Stress Testing: We determine system limits. Resource Optimization: We minimize the impact of large files, inefficient scripts, and server latency.

05

Cost Effectiveness and Risk Reduction

Fixing bugs after your site goes live can be 5 times more expensive than fixing them during development. A single undetected bug can lead to: Lost sales (e.g., broken payment process). Negative reviews that destroy trust. Expensive emergency fixes that drain resources. Our proactive testing saves you time, money, and stress by catching problems early.
