Service Overview

Protecting Your Brand Reputation

A single devastating bug that deletes user data or causes a payment failure can destroy an app's reputation permanently. At Hastree, Quality Assurance is not an afterthought; it is woven into the very fabric of our deployment pipeline.

We utilize a hybrid approach combining extensive automated script testing with rigorous manual human interaction. We test across massive physical device farms to guarantee your app looks and behaves perfectly whether it's running on a flagship iPhone 15 Pro Max or a 4-year-old budget Android tablet. We test for load, security vulnerabilities, battery drain, and edge-case network failures.

Frequently Asked Questions

Everything you need to know about our mobile engineering process.

Developers operate with an inherent 'happy path' bias-they test the app the way it's supposed to be used. Dedicated QA engineers are trained to use the app exactly how it's NOT supposed to be used, discovering the critical edge cases.
Mobile app development cost depends on complexity, platform choice, backend requirements, and third-party integrations. A well-scoped MVP can typically be delivered for $5,000-$30,000. More advanced products with complex backend systems, AI features, or enterprise-grade security requirements range higher.
A well-scoped MVP can typically be delivered in 4 to 8 weeks. More complex mobile platforms with advanced backend integrations, AI features, or stringent security requirements can take 2-6 months depending on scope.
Absolutely. We manage the entire deployment process, ensuring your application strictly adheres to Apple's Human Interface Guidelines and Google Play's Developer Policies, handling the submission, review, and final release.
