FAQ
What will I receive?
You will receive a comprehensive PDF report containing detailed explanations, annotated screenshots of all issues and video recordings of the trickier ones, along with actionable advice on how to further enhance your product.
Do you work alone or in a team?
I work with a small team of highly qualified professionals, which is another great advantage for you. This means you'll benefit from multiple perspectives and expertise, ensuring thorough testing of your product from every angle.
What type of bugs will you find?
We'll find not only functional bugs but also UI, UX & usability issues, typos, text/copy issues, font problems, performance issues, and more. Our thorough testing covers all aspects to ensure top-notch quality for your product.
My product isn't live yet. Is it possible for you to test while still in development?
No problem! For iOS apps I will need access to the app in TestFlight. For Android apps I will need the .APK file of the app you want tested. Please message me before placing an order so that we can discuss all the access details before the timer starts. Thank you!
I have a website. Can you test it?
Yes, we also do website testing. Check out my other gigs, or just send me a message to receive a custom offer.

Ongoing collaborationKristin's work on this project was above average for a QA engagement of this scope. The platform is meaningfully better as a result of her two testing rounds and the issues she surfaced were real, well-documented, and directly actionable. She will be the preferred choice for future QA work on this project as it grows.
