About Our Reviews
How are apps selected for review?
We review apps through several channels: user requests, developer submissions, trending apps in stores, and editorial picks based on our analysis of market needs and user interests.
How long does a review take?
Each app undergoes 1-2 weeks of testing before review publication. This includes installation, initial assessment, in-depth testing, extended real-world usage, and editorial review.
Do you accept payment for reviews?
Absolutely not. We maintain complete editorial independence. Our reviews are never influenced by advertising, sponsorships, or developer payments. All apps are evaluated using the same objective criteria.
Can I request a review of a specific app?
Yes! Send your suggestions to [email protected]. While we can’t guarantee we’ll review every suggested app, we carefully consider all requests.
How often do you update reviews?
We monitor apps for major updates and re-review when significant changes occur. Popular apps are re-evaluated at least annually to ensure our reviews remain current and accurate.
Ratings & Scores
What’s the difference between Expert Score and User Score?
The Expert Score is calculated by our professional reviewers using standardized testing criteria. The User Score aggregates ratings from our community members who have actually used the app. Both provide valuable perspectives.
How is the Expert Score calculated?
Our expert score uses a weighted formula based on five criteria: Functionality (25%), User Experience (25%), Performance (20%), Security & Privacy (15%), and Value (15%). See our Rating Methodology page for details.
Why might Expert and User scores differ?
Differences can occur for various reasons. Expert reviews focus on technical quality and design, while users may prioritize different aspects. Both perspectives are valuable in understanding an app’s overall quality.
What does a score of 8.5 really mean?
Scores of 8.0-8.9 indicate excellent apps with high quality and minimal flaws. We use a 10-point scale where 9-10 is outstanding, 8-8.9 is excellent, 7-7.9 is good, and 6-6.9 is above average.
For App Developers
How do I submit my app for review?
Email your submission to [email protected] with your app store links, description, and any relevant materials. See our For Developers page for detailed submission guidelines.
How long until my app is reviewed?
The review process typically takes 2-4 weeks from submission to publication, depending on app complexity and our review queue. We’ll acknowledge your submission within 2 business days.
Can I respond to my app’s review?
Yes, developers can post official responses to reviews and engage with user comments. Contact us after your review is published to set up developer access.
What if I disagree with my app’s rating?
We stand behind our reviews, but we’re open to feedback. If you believe factual errors were made or important features were overlooked, contact us at [email protected] with specific details.
Can you review my app faster for a fee?
No. We do not offer expedited reviews or any paid services that would compromise our editorial independence. All apps are reviewed in queue order using the same process.
Privacy & Security
Do you collect personal information?
We collect minimal information needed to operate the site, such as analytics data and user ratings. We never sell personal information. See our Privacy Policy for complete details.
How do you evaluate app security and privacy?
We review each app’s requested permissions, privacy policy, data collection practices, and security measures. Apps with concerning privacy or security practices receive lower ratings and clear warnings in reviews.
Are user ratings verified?
We use multiple techniques to identify and filter suspicious ratings, including pattern analysis and user verification. While no system is perfect, we work hard to ensure rating authenticity.
Technical Questions
Which platforms do you cover?
We review apps for both iOS (iPhone and iPad) and Android platforms. Our reviews specify which platforms were tested and whether the experience differs between them.
Do you test on different devices?
Yes. We test apps on multiple devices including latest flagship models, mid-range devices, and various OS versions to ensure our reviews reflect real-world performance across different hardware.
How do you test app performance?
We use a combination of specialized tools and real-world usage to evaluate load times, responsiveness, battery consumption, memory usage, and stability across different scenarios and network conditions.
