Common questions

About the free app rating calculator.

Get in touch
Is it free?
Yes. The rating calculator is completely free — no sign-up, no credit card, no limits. Calculate as many scenarios as you want.
How does the calculation work?
The calculator uses the standard App Store rating algorithm. It takes your current rating, the number of existing ratings, your target rating, and the average star rating of new reviews, then calculates the exact number of reviews needed to reach your goal.
Does it work for Google Play?
Yes. The calculator supports both App Store and Google Play rating algorithms. You can compare how many reviews you'd need on each platform to reach the same target rating.
Can I calculate the impact of negative reviews?
Yes. You can see how a batch of negative reviews would affect your overall score. Model 1-star, 2-star, or any mix of reviews to understand the impact on your rating before it happens.
How accurate is it?
The calculator is highly accurate — it uses the official App Store and Google Play rating formulas. However, it doesn't account for factors like review filtering, weighted averaging, or regional differences.
How is this different from AppTriage?
The rating calculator is a free planning tool to model your rating changes. AppTriage is a full review management platform that tracks your actual rating in real-time, auto-imports new reviews, and helps you improve your score by managing feedback.
