ASO tools FAQ

What are the best free ASO tools?

The list is not ranked. It is grouped by task. The two ActivationPal tools are free with the limits shown. Apple custom product pages and Google Play store listing experiments are built into the stores. In the sources checked, Astro lists no free tier and AppTweak lists a free trial.

Which ASO tools work for Google Play?

Google Play store listing experiments and Google Play acquisition reporting, both in Google Play Console. The keyword checker is App Store only.

How does the keyword checker score popularity and difficulty?

Popularity is how few letters you type before the exact keyword appears in App Store search suggestions. The earlier it appears, the higher the score. Difficulty grows with the total ratings of the top 10 results, falls with the number of those with fewer than 50 ratings, and grows with how many of the top 25 contain the keyword in the name or subtitle. Both run from 0 to 10. Once the listing converts, set store prices per country with the country pricing tiers.
