A free explorer of the whole App Store: apps, full review text, rankings and the merchants who wrote the reviews.
Free
Watch for. No company or person is named anywhere on the site, and it has no terms of use, no privacy policy and no pricing page. It hands out merchant contact emails it found by itself, so anyone writing to them should check the consent rules first. It keeps reviews that Shopify took down. It is free, and nothing on the site says how it pays for itself.
The whole App Store as a live database, free on the web and over MCP.
Free, Pro $49/mo
Listed here because: same category.
Details for one of these are not confirmed yet, so no difference from HeyApps is stated.
Watch for. Store records come from public App Store reviews. A store only appears if it has publicly reviewed an app. It is not install data, and they say so plainly.
