Hi Product Hunt, I'm Jared, and I am the solo developer of OneStar.

Most tools for pulling and analyzing app reviews rely on expensive methods, so they're priced for ongoing monitoring of your own apps. That makes it hard to just look something up: check a competitor before you build, size up a market, or dig into one bad week after a release. I wanted that kind of quick, ad hoc analysis to be cheap enough to run whenever a question comes up.

OneStar does both jobs.

Research a market

Report on any app or game on the App Store, Google Play or Steam: what people love, why they leave, what they ask for. Free.
Compare up to four apps on the same questions to see where a competitor is weak.

Listen to your own users

Connect App Store Connect and OneStar reads every review in every country, checks new ones daily, and shows what to fix first and what changed after a release.
See which 1 and 2 star reviews are still waiting on a reply, and get an alert when complaints spike, so you answer upset users while it still matters.

The screenshots contain a real comparison: Hinge vs Bumble vs Tinder, 8,898 reviews. 90% of Bumble reviewers complain, led by pricing and paywall. Bumble's developers replied to 22% of those reviews, Tinder's to under 1%. Every number opens the reviews behind it: Public Report

Under the hood, Jev (TypeSafe's model) asks every review the same 12 questions and answers with a confidence. Code does the counting, and unsure answers stay visible.

Free is 3 reports a month, up to 500 reviews each, no card. Pro is $19 a month and adds comparisons and your own app. PH folks get 30% off Pro with code PRODUCTHUNT.

Reply with any app or game, yours or a competitor's, and I'll run it and post the report here.
