    Doesn’t let me log in — I’ve been trying to sign in, I’ve even got to changing my email and resetting my password multiple times and nothing. And in order to submit a ticket I have to sign in first which I can’t

    The “All-In One” cold plunge is a Lemon — Purchased 18 months ago. Constant mechanical issues with my All-In one. Zero customer support (impossible to reach a human at company to discuss). Terrible customer support and a lemon product

    Abysmal quality — Do not buy Plunge. I own the Plunge Pod with the Evolve Pro Chiller, and it’s had two critical failures: the chiller previously went into an error state for no reason and needed a full replacement, and now the clear filter housing canister has cracked on its own — a manufacturing defect that risks leaking the entire tub since it sits right in the water line. Plunge doesn’t even s

    Bad app — The app totally sucks. One day I go to Steam, I'm forced to log in to my account using a password and a username, I enter all my data, and as it turns out, the password is incorrect, although I saved it and wrote it down in notes. I contacted support, they asked for the mail to which the code should come. As a result, nothing came, I clicked on the account search. I think they found it,

Apps count as part of a market for 90 days after they last appear in it. Installs are Google Play's own count, last captured 2026-09-13. 3 of 8 apps have an Android listing we could match. A dash means we could not pair the two stores, not that the app is absent from Play. Amber marks an app that has not shipped in over 90 days, the 90th percentile across every market we hold.

How this is counted

Every number is arithmetic over the reviews we hold, re-counted weekly: nothing modelled, nothing scored. Themes come from a frozen pattern classifier rather than a model reading reviews, so the same review always lands in the same bucket. A market rate is pooled across every app here; the store rate is the same count across 12,743 apps. A complaint is only called a gap when at least half the market carries it, at least 20 reviews are behind it, and the market’s rate is elevated above the store’s, the same cutoff used everywhere on this site, because a problem concentrated in one app is that app’s bug, and a problem every app on the store shares is nobody’s gap. This market has no full report yet, so the per-app notes are absent rather than estimated. The anger axis is counted either way: mean star of the reviews carrying each theme, from the same classifier as the counts above.
