How this is scored

Weighted mean of the sub-scores, weights re-normalized over whatever is computable (nobody's fixed it 25 · how far above typical 20 · how angry 15 · people in the market 15 · room to enter 15 · willingness to pay 10). Fixed anchors map each count to 0–100: breadth and willingness-to-pay are straight shares; the gap’s heat tops out at 4times the store’s typical rate; anger scores star3 as 0 and star1.5 as 100; reach runs 104 to 107ratings on a log scale; room to enter is one minus the leader’s share of shelf ratings. A factor that cannot be counted is dropped and named — never imputed. The site’s one composite (#115, owner decision 2026-08-15); cited industry benchmarks are never blended in.

“TERRIBLE — This is babyish! If you are 11 or 12 years old did you know you can create an account under 13 on TikTok, also why do you have to pay??? The CEO is trash. Go to TikTok now!”Zigazoo · 1star · Aug 16, 2026
“I LOVE COVERSTAR!!! — I love Coverstar so much but the prom is with it only the verified people get to do anything and you have to pay for premium so like you only get to make one minute long videos and the verify people get to do everything And all you get stuck with is doing one minute one videos if you don’t have premium”Coverstar - Positive Social · 3star · Aug 15, 2026
“I’m disappointed about this — First of all every time I try to sign in it asks me about a Google website and then takes me to make an account when I’m trying to sign in, now I may have to restart my whole account when I’ve just reached 300 followers. I’m clicking the correct buttons and it’s just not working, I’ve recommended Coverstar many times and many times people have downloaded it but I thin”Coverstar - Positive Social · 2star · Aug 15, 2026

“😡 — No this app is not the best for me if u wanna be popular on this app u have to get premium and that is eight dollars a month and it's really anoyinggg when u don't have it u only have thirty seconds to do ur videos and u don't get like any views u get like three in a week and no comments or subs and like two likes and a shorter bio if u don't have premium, I don't have premium an all those thi”Zigazoo · 1star · Aug 15, 2026
“Idk — Don’t get me wrong, it’s a really good app but it is really glitchy and is kind of unfair to the un-verified community. The people who aren’t verified would like to put stories too you know! The passes are pretty pricey so I wouldn’t recommend. Maybe the premium is pretty nice but going live whenever should be included but u get why you get chosen to see if you can get in. There would be too”Coverstar - Positive Social · 3star · Aug 15, 2026
“Ummm — It is not letting me like put my username in it’s just putting a little X next to it so I think this app is useless”Zigazoo · 1star · Aug 12, 2026

“Coverstars — I hate it why can only the verify people do all the fun stuff? Like there are small creators and they can not go live they can’t post stories like just put a limit on people for going live this in not okay”Coverstar - Positive Social · 1star · Aug 13, 2026
“I don’t trust it — This app works, and is actually somewhat helpful, but I have a hard time trusting it. First off, it relies heavily on generative ai which is already a red flag, but it also requires full access to your account. In theory it could start uploading things to your account without you even knowing. Also, way too much is behind a paywall. It’s so stupid just how much stuff I can’t use”vidIQ for YouTube & Instagram · 3star · Aug 1, 2026
“why I don’t recommend some poor families — you lost a star because you’re trying to make it more like TikTok as a Therian I want to post all about me, like not all about myself just a few fun facts, but for some reason, it’s limiting me and I know there’s some kids out there like me and their subscription so much you need to pay chess for 60 second videos and timers I think Coverstar is a lot bett”Zigazoo · 2star · Jul 23, 2026

“So much money — It's a fine app, but to do stuff you need to pay 💰. Without Zigazoo Premium, you basically have nothing. Also, there's only few who get popular and there is mild hate 🤬”Zigazoo · 1star · Aug 20, 2026
“Just an extra app taking up space — I was trying to use buffer for a social Media fast but still post content. Paid for the monthly subscription for 3 channels and as soon as I deleted the OG apps, I started having problems! I’m just one person with one phone posting to multiple apps, how is the teams feature? I know it has to be doo doo because I’m having issues with just me!

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 shelf rate is pooled across every app here; the store rate is the same count across 12,122 apps. A complaint is only called a gap when at least half the shelf carries it and at least 20 reviews are behind it — a problem concentrated in one app is that app’s bug.
