Verdict
The clearest difference is ads: Cosmo at none against hellolive's shown. Cosmo also leads on ratings volume (283 vs 52). hellolive's advantage is review sentiment (86% vs 59%) and rating (4.0 vs 3.8). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. hellolive sells 8 one-off in-app purchases and Cosmo sells 10 in-app purchases, starting at $8.69 per month. Whichever you choose, the download price is not the number that matters.
hellolive holds the better App Store score, 4.0 against 3.8. That said, the two scores are not equally well evidenced: Cosmo has 283 ratings behind it against 52, so its average is the more settled of the two. Written reviews point the same way: 86% of hellolive's written reviews are positive against 59% of Cosmo's.
hellolive ships an update every 9 days, Cosmo every 8 days. Both last shipped on November 7, 2026.
