# VIVOSUN vs LYKYN

The clearest difference is rating: VIVOSUN at 4.7 against LYKYN's 4.2. VIVOSUN also leads on ratings volume (8.7K vs 25) and update cadence (fortnightly vs monthly). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

VIVOSUN holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: VIVOSUN has 8.7K ratings behind it against 25, so its average is the more settled of the two. Written reviews complicate that: 62% of VIVOSUN's written reviews are positive against 67% of LYKYN's, so the app with the better star average is not the one people write more warmly about.

VIVOSUN ships an update fortnightly, LYKYN monthly. The most recent releases landed on November 10, 2026 and November 5, 2026 respectively.
