# WAUDOG Smart ID vs Світло

The clearest difference is rating: Світло at 4.6 against WAUDOG Smart ID's 3.5. Світло also leads on ratings volume (38 vs 6). WAUDOG Smart ID's advantage is review sentiment (71% vs 57%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. WAUDOG Smart ID sells 3 in-app purchases, starting at $19.99 per month and Світло sells 6 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Світло holds the better App Store score, 4.6 against 3.5. That said, the two scores are not equally well evidenced: Світло has 38 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 71% of WAUDOG Smart ID's written reviews are positive against 57% of Світло's, so the app with the better star average is not the one people write more warmly about.

WAUDOG Smart ID ships an update every 3 weeks, Світло fortnightly. Both last shipped on November 3, 2026.
