Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
ETC Library holds the better App Store score, 3.8 against 1.5. Both are backed by a comparable volume of ratings — 12 and 4 respectively. Written reviews complicate that: 25% of iGobo's written reviews are positive against 0% of ETC Library's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on October 16, 2026 and October 3, 2026 respectively.
