# Oi vs Video Summarizer

The clearest difference is ads: Oi at none against Video Summarizer's shown. Video Summarizer's advantage is rating (4.7 vs 4.3) and ratings volume (158 vs 20). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Oi sells 4 in-app purchases, starting at $7.99 per 7 days and Video Summarizer sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Video Summarizer holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Video Summarizer has 158 ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 80% of Oi's written reviews are positive against 75% of Video Summarizer's, so the app with the better star average is not the one people write more warmly about.

Oi ships an update monthly, Video Summarizer every 3 weeks. The most recent releases landed on October 6, 2026 and October 23, 2026 respectively.
