# Instaread vs SummaryZ

The clearest difference is monetization model: SummaryZ at free with in-app purchases against Instaread's subscription. SummaryZ also leads on review sentiment (56% vs 40%). Instaread's advantage is ratings volume (9.3K vs 109) and device support (3 vs 1). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Instaread sells 9 in-app purchases, starting at $2.99 per month and SummaryZ sells 4 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Instaread holds the better App Store score, 4.6 against 4.5. That said, the two scores are not equally well evidenced: Instaread has 9.3K ratings behind it against 109, so its average is the more settled of the two. Written reviews complicate that: 40% of Instaread's written reviews are positive against 56% of SummaryZ's, so the app with the better star average is not the one people write more warmly about.

Instaread ships an update every 2 months, SummaryZ monthly. Both last shipped on November 11, 2026.
