Verdict

The call

The clearest difference is review sentiment: Libra reader at 100% against Sutra's 73%. Sutra's advantage is rating (4.3 vs 4.0) and ratings volume (18 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Sutra sells 4 one-off in-app purchases and Libra reader sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Sutra holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Sutra has 18 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 73% of Sutra's written reviews are positive against 100% of Libra reader's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sutra ships an update every 8 days, Libra reader fortnightly. The most recent releases landed on November 10, 2026 and November 13, 2026 respectively.
