Verdict
The clearest difference is review sentiment: Lingo7 at 100% against FBReader's 52%. Lingo7 also leads on rating (4.8 vs 3.7) and update cadence (every 2 days vs monthly). FBReader's advantage is ratings volume (128 vs 6) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. FBReader sells 1 one-off in-app purchase and Lingo7 sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Lingo7 holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: FBReader has 128 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 52% of FBReader's written reviews are positive against 100% of Lingo7's.
FBReader ships an update monthly, Lingo7 every 2 days. The most recent releases landed on October 13, 2026 and October 2, 2026 respectively.
