Verdict
The clearest difference is monetization model: PocketBook Reader at free with in-app purchases against Interchange's subscription. PocketBook Reader also leads on ratings volume (9.8K vs 212) and rating (4.5 vs 4.3). Interchange's advantage is update cadence (every 6 days vs every 2 months) and review sentiment (73% vs 54%). On price, ads, in-app purchases and device support 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. PocketBook Reader sells 41 one-off in-app purchases and Interchange sells 9 in-app purchases, starting at $2.49 per month. Whichever you choose, the download price is not the number that matters.
PocketBook Reader holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: PocketBook Reader has 9.8K ratings behind it against 212, so its average is the more settled of the two. Written reviews complicate that: 54% of PocketBook Reader's written reviews are positive against 73% of Interchange's, so the app with the better star average is not the one people write more warmly about.
PocketBook Reader ships an update every 2 months, Interchange every 6 days. The most recent releases landed on September 27, 2026 and September 25, 2026 respectively.
