Verdict

The call

The clearest difference is price: Interchange at Free against Epub繁简通's $12.99. Interchange also leads on ratings volume (212 vs 1) and update cadence (every 6 days vs fortnightly). Epub繁简通's advantage is rating (5.0 vs 4.3) and in-app purchases (none vs 10). On review sentiment, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Epub繁简通 holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Interchange has 212 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 73% of Interchange's written reviews are positive against 71% of Epub繁简通's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Interchange ships an update every 6 days, Epub繁简通 fortnightly. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
