# Interchange vs Summit Reader

The clearest difference is rating: Summit Reader at 4.8 against Interchange's 4.3. Summit Reader also leads on monetization model (free with in-app purchases vs subscription) and review sentiment (86% vs 73%). Interchange's advantage is ads (none vs shown) and update cadence (every 6 days vs every 3 weeks). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Interchange sells 9 in-app purchases, starting at $2.49 per month and Summit Reader sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Summit Reader holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Summit Reader has 1.3K ratings behind it against 212, so its average is the more settled of the two. Written reviews point the same way: 73% of Interchange's written reviews are positive against 86% of Summit Reader's.

Interchange ships an update every 6 days, Summit Reader every 3 weeks. The most recent releases landed on October 20, 2026 and October 21, 2026 respectively.
