# AVR Tutorial vs ClearNode

The clearest difference is in-app purchases: ClearNode at none against AVR Tutorial's 10. ClearNode also leads on review sentiment (100% vs 75%) and update cadence (every 2 weeks vs every 3 months). AVR Tutorial's advantage is rating (5.0 vs 4.8) and iOS requirement (9.0 vs 26.0). On price, ads and device support there is nothing between them.

Both are free to download. AVR Tutorial sells 10 one-off in-app purchases. ClearNode asks for nothing beyond the download.

AVR Tutorial holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: ClearNode has 32 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 75% of AVR Tutorial's written reviews are positive against 100% of ClearNode's, so the app with the better star average is not the one people write more warmly about.

AVR Tutorial ships an update every 3 months, ClearNode every 2 weeks. The most recent releases landed on September 24, 2026 and August 29, 2026 respectively.
