# AVR Tutorial vs Capacitor

The clearest difference is in-app purchases: Capacitor at none against AVR Tutorial's 10. Capacitor also leads on review sentiment (100% vs 75%) and ratings volume (10 vs 2). AVR Tutorial's advantage is update cadence (every 3 months vs every 40 months) and rating (5.0 vs 4.8). 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. Capacitor 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: Capacitor has 10 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 Capacitor'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, Capacitor every 40 months. The most recent releases landed on October 5, 2026 and September 9, 2026 respectively.
