# FretTools vs Guitar Visualizer

The clearest difference is monetization model: FretTools at freemium against Guitar Visualizer's subscription. FretTools also leads on rating (5.0 vs 4.7) and update cadence (every 6 days vs every 3 weeks). Guitar Visualizer's advantage is ratings volume (44 vs 8) and device support (3 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. FretTools sells 3 in-app purchases, starting at $2.99 per month and Guitar Visualizer sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

FretTools holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Guitar Visualizer has 44 ratings behind it against 8, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

FretTools ships an update every 6 days, Guitar Visualizer every 3 weeks. The most recent releases landed on October 31, 2026 and November 7, 2026 respectively.
