# Vibration analysis vs Toolbox

The clearest difference is rating: Toolbox at 4.5 against Vibration analysis's 4.0. Toolbox also leads on ratings volume (14K vs 43) and update cadence (every 2 weeks vs every 3 months). Vibration analysis's advantage is ads (none vs shown). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Vibration analysis sells 2 one-off in-app purchases and Toolbox sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Toolbox holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Toolbox has 14K ratings behind it against 43, so its average is the more settled of the two. Written reviews point the same way: 57% of Vibration analysis's written reviews are positive against 63% of Toolbox's.

Vibration analysis ships an update every 3 months, Toolbox every 2 weeks. The most recent releases landed on October 4, 2026 and October 15, 2026 respectively.
