# AUM vs Tensor

The clearest difference is price: Tensor at $12.99 against AUM's $24.99. Tensor also leads on in-app purchases (none vs 4) and review sentiment (100% vs 82%). AUM's advantage is ratings volume (524 vs 5) and chart position (#41 vs unranked). On rating, update cadence, ads and device support there is nothing between them.

AUM costs $24.99 and Tensor $12.99 up front. AUM sells 4 one-off in-app purchases. Tensor asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for AUM against 4.8 for Tensor. That said, the two scores are not equally well evidenced: AUM has 524 ratings behind it against 5, so its average is the more settled of the two. Written reviews are what separate them: 82% of AUM's written reviews are positive against 100% of Tensor's.

AUM ships an update every 3 months, Tensor every 2 months. The most recent releases landed on October 18, 2026 and October 7, 2026 respectively.
