# Stochastic Signal Processing vs TokenMax

The clearest difference is update cadence: TokenMax at weekly against Stochastic Signal Processing's every 5 weeks. TokenMax also leads on rating (5.0 vs 4.7). Stochastic Signal Processing's advantage is ratings volume (6 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

TokenMax holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Stochastic Signal Processing has 6 ratings behind it against 1, so its average is the more settled of the two.

Stochastic Signal Processing ships an update every 5 weeks, TokenMax weekly. The most recent releases landed on September 25, 2026 and October 1, 2026 respectively.
