The clearest difference is in-app purchases: Guerrillazen at none against Postureletics's 10. Guerrillazen also leads on rating (5.0 vs 4.6) and device support (4 vs 1). Postureletics's advantage is update cadence (every 10 days vs every 2 months) and ratings volume (253 vs 17). On price, ads and iOS requirement there is nothing between them.

Both are free to download. Postureletics sells 10 in-app purchases, starting at $9.99 per month. Guerrillazen asks for nothing beyond the download.

Guerrillazen holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Postureletics has 253 ratings behind it against 17, so its average is the more settled of the two.
