# Protech DNA vs SGS

The clearest difference is rating: SGS at 5.0 against Protech DNA's 2.6. SGS also leads on ads (none vs shown) and monetization model (free vs ad-supported). Protech DNA's advantage is ratings volume (5 vs 1) and iOS requirement (13.4 vs 17.0). On price, update cadence, in-app purchases and device support there is nothing between them.

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

SGS holds the better App Store score, 5.0 against 2.6. That said, the two scores are not equally well evidenced: Protech DNA has 5 ratings behind it against 1, so its average is the more settled of the two.

Protech DNA ships an update every 2 months, SGS every 5 weeks. The most recent releases landed on October 2, 2026 and October 16, 2026 respectively.
