# Sheiko vs Strength System Online

The clearest difference is rating: Sheiko at 4.3 against Strength System Online's 2.0. Sheiko also leads on ratings volume (20 vs 4). Strength System Online's advantage is in-app purchases (none vs 3) and update cadence (every 2 weeks vs every 5 weeks). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Sheiko sells 3 in-app purchases, starting at $12.99 per 3 months. Strength System Online asks for nothing beyond the download.

Sheiko holds the better App Store score, 4.3 against 2.0. That said, the two scores are not equally well evidenced: Sheiko has 20 ratings behind it against 4, so its average is the more settled of the two.

Sheiko ships an update every 5 weeks, Strength System Online every 2 weeks. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
