# Acrobots vs Vortis

The clearest difference is price: Vortis at Free against Acrobots's $0.99. Vortis also leads on rating (5.0 vs 4.4) and update cadence (every 5 days vs every 5 weeks). Acrobots's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.

Vortis is free to download; Acrobots costs $0.99 up front. Vortis sells 1 one-off in-app purchase. Acrobots asks for nothing beyond the download.

Vortis holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Acrobots has 25 ratings behind it against 1, so its average is the more settled of the two.

Acrobots ships an update every 5 weeks, Vortis every 5 days. The most recent releases landed on November 6, 2026 and October 31, 2026 respectively.
