# TheosU vs DeepSpace

The clearest difference is price: TheosU at Free against DeepSpace's $0.99. TheosU also leads on ratings volume (82 vs 1) and iOS requirement (15.0 vs 26.0). DeepSpace's advantage is in-app purchases (none vs 5) and update cadence (every 5 days vs monthly). On ads and device support there is nothing between them.

TheosU is free to download; DeepSpace costs $0.99 up front. TheosU sells 5 in-app purchases, starting at $13.99 per month. DeepSpace asks for nothing beyond the download.

DeepSpace holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: TheosU has 82 ratings behind it against 1, so its average is the more settled of the two.

TheosU ships an update monthly, DeepSpace every 5 days. The most recent releases landed on October 16, 2026 and October 11, 2026 respectively.
