Verdict

The call

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.
