Verdict

The call

The clearest difference is in-app purchases: The Doctor's Time Machine at none against Ellipse's 3. The Doctor's Time Machine also leads on rating (5.0 vs 4.7) and iOS requirement (12.0 vs 15.0). Ellipse's advantage is ads (none vs shown) and ratings volume (2K vs 2). On price and device support there is nothing between them.
