Verdict
The clearest difference is in-app purchases: Ascent at none against Saturn's 1. Ascent also leads on ads (none vs shown) and ratings volume (16 vs 1). Saturn's advantage is rating (5.0 vs 4.6) and update cadence (every 10 months vs every 46 months). On price and device support there is nothing between them.
