The clearest difference is in-app purchases: Space/Time at none against Timeshifter's 3. Space/Time also leads on rating (5.0 vs 4.7) and update cadence (daily vs weekly). Timeshifter's advantage is ratings volume (2.7K vs 1) and chart position (#32 vs unranked). On price, ads and device support there is nothing between them.
