Verdict
The clearest difference is in-app purchases: Inner Space at none against SunSync's 2. Inner Space also leads on device support (3 vs 1) and iOS requirement (14.0 vs 17.6). SunSync's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 7 months). On price there is nothing between them.
