Verdict

The call

The clearest difference is in-app purchases: SpaceReality at none against Heliosphere's 3. SpaceReality also leads on iOS requirement (12.0 vs 18.0). Heliosphere's advantage is update cadence (every 3 days vs every 10 months). On price, ads and device support there is nothing between them.
