Verdict
The clearest difference is in-app purchases: Block Line Up at none against SynthStack's 1. Block Line Up also leads on ads (none vs shown) and iOS requirement (12.0 vs 15.6). SynthStack's advantage is update cadence (every 2 days vs every 14 months). On price and device support there is nothing between them.
