Verdict
The clearest difference is in-app purchases: Rhythm · Advanced Studies at none against Solar Walk 2's 7. Rhythm · Advanced Studies also leads on update cadence (fortnightly vs every 2 months). Solar Walk 2's advantage is price ($2.99 vs $6.99) and device support (4 vs 2). On ads there is nothing between them.
