Verdict
The clearest difference is price: con.sol.la at Free against SyndtSphere's $1.99. con.sol.la also leads on update cadence (every 5 weeks vs every 23 months) and iOS requirement (11.0 vs 13.0). SyndtSphere's advantage is in-app purchases (none vs 3). On ads and device support there is nothing between them.
