Verdict
The clearest difference is monetization model: TeamSideline at free against Assignr's subscription. TeamSideline also leads on update cadence (weekly vs every 6 weeks) and chart position (#174 vs unranked). Assignr's advantage is review sentiment (73% vs 41%) and rating (4.9 vs 4.6). On price, ads, in-app purchases and device support there is nothing between them.
