Verdict
The clearest difference is monetization model: Coach Sidekick at free against Assignr's subscription. Coach Sidekick also leads on update cadence (every 11 days vs every 6 weeks). Assignr's advantage is ratings volume (8.3K vs 1). On price, rating, ads and in-app purchases there is nothing between them.
