Verdict
The clearest difference is ads: Cognizer at none against Slidem's shown. Cognizer also leads on monetization model (free vs free with in-app purchases). Slidem's advantage is update cadence (every 3 weeks vs every 6 months) and rating (4.6 vs 4.4). On price, in-app purchases and device support there is nothing between them.
