MarkFlow's advantage is in-app purchases (none vs 3) and update cadence (daily vs every 8 days). On review sentiment, ads and device support there is nothing between them.

Comet is free to download; MarkFlow costs $0.99 up front. Comet sells 3 in-app purchases, starting at $20.00 per month. MarkFlow asks for nothing beyond the download.

Comet holds the better App Store score, 4.7 against 3.7.
