# Chronogram vs marks

The clearest difference is rating: Chronogram at 5.0 against marks's 4.6. Chronogram also leads on review sentiment (100% vs 88%). marks's advantage is update cadence (every 3 days vs every 2 weeks) and ratings volume (91 vs 17).

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
