# OmNom Notes vs TachyMon

The clearest difference is ratings volume: TachyMon at 286 against OmNom Notes's 4. OmNom Notes's advantage is update cadence (every 3 weeks vs every 3 months) and rating (4.0 vs 3.8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. OmNom Notes sells 1 one-off in-app purchase and TachyMon sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
