# VBMAPP vs TallyFlex

The clearest difference is rating: TallyFlex at 4.3 against VBMAPP's 3.7. TallyFlex also leads on update cadence (every 2 weeks vs monthly) and review sentiment (64% vs 53%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. VBMAPP sells 10 one-off in-app purchases and TallyFlex sells 2 in-app purchases, starting at $27.99 per month. Whichever you choose, the download price is not the number that matters.
