# Thunder Pro vs Invoice Mama

The clearest difference is rating: Invoice Mama at 5.0 against Thunder Pro's 3.6. Invoice Mama also leads on review sentiment (100% vs 71%). Thunder Pro's advantage is ads (none vs shown) and ratings volume (48 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Thunder Pro sells 8 in-app purchases, starting at $9.99 per month and Invoice Mama sells 2 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.
