# Amortization Calculator vs Compounder

The clearest difference is review sentiment: Compounder at 100% against Amortization Calculator's 33%. Compounder also leads on iOS requirement (13.0 vs 15.0). Amortization Calculator's advantage is ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Amortization Calculator sells 2 in-app purchases, starting at $12.99 per year and Compounder sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
