# Formulize vs Promo Buddy

The clearest difference is rating: Promo Buddy at 5.0 against Formulize's 4.5. Promo Buddy also leads on monetization model (ad-supported vs free with in-app purchases). Formulize's advantage is ads (none vs shown). On price, ratings volume, in-app purchases and device support there is nothing between them.

Both are free to download. Formulize sells 1 one-off in-app purchase and Promo Buddy sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Promo Buddy holds the better App Store score, 5.0 against 4.5. Both are backed by a comparable volume of ratings — 2 and 1 respectively.
