# Study Buddy vs ISTQB Prep Exam CTFL v4.0

Study Buddy and ISTQB Prep Exam CTFL v4.0 are too close to call on the numbers: across 3 compared parameters — price, in-app purchases and iOS requirement among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Study Buddy sells 1 in-app purchase, starting at $1.99 per month and ISTQB Prep Exam CTFL v4.0 sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
