# GCP vs Data Engineer Exam Prep

GCP and Data Engineer Exam Prep are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases 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. GCP sells 2 one-off in-app purchases and Data Engineer Exam Prep sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

GCP ships an update fortnightly, Data Engineer Exam Prep every 10 days. Both last shipped on November 13, 2026.
