# Booster Prep vs NIHCertification

Booster Prep and NIHCertification 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. Booster Prep sells 7 one-off in-app purchases and NIHCertification sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Booster Prep ships an update fortnightly, NIHCertification every 2 weeks. The most recent releases landed on September 26, 2026 and September 15, 2026 respectively.
