# KPApp vs SERU Mock Test

The clearest difference is update cadence: KPApp at every 4 days against SERU Mock Test's every 6 weeks. SERU Mock Test's advantage is review sentiment (100% vs 75%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. KPApp sells 1 one-off in-app purchase and SERU Mock Test sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

KPApp ships an update every 4 days, SERU Mock Test every 6 weeks. The most recent releases landed on September 8, 2026 and June 1, 2026 respectively.
