# .NET Core vs DevPrep

The clearest difference is update cadence: DevPrep at every 2 days against .NET Core's every 18 months. .NET Core's advantage is iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. .NET Core sells 3 in-app purchases, starting at $19.99 per 7 days and DevPrep sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

.NET Core ships an update every 18 months, DevPrep every 2 days. The most recent releases landed on September 20, 2026 and October 10, 2026 respectively.
