# Linux Basics vs K8s Guide

The clearest difference is rating: K8s Guide at 5.0 against Linux Basics's 4.5. K8s Guide also leads on update cadence (every 3 days vs every 2 months). Linux Basics's advantage is in-app purchases (none vs 3) and ratings volume (66 vs 4). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. K8s Guide sells 3 one-off in-app purchases. Linux Basics asks for nothing beyond the download.

K8s Guide holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Linux Basics has 66 ratings behind it against 4, so its average is the more settled of the two.

Linux Basics ships an update every 2 months, K8s Guide every 3 days. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
