The next chapter
of Terminal Drill.

Four tracks. One learning history.

Terminal Foundations, Developer Workflows, Linux Operations and RHCSA preparation organise the library around your goals. Shared content keeps one identity and progress history.

Practical work that remembers your changes.

66 labs cover the RHCSA chapters, six capstones and twelve broader exercises. Inspect a represented machine, edit its files, run supported commands and submit the resulting state. Save a checkpoint and come back later. Labs include declared limits and pending independent-review labels.

Classic stays. Adventure joins it.

Classic remains the default. Adventure adds missions, a character profile, twelve achievements, earned titles and cosmetics, flexible weekly goals, rematches and six homelab keepsakes. Switch in Settings; progress, XP and purchases are shared.

More trustworthy progress.

Visible answers, hints and independent recall are treated differently. Lab participation rewards cannot become certification claims. Repeating the same completed lab variant does not repeatedly award XP.

Your data, under your control.

Manual backup and replacement restore include compatible progress, preferences and lab checkpoints. Purchase ownership continues to come from Apple. No accounts, ads or app analytics were added.

Built for iPhone, iPad and Mac.

The update adds a Mac Catalyst app, a larger workspace, improved practice presentation and fixes for Mac navigation. Platform availability follows each App Store review.

The purchase promise.

One-time Full Access includes every track and future content updates. Previously free content remains free, including Starter Ops, with a useful RHCSA sampler added. There is no separate expansion SKU.
