Use this table to decide whether a workflow fits your task. Product version, device support and active plan can change what is available.
| Capability | What the product documents | Boundary to check |
|---|---|---|
| Practice modes | Tactics, positional exercises, endgames and Guess the Elo are described publicly. | A puzzle score is not equivalent to an official tournament rating. |
| Engine feedback | On-device analysis supports offline study. | Engine evaluations depend on position and search conditions; they do not guarantee future playing strength. |
| Access | The public offering includes free play and optional training access. | Check current daily limits and entitlements in the installed version. |
Keep the source material until you have checked the result. A supported format or visible option does not guarantee that every input will work identically. Test the smallest example that includes the property you care about: text, timing, a formula, a recurring event, metadata or a language pair.
Consult the current app and storefront for local prices, taxes, renewals and entitlements. These guides do not make a fixed regional price or lifetime-availability promise. Product-specific free/paid distinctions are recorded above only where the public materials describe them.
