Feature lists are useful only when they describe the version players can actually use. For 1Chess Clock, the current repository evidence supports a focused two-player clock, common time-control modes, presets or game settings, pause/reset behavior, and offline use without an account. Sound and other planned settings should be checked against the distributed build before they are advertised as available.
Start with the verified checklist
| Feature | What the evidence supports | What to confirm before publishing a claim |
|---|---|---|
| Two-player clock | Two large tap areas for switching turns | Whether the latest build changes the layout |
| Countdown | The active player loses time as the clock runs | The exact display behavior in the installed build |
| Fischer increment | Configured seconds are added after a completed move | The selected base time and increment in a test game |
| Bronstein delay | The configured grace period applies at the start of a turn | The mode and delay value in a test game |
| Presets | Built-in time-control presets and custom setup are documented | The labels shown in the current release |
| Pause and reset | Pause preserves the current session; reset returns to the chosen setup | The confirmation flow before a real game |
| Offline use | The clock can be prepared and run without internet; no account is required | Install or update the app before going offline |
The common time-control guide explains the numbers, while the offline guide describes the practical network check.
Time controls and game flow
The core product behavior is the clock, not a large collection of unrelated tools. Use a simple countdown when no extra time is agreed. Use Fischer when seconds are added after a completed move; the Fischer setup guide shows how to separate base time from increment. Use Bronstein when the agreement is a grace period at the start of each turn; the Bronstein guide covers that mode separately.
Before the game, check the two player panels and make one move from each side. This confirms both the touch routine and the time behavior. It is more reliable than inferring the mode from a preset name.
Settings that need release checking
The repository includes evidence for game settings, Fischer settings, and display settings. The feature plan also mentions haptic feedback and lists alert sound selection, themes, and a keep-screen-awake option in the settings roadmap. That roadmap is not by itself proof that every item is available in the public build. Do not promise a particular sound selector, theme, warning threshold, or screen-awake toggle until the shipped version has been checked.
The same rule applies to future controls such as Canadian overtime, byo-yomi, multi-stage controls, or Armageddon presets. A feature can be a useful idea without being a current product claim.
Choose features for the game
For a normal over-the-board game, prioritize a readable two-player display, the correct time mode, and a predictable tap after each move. For an offline session, install and test the app first, then leave the settings alone when play begins. If a club or event requires a feature that is not confirmed, ask the organiser or use equipment whose behavior is already accepted rather than filling the gap with an assumption.
