Choose 1Chess Clock if you want the repository-backed no-account, offline Android setup with Fischer, Bronstein, and several configurable clock settings. Choose Chrono Chess if the current Google Play listing's simple configurable timer, blitz/rapid/classical labels, move increment, color switching, offline wording, and no-ads/no-account wording match your needs. Neither source supports an absolute winner; the useful choice depends on which documented behavior matters at your board.
Quick answer: who should choose what
1Chess Clock is aimed at a two-player phone clock with a portrait layout, equal or unequal starting times, common presets, custom presets, pause, display options, sound, haptic feedback, and multiple delay types in the reviewed repository. The product plan also describes offline use and no account required. Chrono Chess's current listing describes clear touch controls, light and dark mode, configurable timers, move increment, color switching, blitz, rapid, and classical games, plus offline use and no ads or accounts.
If you need to understand a 3+2 or 10+5 setup before choosing an app, read the common time-control guide. If you want a neutral phone-at-the-board routine, use the phone setup guide.
Criteria and evidence
This table keeps product-source evidence separate from listing copy. It does not infer that an unlisted feature is absent.
| Criterion | 1Chess Clock repository and plan | Chrono Chess Google Play listing |
|---|---|---|
| Offline and account wording | The plan states offline use and no account required. | The listing states works offline and says no ads, no accounts. |
| Timer configuration | The source includes starting-time settings, equal or unequal times, presets, and custom presets. | The listing states configurable timer. |
| Time-control language | The source includes Fischer, Bronstein, simple delay, and other clock modes. | The listing states move increment and names blitz, rapid, and classical games. |
| Player-side behavior | The source uses two player clock panels and a hand-over tap. | The listing states clear touch controls and color switching. |
| Display scope | The Android source locks the app to portrait and includes display modes and themes. | The listing mentions light and dark mode; orientation is not stated in the feature copy reviewed. |
| Pause or interruption details | The source documents manual pause and pause on app interruption. | Pause behavior is not stated in the feature copy reviewed. |
Best for
Choose 1Chess Clock when its specific mode vocabulary, custom preset flow, portrait phone layout, or no-account/offline plan claims fit the game. Choose Chrono Chess when a compact feature list built around configurable timers, increment, color switching, named game speeds, offline use, and no accounts is the clearer match. A player who wants broad evidence across several Android listings can continue to the Best Android chess-clock comparison.
Who should not choose either on the listing alone
Do not choose solely from the word “offline” if the event has its own equipment rule, or if you need a specific delay model not named in the source. Do not assume that a listed game category is a tournament endorsement. Ask the organiser about the clock, run the agreed pre-game setup, and keep a backup plan for interruptions.
Limitations
This page compares the current 1Chess Clock repository and plan with the Chrono Chess listing checked on 2026-10-03. It does not test accuracy, touch response, sound, screen readability, battery behavior, or the current release UI. “Not stated” is deliberately left as an evidence gap rather than filled with a guess.
