Tournament & Kiosk Reliability
Built-in Auto-Save on interruption, hold-to-confirm protection against accidental pause/reset, inactivity dimming to save battery, and wake-lock protection.
How Is Chess Clock Financed?
Chess Clock is built with passion as an independent project. Instead of locking players into costly monthly subscriptions, the app relies on a fair, transparent 3-way model:
1. Free to Play & Free Video Passes
All core time controls, duels, and the Funzone are free. If you want real player names, avatars & custom colors without paying, simply unlock the Custom Pass via short rewarded videos:
- ✓1 video = +6 hrs • 2 videos = +12 hrs • 3 videos = +24 hrs (stackable up to 72 hrs)
- ✓Tournament Ritual: Before a long classical game, watch 1 short clip to play the entire match 100% ad-free!
- ✓If no ad inventory is available (No-Fill), the app automatically gifts you the time pass anyway.
2. Chess Clock PRO for a One-Time €3.59
For less than the price of two coffees, you permanently unlock the full PRO version on your device — with zero recurring fees:
- ★100% ad-free — permanently removes all banners and video prompts
- ★Pro Layout with professional keypad (name, ELO/DWZ, title, flag, club) & up to 25 saved player profiles
- ★Full Pro Customizing (Imperial Gold, Silver, Steampunk, etc.), Outdoor Light Mode & FIDE Arbiter Mode
3. Offline Sponsorship, Event Banners & Customizing
Because chess clocks are frequently used in airplane mode at tournaments (or when users try to bypass ads by going offline), Chess Clock features a built-in Offline Sponsorship system:
- •Rotating Offline Partner Banners: Sponsor banners are bundled directly inside the app/APK and rotate reliably whenever the device is offline (100% ad-blocker proof!)
- •Dedicated Event & Club Banner in the Pro Layout (custom logo, tournament title, round info & link) plus custom club color branding
- •Bulk Activations (offline PINs or custom-branded APK builds) for schools, youth academies, tournaments, and entire chess clubs
Miles Ahead: What's Coming Next
Chess Clock is continuously evolving. Look forward to these upcoming highlights and expansions in future updates:

Configure once, transfer onto any number of club tablets: complete export & import system for all 25 player profiles (including cropped avatars), custom presets, duel templates, and archives.
Asian Modes: Byo-yomi for Go & Shogi
