7.1: the leaderboard gets a Weekly board! • New "This Week" leaderboard, refreshed every Monday (UTC) — even if you can't top the all-time board, you can still claim first place this week • New All-Time / This Week toggle on the leaderboard; your all-time best scores are preserved forever • Submitting a score now clearly tells you whether you set a new global best or a new weekly best • Apple Watch can also submit to the weekly board • Various leaderboard stability and detail improvements Every Monday your weekly ranking starts fresh — come back and race for this week's crown!

7.0 is a major update — the Apple Watch app gets a full overhaul. Apple Watch • Multi-core computation • Submit your results to the global leaderboard and compete with users worldwide • Digit limit raised from 1 million to 10 million • A post-calculation prompt shows your result and lets you submit with one tap • New time estimation and a smoother, more accurate progress bar • Fixed truncated results on small-screen models (Multi-core, leaderboard, and 10M digits are Pro features) iPhone, iPad & Mac • Deep computation engine optimization — large-digit calculations up to about 2× faster • New Apple Watch device category filter on the leaderboard • Delete your leaderboard records per device If you submitted scores to the global leaderboard before 7.0, we recommend recalculating and resubmitting — after this engine optimization your times will be noticeably shorter, improving your ranking. Plus various stability fixes and refinements.

UI refinements

- Full iOS 26 Liquid Glass redesign: floating tab bar, glass sheets and headers across all tabs - More accurate calculation time estimates with per-magnitude calibration - App now available in 14 languages — Traditional Chinese, Japanese, Korean, German, French, Spanish, Portuguese, Italian, Dutch, Russian, Arabic and Greek added
