Tired of juggling apps, websites, and bookmarks to plan your race training? CalcuRun is an all-in-one solution — completely free, with no ads and no accounts. Newly redesigned in version 3.0 with a chronograph-inspired look and a dot-matrix display, CalcuRun helps you predict race times, plan splits, and dial in your workout paces. Features * Input a recent race or time trial and get accurate predictions across common race distances. * Use the "Other" race distance for non-standard events. * View splits for each race, in kilometers or miles. * Get workout paces based on your predictions. * Use the Calculator to plan an individual race — input a time or pace and calculate the other. * Sync your saved races and predictions across your iPhone and iPad with iCloud. * Redesigned iPad layout with a sidebar that takes advantage of the bigger screen. * Choose between the new dot-matrix display font or the system monospaced face. * Learn more about how the calculations are performed. Most importantly, your data is private. Calculations run entirely on your device. CalcuRun does not require an account, internet access, or any device permissions. iCloud sync is fully encrypted, and your data is never sent to a CalcuRun server. If you choose to follow any in-app links, only the URL is passed to your default browser.
