Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
A whole new look. RNDS 1.3 is cleaner, faster to read and easier to get around.
• Redesigned app: four simple tabs (Home, Social, Camp, You), clear numbers, calmer screens.
• Rhythm mode, front and center: a random beep tells you when to attack, like an opening in a fight.
• Try it on Home: rhythm mode, camera shadow boxing (beta) and the bag counter, one tap away.
• Profile link: add your website, channel or gym page under your bio.
• More accurate run pace: moving time no longer counts the slowdown before an auto-pause, and live pace uses the distance you actually covered.
• New Journal: your period at a glance, your goal, and a breakdown by sport.
• Redesigned athlete profiles, notifications, fights and picks.
• Many fixes and improvements.
