ond is a conditioning app that records the rhythms of your mind and body as “waves.”
Observe your inner waves without judging them. ond helps you capture your rhythm through two connected waves: your mind and your body, so you can begin to notice the patterns that are uniquely yours.
— Mind Wave
Check in each day and record your condition on a 0–10 scale. With neutral 5.0 as the center, your ups and downs become a smooth, beautiful wave chart over time.
・ Quick recording with an intuitive drag slider
・ Wave charts for 7 days, 30 days, 90 days, and more
・ Automatic ABOVE and BELOW summaries and comparison

— Body
Training logs, weight trends, steps, and sleep. By seeing your mind and body together, you can look back on your rhythm with more depth.
・ Detailed logs for exercises, sets, and weight

・ Step comparisons and goal display
・ Sleep records and Health app sync
・ Weekly volume and top set calculations

Ratings & Reviews
This app has not received enough ratings or reviews to display an overview.
・Opening the app on a weak connection or in Airplane Mode no longer signs you out. Your signed-in screen and plan appear as soon as the app opens.
・Signing out now applies only to that device. Your other devices stay signed in.
・The question about combining records from guest use now appears only when records you entered yourself are going into a different account. Signing back in to the same account combines them without asking.
・Sliding your finger along a chart now gives a light tap each time it moves to another day. The check-in slider ticks at each step and taps a little harder at 5.0, so you can feel where you are without watching the screen.
・On TODAY, the wave chart now sits right below the check-in, so you can see how your wave is moving before reading today's summary.
・Fixed the 90-day, 1-year, and All views of the wave, where periods without records were squeezed out and the records around them looked stretched. The timeline now follows the actual dates.
