Weight increments, number wheels and direct entry

Adjust weight using each exercise's increment. Switch between the wheel and direct entry, and change reps, time and RPE on the spot.

App screenshots are shown in Japanese. The steps and captions below are in English.

Zero reps and an empty field are different states. Clearing a required value in a completed set triggers validation, so a set cannot remain confirmed with required fields blank.

How to use it in a workout

  1. Save the exercise's weight increment

    Open More → Exercises, edit the exercise, enter its weight increment and save.

  2. Open a value on the logging screen

    Tap a field such as weight to open the wheel. Check its unit and field type before selecting a value.

  3. For a distant value, choose Enter a number

    Choose Enter a number in the wheel to type a value directly. Check any validation message before confirming.

  4. Confirm and log the set

    Choose Confirm to return to the logging screen, check the actual values and complete the set.

  5. Configure multiple exercises together

    Open bulk settings from More → Units, then choose kg/lb, the increment and whether to overwrite existing settings. Check the number of affected exercises before applying.

Choose weight increments to suit your equipment

Use exercise-specific settings, such as 5kg steps for a machine and 2kg for dumbbells. Saving an exercise's weight increment and default values sets the basis for ± in the next workout.

In bulk unit settings, choose kg/lb and an increment, then decide whether to overwrite individual settings. To preserve detailed settings for particular gyms, check the overwrite option and affected count before applying.

kg/lb and the sign of added weight or assistance

After changing display units, check kg/lb beside the input. In assisted pull-ups, a negative value in the added/assistance weight field indicates assistance. Negative values in the ordinary weight field do not have that meaning.

Reps and seconds are integers; RPE has a defined range and increment. If an input is rejected, correct it using the reason shown beside the field. Numeric custom fields have different types and restrictions from basic values.

Case: direct entry for large changes, ± for small ones

Set the chest press increment to 2.5kg. From last time's 52.5kg to 55kg takes one + tap. When using different equipment at 40kg, use direct entry, confirm and enter the reps. Later, review whether you used 55kg or 40kg alongside that day's equipment.
