From February to May 2026, we released three iPhone apps on the App Store: PACE, hajimete and TENSU. We released the third, TENSU, on May 12, which completed the set.

All three are one-time purchases, have no ads, and can be used without registering or logging in. Your records are stored on the device. They can be used in Japanese and English.

PACE: see your pace toward a goal

Released on February 25, 2026.

PACE is an app for goals you track by count, such as "read 100 books this year," "run 20 times this month" or "solve 200 questions before the exam." You set the deadline and the count for a goal, and record what you have done with "+".

  • The remaining count, the remaining days and your current pace are updated each time you record
  • It shows where you are in five levels: fast, a little fast, on track, a little slow and slow
  • Even after a gap of some days, it recalculates the pace for what remains
  • From a home screen widget, you can check your pace and add a record without opening the app (added in version 1.2 in March)
  • You can make goals that repeat every week, month or year. Records can be exported as CSV

In February 2026, it reached No. 1 in the paid ranking of the Productivity category on the App Store in Japan.

hajimete: record first-time experiences

Released on March 16, 2026.

hajimete is an app for noting down the small "firsts" of everyday life, such as a place you went for the first time, something you ate for the first time or something you tried for the first time. "Hajimete" is Japanese for "first time."

  • Record a first-time experience with a date and a short text. There are no categories or tags, so you can use it right after installing
  • Attach a photo to a record. Put a star on records you like
  • With the "reunion" feature, past records come up at random
  • There is no limit on the number of records. They can be exported as CSV

TENSU: give each day a score

Released on May 12, 2026.

TENSU is an app for expressing how your day went as a score from 0 to 100. You choose the day's score from a palette of 21 colors in steps of five points. You do not have to write anything. "Tensu" is Japanese for "score."

  • Each day's score lines up as a color on a calendar. Keep going for a month or a year and you can see the flow of your condition
  • Weekly and monthly averages, the difference from the previous period, tendencies by day of the week, and your highest and lowest days are tallied automatically
  • You can leave reason tags on a score, and look back later at what was connected with good days and bad days
  • In the "Everyone" tab, you can see the distribution of scores other people gave over the past seven days, by region and by age group. Only an anonymous age group, region and score are sent, and nobody can tell whose score it is. We do not collect names or email addresses
