Latest release
What’s New
v1.3.0 Improvements & Fixes - Fixed an issue where tapping a saved record to edit it did not show your previously entered values (back counts, deductions, memo). - Improved behavior when changing the date while editing a record: switching to a day with a record now shows that day's content, and a day without a record resets to the initial state. - Clarified some wording in the in-app Help guide. - Minor bug fixes and stability improvements. Your existing data is preserved.
