The morning-and-evening format with fixed prompts builds a solid reflection habit, and the product has a loyal core with 7-9 years of use. A serious problem: entries disappear without warning during updates and support is slow to respond.
評価点：Splitting the day into a morning and evening session structures the day and makes reflection a predictable habit.
不満点：The mood tracker does not function properly, and prompts do not adapt to the user's schedule.
向いている人：Those who want a short morning and evening positive reflection practice
365 Gratitude builds a gratitude practice through daily stories, prompts, and mini-tasks. Many users stick with it for a year or more and report a real shift in mindset. The main weakness is content that sometimes repeats and an interface that is small and hard to read on a phone.
評価点：A daily story and a specific reflection question make it easier to get into the right headspace than staring at a blank page.
不満点：Almost no mood pattern analytics: the app motivates but does not show how your state evolves over time.
向いている人：Those who want to build a daily gratitude practice with ready-made content
A simple gratitude journal with good prompts and a vision board. Serious data loss for several users and complete silence from support badly undermine trust.
評価点：Themed challenges and the vision board keep users engaged with the practice every day.
不満点：A hard streak reset after missing one day works against the user rather than for them.
向いている人：Those who want a short morning gratitude practice
Being Me offers a structured approach to journaling: morning and evening prompts, habit tracking, goals. Many users stick with it daily for months. The weak spot is an interface that feels cluttered in places, and the mobile-only format limits those who want to write at length.
評価点：Ready-made morning and evening prompts make it easy to start even for those who have never kept a journal.
不満点：Mood analytics are thin: the app collects data but shows almost nothing in the way of patterns or trends.
向いている人：Beginners who want to build a journaling habit with the help of structure
A lean gratitude journal with a well-calibrated structure: three items a day, a daily quote, and a PDF summary for any period. Reminders occasionally fail and the PDF export is sometimes incomplete.
評価点：The three-point format is small enough to do every evening and specific enough to actually work.
不満点：No streak counter and no way to jump back to a past entry without scrolling through a long list.
向いている人：Those who want to build positive thinking habits without much effort
