Lifetime rating
5.0★
recent stars not readable yet: new ratings are a tiny share of the total
Review momentum
50/100
faster than 50% of Lifestyle apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Rainbow Days: Mood Journal
The smallest journal you will actually keep.
Pick one of seven rainbow-colored moods and add a single line (up to 60 characters). On busy days, a mood alone is enough.
KEY FEATURES
- Log one entry per day: a 7-level mood (from Excellent to Terrible, one rainbow color each) plus a short note
- Year in color: see your whole year as a grid of mood colors
- Monthly calendar with a count of days for each mood
- Mood charts: your daily ups and downs for the month, and a month-by-month breakdown for the year
- "On this day": see what you wrote on the same date in past years
- Streak counter for consecutive days
- Add, edit, or delete entries for past days
- Long-press the app icon on your Home Screen to log today's mood in one tap (Excellent, Good, Okay, or Not great)
- Daily reminder at the time you choose (skipped on days you've already logged)
- Lock with Face ID, Touch ID, or your passcode
- Supports Dark Mode, larger text, and VoiceOver
- Available in English and Japanese
MADE TO STICK
No long entries, no blank pages. Tap a mood, jot a line, and watch your calendar fill up with color.
PRIVACY FIRST
- Everything stays on your iPhone. Nothing is sent to a server
- No account, no ads
- With the lock on, the app asks for authentication every time you open it, and your entries are hidden in the app switcher
REQUIREMENTS
iPhone with iOS 18.0 or later
Deleting the app also deletes your entries (backup and transfer to another device are not supported).
