About the app
Huedora is a daily color memory game for iOS. Everyone gets the same color for one second, then rebuilds it from memory with hue, saturation, and brightness sliders. Your score is color match accuracy — how close your mix is to the target. Play alone, climb Game Center boards, or create a private friend group. The daily color, practice, groups, and leaderboards stay free. An optional $2.99 Lifetime unlock adds unlimited practice, Gauntlet, Duel, and palette export.
Wordle made a daily ritual out of letters. Huedora does it with color.
Every day, the same color appears for exactly one second — then it’s gone. You rebuild it from memory by dragging three sliders: Hue, Saturation, Brightness. When you submit, Huedora measures the perceptual difference and shows your color match accuracy as a percentage you can share.
One attempt a day. Same color for everyone. A Wordle-style share card that fits a group chat. Optional private groups with a join code so friends can compare scores and streaks — without ever spoiling the day’s color before someone has played.
Most of the game is local-first and works offline. Scores, streaks, and your palette archive live on your device. Groups are the only feature that needs a network: Sign in with Apple once when you create or join, and only scores, streaks, and membership sync — never the colors themselves.
Free forever: today’s color, limited practice, groups, Game Center leaderboards, and sharing. Want more practice and the Lifetime modes? Unlock once for $2.99 — no subscription. If you run out of free practice, you can optionally watch a rewarded ad for +3 practice that day (twice max). No banners. No interstitials. Lifetime owners never see ads.
Huedora is a game about matching a color you just saw. It is not a training program, not a medical tool, and not a claim about cognition. The number on screen means one thing: color match accuracy.
How it works
See today’s color
The screen fills with the daily color for one second. Everyone worldwide gets the same one.
It disappears
The canvas goes neutral. No peeking. Rebuild from memory.
Mix with H / S / B
Drag hue, saturation, and brightness until the live swatch looks right.
Get your accuracy
Submit to see color match accuracy and a side-by-side of target vs guess.
Share or challenge friends
Post a Wordle-style share card, or join a private group board with a code.
What sets it apart
Memory, not hex literacy
You don’t type codes. You remember a color and rebuild it.
One global daily color
Same challenge for everyone. Perfect for a standing ritual in a chat.
Honest scoring
Color match accuracy from perceptual difference (CIEDE2000), not a vibes meter.
Groups without spoilers
Boards show scores and streaks only. The day’s color never appears in group UI before you play.
Local-first core
Daily play, practice, and history work offline. Groups are the optional online layer.
Clean monetization
Free daily + groups. One $2.99 Lifetime unlock. Rewarded ads only if you opt in for extra practice — never forced, never banners.

|---|---|---|
| Core loop | See color 1s → rebuild from memory | Hex guessing, quizzes, or endless levels |

| Account for core play | Not required | Often required |
| Friend groups | Optional join codes; scores only sync | Rare, or requires full social accounts |

Speed & privacy, at a glance
Fast
- A full daily round takes under 20 seconds once you know the loop.
- No account required to play today’s color.
- Share card is built for a group chat — emoji gradient + accuracy.
- Practice, Gauntlet, and archive stay on-device when you’re offline.
Private by design (honest, not absolute zero-cloud)
- Play history, streaks, and palette archive store locally on your device by default.
- Groups are optional and use Sign in with Apple; servers store group membership, nicknames, scores, and streaks only — never target or guessed colors.
- Game Center leaderboards use Apple’s Game Center (when you sign in).
- Purchases go through Apple; Lifetime entitlement via RevenueCat.
- Optional rewarded ads use Google AdMob with non-personalized ads; Lifetime owners never see them.
- No third-party analytics SDK for product analytics in v1.
- Delete the app to remove on-device history. Group membership can be left from inside the app.
Color match accuracy — and display honesty.
Screens differ. True Tone, Night Shift, brightness, and panel variation change how colors look. For a fairer shot, turn off Night Shift and raise brightness. Leaderboards reflect color match accuracy on your device; display variance is real, and we say so up front. Huedora does not claim to train memory, improve perception, or measure cognition.
“One color. One second. One shot a day.”
“Wordle for color memory.”
“Your score means color match accuracy — nothing else.”
“Groups sync scores, never colors.”
“$2.99 once. No subscription. No banner ads.”
Frequently asked questions
Q.How much does Huedora cost?
The daily color, limited practice, groups, Game Center leaderboards, and sharing are free. Huedora Lifetime is a one-time $2.99 unlock for unlimited practice, Gauntlet, Duel, and palette export. No subscription. Optional rewarded ads can add practice for free users; Lifetime owners never see ads.
Q.What is “color match accuracy”?
It’s how close your rebuilt color is to the target, measured with a perceptual color-difference formula (CIEDE2000) and shown as a 0–100% score. It is not a cognitive or medical score.
Q.Can I replay today’s color?
Daily is one attempt. Practice mode uses random colors (3 free per day; Lifetime unlocks unlimited). Free users can optionally watch a rewarded ad for +3 practice, up to twice per day.
Q.Do I need an account?
Not for daily play, practice, or local history. Sign in with Apple is only asked when you create or join a friend group. Game Center is optional for global leaderboards.
Q.What do groups sync?
Only scores, streaks, nicknames, and membership — never the day’s color or your guess colors. Group boards never spoil the color before you’ve played.
Q.Does it work offline?
Yes for daily, practice, Gauntlet, Duel, and your local archive. Group boards need a connection.
Q.What languages does it support?
