YouTube Shorts, Instagram Reels, TikTok, and even mobile web short-forms —
Dopamine Cat Catches it for you to cut off that short-form viewing time that vanishes in an instant without a notification.
(Patent Application No.: 10-2026-0135363)
■ Recommended for:
- Those who have watched shorts for over 30 minutes after opening YouTube
- Those who can't sleep until late at night after scrolling through Reels
- Those who can't stop on their own and need to force themselves to stop
■ Key Features
🐱 Automatic Short-form Detection and Blocking
It meticulously detects everything from the Shorts tab, inline shorts in the home feed, Instagram Reels, to mobile browser short-form links.
Since the TikTok app itself is short-form, it is blocked entirely while it is open.
You can still use the rest of the features on YouTube and Instagram, such as watching regular videos, feeds, and DMs.
⏰ Daily Allowed Time & Sleep Blocking
Set your own daily limit for how much short-form content you watch. If you exceed the set time, you will be blocked immediately.
If you set a bedtime, you will be blocked immediately during that time without any grace period.
🙀 A Blocked Screen You Can Only Escape by Completing a Mission
You cannot simply close the blocked screen. You must complete one of the following to use it freely again: flipping your phone over and waiting 5 seconds, taking a deep breath, or completing a word puzzle.
📚 Turn Blocked Time into Study Time with Word Puzzles
Filling in the spelling, selecting the meaning, and choosing the pronunciation of English and Japanese words appear alternately.
Basic words are free, and if desired, you can add packs for essential English words for the CSAT (386 words) and basic Japanese for JLPT N5 (360 words).
📈 Continuous Abstinence Record & Weekly/Monthly Statistics
Check your short-form viewing time for today, this week, and this month in a graph, and manage how many days you have been abstaining using Streaks.
🎨 Decorate your blocked screen with various cat characters
Choose your favorite from unique hand-drawn cat characters like Danho-nyang, Malttong-nyang, Yamjeon-nyang, and Pon-nyang, and display them on your blocked screen.
👨👩👧 Parental PIN
If installed on a child's device, you can set a Parental PIN to prevent your child from arbitrarily changing the allowed and blocked time settings.
■ How personal information is handled
- The process of determining which content is short-form is handled 100% within the device and is discarded immediately upon determination. It is not transmitted to a server.
- Usage time records and settings are stored only in the device's local storage and disappear when the app is deleted.
- Anonymous product statistics are transmitted only if manually enabled in the settings; the default value is off.
Even in this case, information on which videos or apps were watched is never included.
For more details, please check the Privacy Policy in the app's settings screen.
■ Please Note
- This app uses the Android Accessibility Service to determine if a screen is short-form. It is used solely for this purpose, and requests permission after explaining the reason within the app.
- Paid word packs and cat skins are optional. Core features such as blocking and missions are all available for free without payment.
- Detection may be temporarily inaccurate if target apps such as YouTube, Instagram, or TikTok are updated. We do our best to address this, but we cannot guarantee 100% blocking.
