Instead of keeping blacklist notes in many different apps, users can gather them in one place and check them later with simple search fields.
Coratina
A blacklist app that helps you keep service records clear and easy to check.
Blacklist Assistant is Coratina's iPhone app for individuals and families. It reads screenshots from ride-hailing, delivery, courier and housekeeping apps, helps users check who they are looking at, and keeps clear blacklist records for later.
The app is made for daily use by individuals and families who want a simple way to remember who they do not want to meet again.
The long-term value is the organized blacklist entry itself. That makes searching, sharing and device recovery much easier later.
Core Capabilities
Three things the app needs to do well
The goal is simple: understand the screenshot, help the user check the person, and keep the result in one place that stays useful over time.
Read Screenshots
The app can scan recent screenshots and pull out useful information such as names, phone digits, plate numbers and service details.
Check Existing Records
When the screenshot shows enough information, the app can compare it with existing blacklist records and tell the user whether this person has appeared before.
Keep Records Together
Records from different apps should not become a mess. The app keeps them together in one place so users and family members can search and review them more easily.
Recognition Flow
How a screenshot becomes a record
The app does not need users to explain every screenshot. It should do the basic work first, then only ask for help when the result is still unclear.
Find the screenshot
The app scans recent screenshots or receives one directly from the share sheet.
Extract key details
It looks for useful fields such as names, phone digits, plate numbers and service-related information.
Check or save
If the screenshot is for a quick check, the app compares it with existing records. If it is a post-service page, the app can help save a new entry.
Keep it organized
The result stays in the user's personal library or shared group so it can be searched, reviewed and recovered later.
Sharing & Recovery
Built for everyday use, not just one-time checks.
Users need a list that stays clear over time. That means easy search, family sharing and a recovery path that still works after switching phones.
Quick checks
Recent screenshots can be checked first when users reopen the app.
Family sharing
Group ID + group passphrase
Account recovery
Account, password, recovery code and local backup
Long-term use
Cloud sync + local backup
