ナラブ - 行列待ち時間予測アプリ

This app eliminates the worry of "How long will I have to wait in this line...?"

Narabu is an app that predicts lines and waiting times at popular restaurants using AI and user reports, and displays them on a map with color coding. The more people use it, the smarter the predictions become every day.

🟢 Green = Ready to enter immediately / 🟡 Yellow = Slightly crowded / 🔴 Red = Extremely crowded
Simply open the map to see at a glance which restaurants are currently open and which are worth waiting in line for.

■ When to use it:
・You want to go to a popular ramen restaurant, but you don't know how long the wait will be.
・You don't want to go all the way there only to be turned away by a long line.
・You want to find a popular restaurant nearby that you can enter right now.
・You want to know the crowd situation at your weekend destination before you leave.

■ Features of Narabu
1. AI predicts even for restaurants without data from day one.
The AI ​​predicts a baseline waiting time based on the time of day, day of the week, weather, and restaurant genre. It automatically adds popular restaurants with many reviews and long lines to the map, so it won't just show "restaurants that aren't registered."

2. Getting Smarter Every Day with Everyone's Reports
People in line report "how many people ahead of me and how long they waited" in 10 seconds. The more reports we collect, the more accurate our predictions become. You earn points and badges for reporting.

3. Honest Display of Prediction "Reliability"
Stores with few reports are clearly marked as "AI Prediction (Reference)." This is an honest wait time prediction, not a wild guess.

4. More Advanced Features for Those Who Want More
Features for those who want to thoroughly avoid lines, such as availability notifications and weekly congestion graphs, are available in premium (you can try it free for 3 days).
