[Sequel] The Story of Creating the Sister App "Love Layer" to Fate Layer Using Only a Smartphone | Compatibility Diagnosis App Released Completely Free
Introduction
Following the fortune-telling app "Fate Layer" released the other day, its sister app "Love Layer" is now complete.
After receiving feedback from those who read about Fate Layer asking, "Can't you also do compatibility diagnosis?", I decided to make one. Once again, this was done using only a smartphone, only Japanese, and zero cost.

App Overview
Love Layer is a compatibility diagnosis app where AI generates authentic compatibility readings based on two people's dates of birth and full names.
Here are the main features:
・Just enter the two people's dates of birth and full names ・Compatibility calculation using astrology, Nine Star Ki, numerology, and name analysis ・Displays a compatibility score (0-100 points) ・AI generates detailed reading text ・Supports various relationships such as romantic, friendship, parent-child, and work ・Supports 5 languages (Japanese, English, Chinese, Korean, French) ・Uses completely free Groq API ・Android native app version available
Just like with Fate Layer, I created this by simply talking to Claude in Japanese.

1. Differences from Fate Layer
While Fate Layer is a fortune-telling app for one person, Love Layer is a compatibility diagnosis app that requires inputting information for two people.
The main differences are as follows.
Fate Layer: Enter one person's date of birth and full name -> 5 types of fortune-telling: today, this week, this month, this year, and overall. Love Layer: Enter two people's dates of birth and full names -> Compatibility score + detailed compatibility reading.
The design has also been changed from Fate Layer's gold and night sky theme to a mystical pink-themed design. You can use them side-by-side as sister apps.
2. Development Process
Based on the source code of Fate Layer, I spoke to Claude as follows.
"Please create a compatibility diagnosis version of Fate Layer. Please allow input for two people's dates of birth and full names, calculate compatibility using zodiac signs, Nine Star Ki, numerology, and name analysis, and display a score and a reading. Please make the design pink-themed."
With just this, the basic structure was completed. After that, I made minor adjustments to finish it.
