This is the No. 1 LINE compatibility diagnosis/talk analysis app that everyone is using!
This app lets you thoroughly analyze LINE chat content without the other person knowing!
You can even find out your compatibility from your LINE exchanges!
You might discover facts you never knew!
*To ensure safe and secure use of the app, chat content is analyzed within the app terminal without going through the internet.
For example...
Number of chats (number of times you chatted with each other)
Number of stamps (number of stamps sent and received)
Number of calls (number of calls made to each other)
Number of times you said "sorry" (number of times you apologized to each other)
Phrases that you frequently use with each other
The time of day you most often communicate
The day of the week you most often communicate
Whether the number of chats in the last month is higher or lower than the overall average
...and much more! You can accurately find out various information about your exchanges!
[Features of IsTalk]
・Thoroughly analyze your and your partner's LINE chats, learn about your compatibility, and aggregate and display information about your LINE exchanges in an easy-to-understand manner.
・All analysis processing is done offline (without communication with a server), so you can use it safely and securely.
・The analysis results diagnose your compatibility with the person you analyzed. Check out your LINE compatibility with that special someone.
・On the analysis results screen, AI can perform even more detailed compatibility analysis (*Network connection is required to use this function. Please do not use if there are exchanges that contain confidential information, secret information, or personal information.)
・AI "Relationship Mapping" visualizes your relationship on a graph for a smart overview of compatibility.
・Habit screen: see frequently used phrases, peak chat times, and reply speed trends.
・Behavior screen: view chat counts, stamp counts, greetings, apologies, and more.
・Record screen: time-series chat trends, reply time changes, daily averages, and monthly summaries.
・Overall compatibility assessment tracks changes over time with graphed compatibility scores. *Premium only
・Premium service unlocks ad removal and additional features. See "About Premium Services" in FAQ.
・Customize analysis icons from settings. *Some icons are premium only.
・Rankings show TOP 3 compatibility matches and most-chatted partners.
・Group LINE analysis supports aggregation only (no compatibility). Swipe HOME screen to switch views.
*If you cannot analyze, check "What if you cannot analyze?" in settings.
*This app does not use LINE's API. All analysis uses our own unique algorithm.
*We welcome your opinions and requests.
