About this app

Sai is an app that helps you organize the signals you feel in a relationship and calmly compare the choices available to you right now.

There are times when it is difficult to judge on your own whether you should contact someone immediately, wait a little longer, attempt a conversation, or if it is better to keep your distance. Sai helps you organize your thoughts based on the flow of the relationship and your emotional state, rather than letting those feelings get stuck in a vague state.

Sai does not record relationships solely from a person-centric perspective.

You can select and record the current state of the relationship, how much you can convey, and what emotions still remain.

Key Features

- Relationship Signal Analysis
Organizes your current status based on the flow of the relationship, the extent to which you can convey it, and the emotions that remain.

- Compare Action Choices
You can compare possible choices such as contacting, waiting, talking, or keeping your distance.

- Record Your Feelings
You can record actual events and the emotions you felt at the time, and review them later.

- Check Choice Results
You can record how the actions you chose led to subsequent developments. - Saved Sentences

You can save the sentences you want to revisit.

- Sai Map

Explore the next scene that fits your relationship status and find locations using external map apps.

- Backup and Restore

History is saved to your device by default. If needed, you can save and restore it directly using backup files.

Sai is not an app that sends messages on your behalf or dictates the outcome of a relationship.

It is a quiet relationship management tool that helps you sort out your current feelings and choose choices you will regret less.
Organize relationship signals and compare the next choices of contacting, waiting, and talking.
