Compatibility Tester
The Compatibility Tester is a feature in Tomodachi Collection and Tomodachi Life that lets the player measure the compatibility between any two Miis, provided they have a complete birthday profile saved. It is unlocked by having at least two male and two female Miis on the island, and having at least 15 problems solved. Unlike other locations in the game, it is not a building or specific area, but rather a device used by the player.
Functions
The tester is used to determine the compatibility of two Miis. This can be romantic or platonic. When two Miis, one of each gender, are tested, they will be tested as friends if they are the same gender, family, or of different age groups, and will be romantically tested if they are the opposite gender and the same age group. In the Japanese version, since Miis of any age can date each other, age is not a factor in the compatibility tester.
The results of the compatibility tester in all functions do not judge how Miis will get along in the game itself; the game describes it as being "just for fun" and has no effect on their actual relationships. Compatibility tester results are calculated roughly through horoscope information given through the Miis' birth dates, while how Miis get along in-game is affected both by their set personalities and by the interactions they have with each other, including conversations and fights.
Compatibility Rating
Compatibility ratings score the chemistry between two Miis as a flat percentage, from 0% to 100%. Every ten points, the relationship gets a different title and description, and a different music track will play alongside it. Friendship rankings use a yellow color scheme while romance rankings use a pink color scheme. While two Miis are being tested, they will appear with their heads on human-proportioned bodies, with male Miis wearing shirts and ties, and female Miis wearing blouses and skirts. The Miis will also pose together depending on their rating. Friendship rankings and romance rankings have different names, comments, poses, and music tracks.
Compatibility Forecast
The compatibility tester can also give a "forecast" to see how the two selected Mii characters will interact in the following week. The function forecasts the relationship in the categories of Work/Study, Chats, Leisure, and Love (the last category is omitted if the Miis cannot be romantically tested). Each day will display a visual weather-based rating for each category, going from full sun (best) to full storm (worst). Text scrolling along the bottom of the chart provides a comment on one category or a summary of the whole chart.
Regional differences
The Compatibility Tester does not have many differences. In the Japanese version, various piano tracks will be played in the background, carried over from Tomodachi Collection. In the international releases of the game, jazz saxophone tracks will play instead.
Also in the Japanese version, in the Mii News report, two Mii characters of the same sex can be seen looking at each other. This may have been changed due to possible romantic implications. In all other versions it will be a male and female Mii looking at each other.
