Originals have soldered on speakers while replicas have coil speakers, causing them to have louder sound. On the 2017 rerelease, the Tamagotchi will make more calls than necessary to fill the discipline meter. However, the user must also respond to the extra calls; missing calls, even when the meter is full, will affect which adult the Tamagotchi will grow into. On later models, special animations play at specified hours throughout the day, each inspired by the franchise the model is based on. These animations will stay on screen for three minutes before disappearing on their own. Pressing any button will end the animation, but in some cases may trigger an additional animation to play.

The Tamagotchi features a Health meter screen that shows the Tamagotchi's overall stats. The first screen displays age (one year being the equivalent of one day) and weight (measured in grams on the Japanese versions, ounces on international P1s, and pounds on international P2s), the second displays Discipline, the third shows Hungry, and the fourth shows Happy. There are a total of four hearts each for hunger and happiness, with white hearts representing an empty stat. The rate at which hearts decrease depends on the character, and also how old they are in regards to adults. Using the Health meter regularly allows the user to know their Tamagotchi's needs, allowing them to make decisions that influence the Tamagotchi's overall care, which in turn impact the Tamagotchi's evolutions throughout its life cycle.
