## What is Calc?

A little more joy in your calculations, every day.

Desktop Mate now has a sister app! Calculator - Desktop Mate Widgets is a digital calculator you can use with your favorite characters — and the first release in the new Desktop Mate Widgets series. 

■ Enjoy Cute Character Reactions
Every time you press a calculator button, the character will speak that number and strike a pose. Press "=" to get the answer — though sometimes they might struggle a little to figure it out!
Pet or poke the character's head for special reactions too. Enjoy your favorite character's movements and expressions as you calculate.

■ Customize with Character-Themed Designs
Swap out the calculator buttons and background to match your character's style. Each character comes with multiple design options, so you can mix and match to suit your mood or the moment.

■ Performance Mode: Play Music on Your Calculator!
Tap the music note button to switch from calculator mode to Performance Mode. The calculator keys function like piano keys, and the character will sing along to whatever you press.
Hold "+" or "-" to shift notes by a semitone, and multi-key presses are supported too. With a little practice, you might be able to pull off a real performance! Share your session on social media and enjoy it with everyone.

■ SP Answer Actions: Find the Hidden Numbers
Certain calculation results trigger special character reactions. From a triple "777" to fun number combinations, each character also has their own unique numbers that set off a special response. See how many hidden reactions you can find!

■ Ready to Use Right Away: Aieru-tan
Launch the app and you're ready to go with Aieru-tan, the official mascot character of infiniteloop.
Aieru-tan is a 16-year-old high school student who works part-time at infiniteloop. She loves programming and gaming, and her occasionally sharp tongue is all part of her charm. Since her debut in 2012, she has appeared in Desktop Mate and many other projects as a beloved face of infiniteloop.

■ More Character DLCs for a More Personal Experience
This app also offers paid additional character DLC. The "Hatsune Miku DLC" will be available at launch, with more characters to be added over time in step with the Desktop Mate series lineup.
Each DLC features newly recorded voice lines tailored to each character, so you can enjoy your favorite character's voice and reactions every time you use the calculator.
More characters will be added over time, in line with the Desktop Mate series lineup. And this is just the beginning — more Desktop Mate Widgets apps are on the way. Stay tuned! 

Note: When using additional character DLC, please also review the guidelines set by each character's rights holder.

### 5/5 — works great

*2026-08-27*

I got the Meiko DLC and it has been AMAZING❤️

Meiko Justice!

### 5/5 — Really cool but…

*2026-08-27*

It’s really cool and interesting but why do we have to pay for the vocaloids, can we have just Miku for free?

### 5/5 — Fun, but when will Len come?

*2026-08-26*

Update before reading the rest of this: HES HERE!! LEN IS HERE!! IM SO HAPPY HES HERE !! Anyways back to original review: It’s really fun to hear the characters say the numbers, and I think it’s funny how they sometimes overthink it. I know overthinking is a setting though and can be changed. I hope the Kagamine Len option comes out soon though, since I don’t wanna buy Miku and then only use Len 😓 that is another thing to beware of, you have to buy the characters. I’m not sure if the different vocaloids are separate packs or not, that’s why I’m waiting for it to come out.

### 1/5 — this sucks dude

*2026-08-26*

i found this app through an instagram reel showing off the vocaloids but you have to pay for all of them. why?? why advertise the vocaloids but not show the free character nor that you have to pay for the vocaloids? it’s very stupid and you should disclose in ur ads that the vocaloids are not free

### 5/5 — Very cute！

*2026-08-26*

love it

### 5/5 — Very Good but need more free character

*2026-08-24*

I wish there were more free cute characters but it’s still great

### 5/5 — My life has changed

*2026-08-23*

No note, it’s perfect

### 4/5 — Cool app missing features

*2026-08-23*

Great app please add a history button that shows previous entries

### 4/5 — unique

*2026-08-23*

its a fun calculator, creative idea and way more amusing than the typical one. however im quite disappointed by the cryptons such as miku, luka, rin, len and soon to be meiko & kaito being locked behind a paywall. i think instead they could have a wider variety of characters and then a gacha system where you gotta use the app enough to get tokens for characters. then you could incorporate ads to get more tokens. you could also have a variety of collabs that would make so many fandoms come to this to get a specific character for their calculator. character could be ranked by their difficulty and rolled for. but enough of my ideas. this app is pretty cool and i will probably keep it for a while. 8/10 from me.

### 5/5 — miku

*2026-08-22*

i wish miku was free 😭 but ts is peak
