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.

Verdict

The call

The clearest difference is ads: Calc at none against Yumeshipper's shown. Calc also leads on review sentiment (73% vs 63%) and device support (4 vs 1). Yumeshipper's advantage is rating (4.5 vs 4.1) and ratings volume (1.5K vs 52). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. Yumeshipper sells 10 in-app purchases, starting at $4.99 per month and Calc sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Yumeshipper holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Yumeshipper has 1.5K ratings behind it against 52, so its average is the more settled of the two. Written reviews complicate that: 63% of Yumeshipper's written reviews are positive against 73% of Calc's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Yumeshipper ships an update every 3 days, Calc weekly. Both last shipped on November 13, 2026.
