For each child, the app lets you know if they are currently in a mental leap period. By understanding these developmental phases, you can better support your child's growth and emotional development. Make parenting a little easier and more joyful every day.
CheckBuy
A smarter, easier way to manage your shopping list. This app is a smart shopping list tool that gets better the more you use it. It remembers your frequently visited shops and the items you often buy, helping you build your list faster and more efficiently every time.
Income Calculator
This comprehensive take-home pay calculator supports three types of employment: employees, sole proprietors, and corporate officers. It accurately calculates your actual take-home pay by considering various taxes and social insurance premiums. The calculator automatically computes resident tax, income tax, and social insurance fees from your annual income, displaying your net pay in real-time. It stays updated with tax law changes and always uses the latest tax rates for calculations. Perfect for future income planning, comparing salaries when changing jobs, or estimating side business income.
MORA (Mortgage Calculator)
An app that makes it easy to simulate mortgage loan repayments. Simply enter the loan amount, interest rate, and repayment period to instantly calculate monthly payments and total repayment amounts. It supports both equal principal and interest, and equal principal repayment methods, allowing you to compare multiple repayment plans to find the optimal loan strategy. Supporting one of life's biggest financial decisions with reliable numbers.
Piyo Garden
A tiny game land full of chicks. Gentle enough for children as young as five, yet fun for grown-ups too — no instructions needed, no tricky rules, and no scary way to fail. It packs nine mini-games: a soothing garden where tapping chicks hatches more eggs, plus whack-a-mole chick tapping, jumping, egg catching, hide-and-seek, racing, stacking, music tapping, and spot-the-different-chick. No ads, no in-app purchases, and no data collection — and it works offline, anywhere.
