Convert, save, and time your microwave heating—all in one app. MicroCalc converts the wattage and heating time shown in recipes or on food packaging for the microwave you want to use. A recipe says 500W for 3 minutes, but you want to use 600W? MicroCalc gives you a time estimate instantly, with no manual ratio calculation. ADJUST FOR THE AMOUNT Heating half or double the recipe? Use the slider at the bottom of the screen to choose ×0.5 to ×3, and MicroCalc scales the time in proportion as an estimate. CONVERT AND START A TIMER (PREMIUM) Start a timer directly from the converted result, then pause, resume, or add 10 seconds. If you allow notifications, MicroCalc alerts you when time is up, even when the app is closed. On supported devices, you can see the remaining time on the Lock Screen or in the Dynamic Island. SAVE YOUR FAVORITES Save frequently used heating conditions with names such as frozen rice, drinks, or ready meals (up to three in the free version, unlimited with Premium). Recent conversions are available from your history. Recalled conditions are converted again for the microwave you’re using now. MULTIPLE MICROWAVES (PREMIUM) Add microwaves for home, work, or anywhere else (one in the free version). Set frequent wattages and a practical time increment for each one, and switch between them with one tap at the top of the screen. FEATURES • Convert from 100W to 1500W in 50W steps • Enter minutes, minutes and seconds, or seconds only • View the original conditions and converted result together • Recalculate instantly when the wattage or amount changes • Scale the time for ×0.5 to ×3 the recipe amount • Round up to practical 5-, 10-, or 30-second increments • Start a timer from the result (pause, resume, +10 sec) – Premium • Completion notifications and Live Activities – Premium • Favorites (up to three in the free version) and recent history • Multiple microwaves – Premium • Eight appliance color themes • English and Japanese • Designed for iPhone and iPad FREE AND PREMIUM Conversion, amount scaling, rounding, history, and color themes are free. The timer (with notifications and Live Activities), more than three favorites, and more than one microwave are unlocked with Premium, a one-time purchase. If you got MicroCalc before this version, Premium is included at no extra cost. No ads and no account registration. Conversions and saved data work without a network connection, and everything you enter stays on your device. PLEASE NOTE Times shown by MicroCalc are estimates based on wattage. Times for a different amount are scaled in proportion and are also estimates. Actual heating varies with the food, amount, container, and microwave. Follow the food packaging or manufacturer instructions and check the food as it heats. The timer only tells you when time is up. It does not control your microwave.
