Util Monster brings together 1,108 calculators, converters and everyday tools. Check a sale price, compare measurements, count days between dates or explore a loan example in one app. Choose the tool that fits the question, enter your values and read the result alongside your inputs. SHOPPING AND SHARED COSTS Calculate a discount from the original price and percentage. For example, a price of 50,000 with a 20% discount becomes 40,000, saving 10,000 in the same currency. Use percentage calculations for other everyday comparisons. When sharing a meal or another expense, enter the total and number of people to find each person's equal share. UNITS AND TEMPERATURE Convert length, weight and temperature when a measurement uses unfamiliar units. Change inches to centimeters or compare values in different weight units. For temperature, 77°F equals 25°C. Select the units that match your task and review the converted value. DATES AND PLANS Choose a start date and an end date to calculate the time between them. For example, June 1 to July 1 is 30 days. Use the date difference for planning a trip, checking a deadline or comparing periods without counting each day yourself. LOANS, SAVINGS AND HEALTH Explore loan payment calculations with your own example figures. Check a savings goal or see how compound interest changes an example over time. A BMI calculator is also available for a general reference based on height and weight. Results depend on the values and assumptions you enter; they are general information and do not replace financial or health advice. FIND AND REUSE TOOLS Search by name or browse the categories. Add frequently used tools to Favorites and reopen tools from Recently used. Choose from 15 interface languages, adjust unit settings and select a light or dark appearance to suit how you work. The app contains ads. Some tools, including exchange-rate conversion and IP lookup, need an internet connection to retrieve information. Check the inputs, units and any assumptions shown before using a result for a decision.

Verdict

The call

Util Monster's advantage is in-app purchases (none vs 7) and review sentiment (100% vs 66%). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

The Date Calculator PRO holds the better App Store score, 4.7 against 2.8. That said, the two scores are not equally well evidenced: The Date Calculator PRO has 2.6K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of Util Monster's written reviews are positive against 66% of The Date Calculator PRO's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Util Monster ships an update every 98 months, The Date Calculator PRO every 4 months. Both last shipped on November 6, 2026.
