Calkoo provides users with calculators for almost any purpose. The application compiles all of its calculators on its homepage, where users can browse categories including measurement, wage, taxes, capital budgeting, cost of capital, stock analysis, mathematics, loans, health, saving and more. Clicking on the corresponding icon takes the user to their calculator. Each calculator includes various fields based on the type of calculation being done. Some utilize radio buttons and drop down boxes while others ask for numbers only. Users can visit Calkoo to complete almost any kind of calculation they could possibly need on an average day. The website doesn’t tailor its calculators to any specific industry, so everyone from stock brokers to math teachers and students can use the website as an easily accessible calculating tool.

Calkoo was created by Trinity Capital to provide users with an easy way to complete calculations online. The current version includes a wide selection of calculators in multiple languages. Language options include English, German, French, Spanish, Italian, Portuguese and Russian. The website does not enjoy extensive popularity however it does function as a practical tool to the few users who frequent the website. New calculators are added, with the most recent additions including an area and volume calculator.

Calkoo isn’t much like other applications that handle calculations. Although there are some that strictly serve as calculators, many websites contain calculating tools intended for a specific purpose or industry. Calkoo is one of the few websites that explores all of its options to include a diverse collection of unique and common calculators. Users can handle a number of tasks, including some rather complex calculations, by visiting the homepage and choosing a tool that suits their needs.

Calkoo is intended for one purpose: calculating. The website design seems to support that by providing a clean, neat and organized list of calculator links accompanied by matching blue icons under blue headers. The design works well because, plain as it may be, it allows the user to quickly browse and find the calculator the need. The site includes a handful of advertisements, but these do not mingle among the calculator links so they stay well out of the way.

Calkoo serves a practical purpose, but not one that demands the user of an account. All visitors to the website can use as many calculators as they like. There is no account requirement (since there really would be no reason to have an account). This helps streamline the user’s ability to visit Calkoo, find a calculator and use it without having to worry about a username and password. There is no indication that an account option will be added anytime in the future.

All users are welcome to calculate to heart’s content on Calkoo. There are no limitations and no registration requirements. As soon as the visitor arrives, they can access all calculators currently available on the website. The site includes a few advertisements, which help cover the cost of maintenance. Charging a fee would only discourage users from trying Calkoo. The application is very convenient for anyone who calculates often, however the free price tag is right where it should be for this type of service.

Calkoo is perfect for anyone who needs to do a few quick calculations. It is especially useful for students, teachers and anyone who frequently works with numbers. Some of the calculators are not as practical, however there are many standard options so that every visitor can find something to help them work out a problem or make an estimate. The site only becomes more useful as additional calculators are added.
