Tip calculator for seniors

Easy to use tip (gratuity) calculator app for all users including older users as well as some visually impaired users. The app is particularly helpful for users who have not used apps or are not comfortable with apps. Even a grandma or grandpa (with no app experience) can use it. It can be used for one or multiple payers as a tip and split calculator. Large print and large keys are helpful to see and type correct numbers for all including elderly users. Voice assistance makes it easy to navigate through the app for all users, particularly users with visual impairment (low vision). This intuitive app can be used for a single payer or when multiple people are splitting (dividing) the bill equally. It can be used to compute tips in many situations, for example, after a meal or drinks in a restaurant, delivery of pizza or other food, a taxi ride and delivery of groceries or medicines. The app makes it very simple to calculate tips, especially for senior citizens and users with reduced ability to see, including some legally blind users. Large print may enable users to use this app without reading glasses or other visual aids. See "How to use the app" below.

Since the app does not use any particular currency, it can be used in any country that uses the Western Arabic numerals and a decimal point as a decimal separator. For example, the app can be used by English speakers in the United States (USA), Canada, Mexico, Dominican Republic, the United Kingdom (UK), Ireland, Australia, New Zealand, England, Scotland, Israel, Egypt, Malaysia, Singapore, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, Sri Lanka, Thailand, and The Philippines. Users in many other countries, such as, Argentina, Armenia, Austria, Belarus, Belgium, Brazil, Chile, Czech Republic, Denmark, Finland, France, parts of Canada, Germany, Greece, Italy, Indonesia, The Netherlands, Norway, Poland, Portugal, Russia, South Africa, Spain and Sweden, who usually use decimal comma as a decimal separator, can use this app by replacing the comma with a period (point). For example, they can use the app successfully by entering 35.74 instead of 35,74.
