An Android library written in Kotlin that applies pattern-based masks to user input in text fields, guiding users to enter correctly formatted values. It supports phone numbers, dates, card numbers, IBANs, and number/currency formatting, with country guessing for international phones.

Use cases

• format phone number input in an android app
• mask credit card number as user types
• validate and format date input fields
• format currency input in a text field
• apply IBAN formatting to user input
• extract digits from masked phone input
• guide users to enter serial numbers in a fixed pattern

When to choose

• you need pattern-based input masking on Android text fields
• you want automatic country detection for international phone number formats
• you need currency or number formatting tied to user input
• you want a mature MIT-licensed Kotlin library with an iOS counterpart

When to avoid

• you need input masking on platforms other than Android
• you need fully custom validation logic beyond pattern templates
• your project is not using Kotlin
