## What it is
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

## Facets
- artifact type: library
- maturity: stable
- function: formatter, ui-components, form-handling
- domain: mobile-development, android-tools, developer-tools
- platform: jvm
- tags: input-masking, text-formatting, phone-numbers, kotlin, android, form-input, mobile
