Many forms are filled in on a phone, whether by a customer on the go or by field staff away from a desk, so mobile usability is not optional. A mobile-friendly form loads quickly, fits the screen without pinching or scrolling sideways, and keeps tapping and typing to a minimum. If a form is awkward on a small screen, people abandon it or make mistakes.
Forms built in Kolaytik are designed to adapt to the device they open on, so the layout reflows to fit smaller screens automatically. To make the most of this, keep forms concise and arrange fields in a single clear column that flows naturally from top to bottom. Favour dropdowns, toggles and selectable options over long free-text answers, since they are far easier to complete with a thumb.
A few habits go a long way. Use short, descriptive labels, break long forms into logical sections, and only ask for what you truly need. Features such as file uploads and signatures work well on mobile when they are placed where they make sense in the flow. By designing with the phone in mind from the start, you get forms that are comfortable to complete anywhere, which means higher completion rates and cleaner data.
