Danilo Campos

I’m Danilo Campos, an iOS developer and product designer since 2008. I sponsored DF this week to share two things:

• My new iPhone app, Tallymander
• I’m available on a freelance basis for product planning, interaction design, and iOS/macOS engineering

Tallymander is a tool for gathering and analyzing numerical data. Spreadsheets never quite hit the spot for me in a mobile context, so this is an attempt to reimagine them for your pocket.

I built Tallymander with SwiftUI, and I know my way around Objective-C, Swift, AppKit and UIKit.

Let’s talk about your project.

This RSS sponsorship ran on Monday, 15 June 2020.
