Bio

Daniel earned his master's degree in computer science specializing in computer security, and then worked for three years in an eCommerce company. After creating an iPad/iPhone app for them, he decided to branch out and develop apps full-time. Since then, he has created over 15 apps as the sole coder and more apps working with a team. Daniel truly enjoys iOS development and is highly skilled at it.

Cash Register Point of Sale App

I created this app as the sole programmer. It processes payments, takes orders, has a place where you can view and update customer information, and also view customer purchasing habits. The app uses the Square SDK for payments. Previously, I integrated the app with two other payment providers, including a hardware credit card reader and payment processor.

Fatal Encounters

https://fatalencounters.org/
As the sole programmer, I created a video and audio recording app which uploads the data in real-time to a server, for recording police encounters.

I recruited a designer to assist in creating a beautiful look for the app.

The app integrated with Amazon's AWS for storage of the recordings.

The project was for a non-profit dedicated to increasing police accountability.

Invoice Maker Pro

I developed the first iOS version. I recreated an Android app for creating billable invoices, in Objective-C, with the appropriate redesign.

The client greatly appreciated the speed of the iOS rewrite, the quality of the code, and the smooth interface.

A Tinder-like Dating App

This was contract work where I had to re-skin a social-network, dating app and add functionality, including impressive animations and graphs.

The work was completed timely, resulting in a smooth interface that went above and beyond requirements.

Aurora Concept App Used in Their $160K Kickstarter

I had contract work to design, prototype, and implement an app to communicate over Bluetooth Low Energy with an EEG headband. The iOS and Android concept apps were used in a successful Kickstarter campaign.

Dashboard Plus

As the sole programmer, I created an app that receives your latest business statistics directly on your phone and sends notifications for online sales.

The app had an optional "Ka-ching" cash register sound that could play when clients had online sales.

Photo Investigator

https://photoinvestigator.co/
The Photo Investigator is a powerhouse metadata editor for iOS. The app can edit more metadata than any other iOS app, with over 300 fields. Also with support for editing profiles and bulk editing.

This is an independent project of mine. It inspects or removes all photo metadata: GPS, EXIF, XMP, IPTC, size, date, and more.

Free Sudoku Solver

https://apps.apple.com/us/developer/daniel-anderson/id434333497
This is an independent project of mine. A Sudoku solver with a clean, quick, and easy user interface.

The app has been very well received for its smooth interface, including a mode to import a puzzle using computer vision.

Vivid Sudoku

https://itunes.apple.com/us/app/vivid-free-color-sudoku/id756176898?mt=8
This is an independent project of mine. A Sudoku game with a beautiful and vivid color scheme.

Magic Phone Cleaner

I built this blockbuster iOS app with over 5 million downloads. I've since removed it from the App Store. The app was able to remove cache and temporary files on a phone, which could clear up as much as 5 gigabytes with just the tap of a button.

Creator AI Tools

I was the sole developer of a React-based web app for using ChatGPT to provide personalized replies to content from the YouTube API. The back end is written in Spring Boot.

ChatGPT provided user customization results in excellently crafted replies to user comments.

Boycott That!

https://apps.apple.com/us/app/boycott-that-by-savetmr-com/id1515041024
A Java-based Android app to assist consumers in making ethical choices when purchasing.

The app is written in Objective-C for iOS and a separate codebase in Java for the Android version, with both using the same data.
