Jarvis

Everyone wants a Jarvis. I built mine.

Desktop and mobile app
Built for one user

Every other project on this page was built for other people to use. Jarvis is the opposite: a native desktop app and a mobile app with a user base of exactly one, me. It is my personal assistant, and it runs my day.

The heart of it is my daily score. Every day Jarvis measures three things and gives each one a weight. How many of the tasks I laid out for the day I completed, worth 40 points. How many of the habits due that day I did, worth another 40. And how I feel, worth the last 20. Together that is one number out of 100 for the day.

The Jarvis overview showing a 96 percent ring for Monday, with bars for tasks 40 of 40, habits 40 of 40 and feel 16 of 20, above that day's task and habit lists — A 96 on a Monday: every task done, every habit done and a 16 out of 20 on how I felt.

One day on its own means very little. The reason I score them at all is the progress screen, where the days line up beside each other and the shape of a month appears: which week beat the one before it, which part of the score is carrying me and which part is quietly slipping.

The Jarvis progress screen with a bar chart of daily scores, a weekly average of 84 that is down 15 from the week before and a breakdown showing tasks at 100 percent, habits at 93 and feel at 75 — An 84 week, down 15 on the one before it, and the breakdown that explains why.

Around that score sits everything I used to spread across other apps. A to-do list with deadlines and priorities. A habit system for the things I want to do every day or a few times a week. And one feature that is very personal: progress photos, so I can watch how my body changes over months of showing up at the gym.

Then there is the health section, which does three things. I create my own workout plans, no AI involved, and track every workout against them, so I can see how closely I follow the plan and where I can push progressive overload. There is a shopping list I fill the moment I know what I need, ready for when I am standing in the store. And because I meal prep a lot, I save every meal prep with exactly what I need to make it again, pictures included.

Jarvis will never be launched, priced or marketed, and that is the point. When the only user is you, every feature can be exactly right. It is the most honest software I have ever written.
