For those still in need for a personal resolution... Personal statistics aggregator Daytum, originally conceived by 'personal-year-report-designer' Nicholas Felton and Ryan Case, has just released a dedicated iPhone app [daytum.com, direct iTunes link] to make tracking your daily activities that much simpler and easier.
The app allows creating, tracking and exploring individual categories (e.g. to capture your weight to when, how much, and what brand you choose when you drink coffee), while also offering some nice interactive line graphs to get an overview of any historical trends.
While the app itself is free, Daytum itself offers both a free account, and a $4/month "unlimited" account for those who wish to have access to additional features including the ability to collect and present more data, create pages and apply privacy settings to their account.
How does it compare to other self-tracking iPhone apps, out there?
