I'm a software engineer with 25 years of experience, and this started as something I built for myself. I originally wanted to track energy and didn’t find something in the App Store that fit what I had in mind. I prototyped the first version in Rork, which got me moving fast, then migrated to Xcode when I needed more control over proprietary extensions.I’ve been using it daily for several months while I add features and rearrange things. I’m just starting to promote it now.
The main screen shows your whole week at a glance as a color grid, so you can spot patterns without navigating through multiple screens. Data stays private on your device and backs up to your personal iCloud. No sign-in, no shared database. All of the important features are free and there are no ads. There is a subscription for some extra features.
Feedback and bug reports welcome! I’m hoping some others will find it as useful as I do. https://apps.apple.com/us/app/trilog/id6754526159
