Show HN: Axletic – a local-first workout tracker for iPhone

Hi HN,

I built Axletic, a native iPhone workout tracker focused on making workout logging feel quick and uncomplicated. I drew a lot of inspiration from clean, dark themed apps such as Linear. I felt like a lot of fitness apps out there were too complicated to get started with, messy UI, too many settings etc.

This one is made for people that just want to log what they do and understand how it is going. Kinda like a notes app for workout tracking.

The core idea is that recording a workout should not interrupt the workout. Axletic lets you log weight, reps, duration, distance, rest periods, and personal notes while keeping the interface deliberately minimal.

Beyond logging, it can:

- Visualize which muscle groups a workout targeted - Compare an exercise with a previous session or your historical average - Show long-term trends across different training metrics - Search a library of 800+ exercises with photos and instructions - Run rest timers through notifications and Live Activities - Store workout data locally, with optional iCloud sync and backup export/import

The app is built natively with SwiftUI, SwiftData, Swift Charts, and ActivityKit. Protecting workout history and keeping the data model reliable have been important parts of the project.

I would be super happy if you take a look and leave some feedback. I am happy to answer questions too. This is an early v1, so not perfect, but also not too bad.

I have been "living on the edge" with this one for a few months to try and find the right affordances in the UI. Searching for simplicity. 3 times a week I was the user, and wrote myself feedback on things to improve. Please let me know you what you think. I have many ideas for how to evolve this.

Thanks a bunch!
