A big exercise database is easy to dump and hard to navigate. Delts ships 845 exercises, and the real work was making them findable.
Each entry carries structured metadata: target muscle, required equipment, and difficulty level. On top of that, browsing is organized around training splits, so you're moving through the library the way you'd actually plan a week, not scrolling one giant alphabetical list.
The metadata isn't decoration. Because every exercise knows its muscles and equipment, the daily workout board can surface that context on each exercise card, and you can browse by the split that matches the equipment in front of you.
I'm a solo dev and an ACE Certified Personal Trainer, so the library reflects how a trainer categorizes movements rather than scraped tags. SwiftUI, iOS 17+, free core app, MIT-licensed and open source.
