Trailer Park

Live on the App Store

Movie discovery that feels like opening night.

A native iOS app for finding movies, watching trailers, and tracking what you've seen, with watch-together built in. A real-time Convex backend and TMDB metadata turn "what should we watch?" into the best part of the evening.

  1. Trailer-first discovery with curated collections
  2. Watch history and personal ratings that sync in real time
  3. Watch-together sessions across devices

Speek

Open source

Dictation that never leaves your Mac.

Fully local speech-to-text for macOS. Hold a hotkey, talk, release. Speek transcribes with Parakeet TDT v2 on the Apple Neural Engine, formats with a hybrid of regex and Apple Foundation Models, and types into whatever app you're in. No cloud, and no audio ever leaves the machine.

  1. Push-to-talk hotkey that transcribes in place, in any app
  2. On-device Parakeet TDT v2 on the Neural Engine
  3. Smart formatting with Apple Foundation Models plus regex

VideoPro

Open source

Grab the video. Keep the quality.

A Chrome extension and a Mac app that work as a pair. The extension spots playable video on the page you're viewing; the Mac app handles fast, reliable downloads in original quality. One click in the browser, a file on disk.

  1. Chrome MV3 extension with in-page video detection
  2. Native macOS companion for downloads and the queue
  3. Original-resolution output, no re-encoding

Mac Vitals

New · Open source

Is your Mac okay? One number tells you.

A system monitor and cleaner built in SwiftUI and Liquid Glass. It rolls CPU, memory, disk, battery, and thermals into a single health score. The menu bar panel answers one question: is anything wrong, and what's the one fix? The main window is for digging in, and every cleanup is reviewed before anything is deleted.

  1. One health score, with a vital-signs checklist showing what feeds it
  2. Live CPU, memory, disk, network, and battery history; frozen-app detection
  3. Smart Clean, Space Lens, duplicate and similar-photo finder, and an uninstaller
  4. Dev Servers: every listening port on your Mac and the process behind it
  5. Update checks across Sparkle, the App Store, and Homebrew

The studio

Simmons Development is the independent studio of Tyler Simmons. Every product here is designed, engineered, and shipped in-house, from SwiftUI front ends and Chrome extensions to real-time back ends and on-device ML.

01

Native first

Apps that feel like they came with the platform: the right controls, the right shortcuts, the right weight.

02

Performance is a feature

Measured, not assumed. Mac Vitals idles at 0.2% of a core, and Speek never sends a second of audio off the machine.

03

Actually finished

Signed, notarized, self-updating, and documented. The bar is shipped, not demoed.
