Stash Deck brings your Mac controls to your iPhone. Place your iPhone beside your Mac and use four corner controls to adjust volume, brightness, appearance, keyboard backlight, audio output and more. Each corner follows the edge of the screen like a bent slider. Drag within a corner to adjust its assigned control, with optional haptic and sound feedback that makes every movement feel physical. You can also swipe left or right with two fingers to move between Mac desktops. App Profiles Stash Deck automatically changes with what you’re doing on your Mac. When you switch applications, your active Stash App Profile determines which controls appear on your iPhone, giving you different setups for different workflows. Designed around your setup * Four assignable corner controls * Automatic App Profile switching * Two-finger desktop switching * Mac-driven accent colour and appearance * Haptic and sound feedback * Direct local network connection * Explicit device approval * No account or sign-in Stash Deck is a companion app for Stash. Live control requires Stash to be running on your Mac, with both devices connected to the same local network. Don’t have Stash available? Select Preview Interface to explore the complete interface using local sample controls. Preview Interface requires no connection, account or licence. Stash Deck communicates directly with your Mac over your local network.

Verdict

The call

The clearest difference is in-app purchases: Stash Deck at none against Ampere's 1. Stash Deck also leads on ads (none vs shown) and update cadence (every 3 days vs every 3 months). Ampere's advantage is device support (3 vs 1). On price and iOS requirement there is nothing between them.
