Everything your trackpad can do.
Ten actions you can wire to any edge, plus the engineering details that make them feel invisible.
Four edges. Whatever you want.
Assign each edge independently. Mix and match. Change your mind tomorrow. fadr remembers the combinations that work for you. The full vocabulary:
- 01 System volume LEVEL Swipe to set the output level with the native Tahoe volume HUD. Snap to mute at the bottom, max at the top.
- 02 Display brightness LEVEL Adjust the built-in display without reaching for F1 or F2. Uses the same media-key path as your keyboard buttons.
- 03 Keyboard backlight LEVEL Perfect illumination in every room. Tweak without breaking your typing rhythm.
- 04 Microphone volume LEVEL Raise input on a noisy street. Drop it before a breath. Visible feedback, no guesswork.
- 05 Media scrub SCRUB Swipe smoothly through the current track's timeline. Works in Music, Podcasts, Spotify, and Safari.
- 06 Media skip SWIPE Swipe past center to jump tracks. Discrete next / previous, just like the keyboard media keys, without the reach.
- 07 Color temperature LEVEL Night Shift on a slider. Warm your display when you need it, cool it when you don't.
- 08 App zoom LEVEL Precision zoom in Figma, Xcode, Finder, Preview, or any app that responds to pinch-to-zoom. The edge becomes a zoom slider.
- 09 Spaces navigation SWIPE Glide between desktops and full-screen apps with a single edge swipe. Direction-aware.
- 10 Custom shortcut CUSTOM Map an edge to a safe key combination of your choice. fadr blocks destructive or conflicting combos (no raw F-keys, no Help, no system hotkeys) so you don't accidentally shoot yourself in the foot.
Small details. Big difference.
The gesture is the easy part. Making it feel invisible is where fadr spends most of its engineering budget. Seventeen decisions that disappear into your hands.
- 01
Per-app profiles
Let Xcode have zoom on the left edge. Let Logic have media scrub. fadr knows what you're doing and adapts.
- 02
Velocity-aware sensitivity
Swipe slowly for fine control. Flick fast for big jumps. The curve follows your intent, not a fixed ratio.
- 03
Two-finger coarse mode
Drop a second finger to multiply step size. Cover the full range without crossing the whole pad.
- 04
Mute and max snap
The ends of the slider lock in with a small haptic tick, so you always land on zero or one hundred.
- 05
Edge lock
Once a swipe starts, fadr won't jump to another edge. No accidental mid-gesture swaps.
- 06
Typing detection
Rests while you type. Wakes the moment you stop. Zero accidental volume dips while drafting an email.
- 07
Modifier key gating
Require Option or Control to activate. Perfect for Mac users who use the edges for scrolling.
- 08
Cursor freeze
While you're adjusting, the pointer stays exactly where you left it. Your workflow never resets.
- 09
Native macOS HUD
Uses the real system volume and brightness indicators. Indistinguishable from Apple's own controls.
- 10
Shortcuts support
Two App Intents ship today: "Toggle fadr" to arm or disarm gestures, and "Switch profile" to swap saved profiles. Works from Shortcuts.app, Siri, and keyboard shortcuts.
- 11
Focus Filter
A SetFocusFilterIntent lets you pin a specific profile to a Focus — Do Not Disturb, Personal, Work, or any custom Focus you set up — so gestures follow your context.
- 12
Zero-config defaults
Volume on the left, keyboard light on top, brightness on the right, media skip on the bottom. Ten seconds after install, you're sliding.
- 13
Haptic detents
Every step clicks back with a micro-tap through the Force Touch engine. Choose Light, Medium, or Strong in Settings to match your taste.
- 14
Whole-pad mode
Hold a modifier combo you pick — Control-Option by default, but any subset of Shift, Control, Option, Command, and Fn works — and a swipe anywhere on the pad drives two actions: one horizontal, one vertical. The cursor freezes automatically while the combo is held.
- 15
Three-finger middle click
Tap anywhere with three fingers to middle-click — open links in a new tab, close browser tabs, anything middle-click does. Opt-in in Preferences.
- 16
Double-tap shortcuts
Every edge has a double-tap action that fits what it controls. Double-tap the volume edge to mute, or the mic edge to kill input. Double-tap color temperature to toggle Night Shift. Double-tap a custom shortcut edge to fire your keybinding.
- 17
VoiceOver ready
Accessibility-first. Opt in and fadr will speak every value change using the same VoiceOver voice the rest of macOS uses.
Ready in thirty seconds.
No setup wizard, no questionnaire, no sign-up. Install, permit, swipe. Three steps, one dialog box each.
- 01
Download
A single .dmg, notarized by Apple. Drag fadr to Applications. Under three megabytes.
- 02
Grant permissions
Two one-time permissions in System Settings — Accessibility so fadr can read trackpad gestures, and Input Monitoring so it can step aside while you type. Onboarding walks you through both.
- 03
Swipe
That's it. Your trackpad has new controls. Open Preferences any time to reassign an edge.
Questions people ask.
Still curious? Write in. The developer answers personally, usually the same day.
01 What does fadr need permission for?
Two macOS permissions, both one-time: Accessibility (so fadr can read trackpad gestures) and Input Monitoring (so fadr can notice when you're typing and when a modifier key is held, which powers the typing-detection and modifier-gate safety filters). Onboarding walks you through both. fadr doesn't ask for Full Disk Access, Contacts, Location, Camera, or any other macOS permission. Network-wise, it only makes two kinds of requests: a once-per-day update check (a single fetch of a static release manifest from updates.fadr.app) and license validation with Lemon Squeezy when you activate a key or during the weekly background re-check. No analytics, no telemetry, no crash reports, no usage tracking.
02 Does fadr collect any data?
No. Zero telemetry, zero analytics, zero crash reports sent home, zero anonymous usage stats. Your settings and profiles live in a standard .plist on your Mac and never leave it. If fadr ever changes this, the change will require an explicit opt-in and will be documented in the release notes.
03 Will it work with my Magic Trackpad?
Yes. fadr supports the built-in trackpad on every MacBook with Force Touch (2015 onward) and the external Magic Trackpad 2 or newer. If you have both connected at the same time, fadr listens to both and applies the same edge assignments to each.
04 What if I don't like it?
The 14-day trial is fully functional and requires no credit card. If fadr isn't for you, just delete the app — you were never charged. If you buy and change your mind later, email us within 30 days for a refund.
05 How do I uninstall?
Drag fadr from Applications to the Trash. That's it. You may also want to revoke its Accessibility and Input Monitoring permissions in System Settings if you want a clean removal.
06 Does it play well with BetterTouchTool?
Yes. fadr only watches the trackpad edges, and BTT mostly cares about the middle of the pad. If you do have a conflict, fadr's edge lock setting is tunable, and BTT can be told to ignore edge regions. We have a short integration guide in Support.
07 Why isn't fadr on the Mac App Store?
The App Store sandbox forbids the level of trackpad access fadr needs to work. Rather than strip out what makes the app useful, we distribute directly, with Apple notarization for security.
08 Can I use one license on multiple Macs?
Yes. Your $3.99 license covers up to two personal Macs that belong to you — your work laptop and your personal laptop, or your desktop and your MacBook. Lemon Squeezy tracks the activations so we don't have to run our own account server. If you need to move the license off an old Mac, there's a Deactivate button in the License window.
Swipe. Don't reach.
Try it free for 14 days. Keep it forever for $3.99. If it doesn't earn permanent trackpad real estate, drag it to the trash and we part as friends.
