A one-person software studio
No account, no analytics, no subscription — nothing leaves your Mac. Free for personal use, one fair fee for business.
Live Downloads and counting
We count downloads (bots excluded) on our own server. We don't keep your IP address or your location, and we never share it with anyone.
Free for personal use. A fair one-time fee for commercial use. No subscriptions, no renewal, no nonsense.
Personal: free forever. Commercial: $5 one-time per device.
See every app on your Mac that reaches the internet — and stop the ones that shouldn't. The first time an app connects, Blockr holds the connection and asks. Allow it, block it, or block just one destination. Your rules, enforced on your Mac.
Personal: free forever. Commercial: $5 one-time per device.
Universal file converter — HEIC, JPG, PNG, MP4, MOV, FLAC, MP3, Word, PDF and more, including documents to and from Markdown. Drag in, pick a format, done. Everything stays on your Mac.
Personal: free forever. Commercial: $5 one-time per device.
Download from YouTube, Vimeo, TikTok, Twitter/X, Twitch, and 1,800+ other sites — with parallel downloads, smart playlist support, duplicate detection, and automatic sponsor-segment removal.
Personal: free forever. Commercial: $5 one-time per device.
17-tool PDF toolkit that runs entirely on your Mac. Merge, split, compress, OCR, redact, protect, fill & sign, and watermark PDFs — nothing is ever uploaded.
Personal: free forever. Commercial: $5 one-time per device.
Every audio tool in one window — trim, fade, normalize, remove silence, change speed, join, and convert between M4A, MP3, WAV, FLAC, AIFF, OGG, and OPUS. Waveform editing and iPhone ringtones, entirely on your Mac.
Personal: free forever. Commercial: $5 one-time per device.
Remove image backgrounds right on your Mac with Apple's on-device Vision model — about 0.2 seconds per photo. Drop in transparency, a solid color, a blur, a gradient, or your own image, then touch up and reposition the cut-out by hand. Nothing is ever uploaded.
Personal: free forever. Commercial: $5 one-time per device.
Your Mac's vitals — CPU, memory, network, disk, battery — live in the menu bar, then answers the actual question in a sentence: "Google Chrome is using the most memory right now — 2.3 GB across 31 processes." Bring that app forward or quit it, right from the list. Everything measured on-device.
Personal: free forever. Commercial: $5 one-time per device.
One-click screen recordings saved as optimized GIFs or MP4s, straight from your menu bar. Select any area, set quality and frame rate, and get a ready-to-share clip in seconds.
Personal: free forever. Commercial: $5 one-time per device.
See what your files are secretly carrying — then strip it.
Personal: free forever. Commercial: $5 one-time per device.
Compress any video to fit a hard size limit — Discord's 10 MB, WhatsApp's 16 MB, email's 20 MB, or a custom target. Duration-aware bitrate math plus Apple hardware encoding, with the result verified to land under the limit. Nothing is ever uploaded.
Personal: free forever. Commercial: $5 one-time per device.
Drop an Original and a Revised document and Redlinr shows exactly what changed — deletions struck through in rose, insertions underlined in green — with an aligned split view and a plain-English summary. Nothing is ever uploaded.
Personal: free forever. Commercial: $5 one-time per device.
Why is this file so big? An X-ray of what's eating the bytes — down to a treemap of a whole folder.
Personal: free forever. Commercial: $5 one-time per device.
Rename hundreds of files at once, safely. Stack rules — find & replace, numbering, dates from EXIF, case, cleanup — and watch a live Current → New preview with every changed character highlighted. Name collisions are refused before a single file is touched, and every batch is undoable with ⌘Z.
Personal: free forever. Commercial: $5 one-time per device.
Keeps your Mac awake for exactly as long as you say — no idle sleep, no display sleep, no screen saver. Lives quietly in the menu bar with duration presets from 15 minutes to indefinite, using the same power-management assertions as caffeinate.
Personal: free forever. Commercial: $5 one-time per device.
Turn a folder of stills into a smooth looping GIF. Set per-frame timing, preview it live, and export clean — no watermark, no upload, all on your Mac.
Personal: free forever. Commercial: $5 one-time per device.
See exactly what's eating your disk. Point Diskr at any folder and it maps every file into an interactive sunburst — drill into the biggest slices and move space hogs to the Trash, all on your Mac.
Personal: free forever. Commercial: $5 one-time per device.
The file copier Finder should have. One unreadable file costs you a line in the report, not the rest of the job — and if you unplug the drive mid-copy, Copyr waits for it and picks up where it left off.
Personal: free forever. Commercial: $5 one-time per device.
Ctrl+C copies. Ctrl+S saves. Alt+Tab switches. Thirty years of Windows muscle memory, working on your Mac — rewritten in an event tap before the app in front of you sees the key. No kernel extension, no driver, no restart. Terminals ship excluded, so Ctrl+C still interrupts.
Personal: free forever. Commercial: $5 one-time per device.
Swipe away a 2FA code by reflex and macOS keeps no record of it. Pingr copies every notification into a durable, searchable archive on your Mac before macOS throws it away — and puts a copy button on any one-time code it finds.
Personal: free forever. Commercial: $5 one-time per device.
Snap the focused window to a half, third, quarter or sixth from the keyboard — press the same direction again to cycle sizes. Drag to a screen edge for a live preview of where it will land. Save a layout once and it restores itself the moment you dock or undock.
Personal: free forever. Commercial: $5 one-time per device.
Holds your audio devices where you put them. A monitor can't take your sound and AirPods can't take your microphone — output, mic and system sounds are held separately, which is the one thing the Sound settings pane can't do. Needs no permissions at all.
Personal: free forever. Commercial: $5 one-time per device.
Sweeps the mess out of your Downloads folder. It sorts what it finds into obvious piles and shows you the entire plan before a single file moves — then one click sweeps it and one click puts it all back. It has no delete code path at all: it only ever moves files, and every sweep is journaled to disk before it starts.
All free for personal use. Everything's checked — uncheck anything you don't want.
