Best one-time-purchase Mac apps in 2026

Things 3 is the gold-standard counterexample in the to-do app world. Every other major task manager (Todoist, TickTick, Notion, OmniFocus 4) has either gone subscription-only or pushed customers there. Cultured Code stuck with one-time pricing for over a decade and still ships major updates every few months.

The price stings on first download. The math gets less painful when you compare $50 once to $5 a month forever. Three years and you are already ahead. iCloud sync included. iOS and iPad apps sold separately, also one-time.

The catch: only one device family per purchase. Mac, iPhone, and iPad each cost separately.

Tot is the simplest scratchpad app on the Mac. Seven colored dots in your menu bar, each one a notepad. That is the whole product. It has been one-time since launch and the developers (Iconfactory, of Twitterrific fame) have been around since 2002 making clean indie Mac software.

The use case is the kind of thing every other app overcomplicates: drop a quick note, copy a token from an email, jot a phone number while you are on the line. Tot keeps these visible without needing a full Notes window. iCloud sync, Universal Purchase across Mac and iOS.

The catch: deliberately limited to seven notes. If you want a real second-brain app, this is not it.

A Photoshop replacement that holds up under real work. Acorn supports layers, masks, vectors, smart filters, batch processing, scripts, and PSD export. It is notarized, native Cocoa, and weighs a fraction of what Adobe ships. Gus Mueller has been building Mac graphics software since FlySketch in 2004 and is still on the same one-time license model.

For 90% of "I just need to crop this image and clean up the background" tasks, Acorn does the job better than Photoshop because there is no Creative Cloud login wall, no Genuine Software check, no reinstall after every update. Just an icon you double-click.

The catch: not an exact Photoshop clone. If you have a deep PSD-with-smart-objects pipeline, expect minor incompatibilities.

Worth listing because the team kept the one-time option after Apple bought them in late 2024. There were legitimate worries that an Apple acquisition would mean a subscription pivot. As of this writing the App Store listing still shows $49.99 once. Photo editing, retouching, ML-based upscaling, raw editing, vector tools. Best breadth-per-dollar in this class.

The Apple integration is going to keep deepening. The model itself remains a single purchase for now.

The catch: post-acquisition uncertainty. The pricing model may not survive forever.

Serif's Affinity suite is the biggest one-time-purchase counter to Adobe Creative Cloud. After Canva acquired Serif in 2024, they kept the perpetual license model and committed to it publicly. The universal license covers Designer (vectors, Illustrator class), Photo (raster, Photoshop class), and Publisher (layout, InDesign class) on Mac, iPad, and Windows.

For graphic designers and illustrators who do not need the absolute bleeding edge of Adobe AI features, Affinity is the upgrade path off Creative Cloud's $50+ a month.

The catch: file format interchange with InDesign is imperfect. Pipelines with Adobe shops have friction.

BBEdit has been shipping since 1992. Bare Bones has never put it on a subscription. Major upgrades cost about $40, but the free tier (no nag) covers most casual editing. If you grep, sed, work with logs, or maintain large plain-text projects, the paid version pays for itself in week one.

The codebase is famously stable. Version 14 on macOS Sequoia performs the same operations the same way version 8 did on Snow Leopard, but with full ARM support and modern macOS APIs underneath.

The catch: looks like a 2008 app. Not a bug if you came for the muscle memory.

Pierre Bernard runs Houdah Software as a one-developer Swiss shop. HoudahSpot is a Spotlight replacement that is dramatically more powerful than Apple's, with saved searches, complex predicates, file-content searching, and previewing. The file-finding tool that disk-archive nerds and lawyers have been quietly using for fifteen years.

One-time purchase, family pack available, occasional paid major upgrades. The exact business model that used to be the norm.

The catch: niche. If Spotlight already does what you need, this is overkill.

Soulver is a calculator that reads sentences. Type "100 USD in EUR" or "20% of $4,000" and it answers in real time. Variables and references work like a spreadsheet without the spreadsheet. One-time purchase since 2010, and Acqualia has consistently refused to subscribe-ify it.

Useful for anyone who does back-of-envelope math more than once a week. Replaces a calculator, a unit converter, and a spreadsheet for casual use.

The catch: there is a free notepad calculator built into Spotlight now. Soulver is more powerful but no longer the only option.

Hookmark is a niche productivity tool: bidirectional links between any documents on your Mac, regardless of which app they live in. Connect a Things task to a Bear note to a PDF to an email thread, jump between them with ⌘⇧H. CogSci Apps charges once for the license and offers an optional subscription for cloud sync (skip it).

For the kind of person who has 800 markdown files and a 4,000-task OmniFocus database. If you do not recognize that workflow, Hookmark is not aimed at you.

The catch: requires deep workflow buy-in. Casual users will not get value.

Shottr is the one-time-purchase counter to CleanShot X. Capture, annotate, scrolling captures, OCR, color picker, ruler. Mac-native. The license is pay-what-you-want from $8 up to your conscience. No annual fee, no cloud upload account, no telemetry.

For most people considering CleanShot's $29/year subscription, Shottr does about 95% of the same work for a one-time fee. CleanShot X alternatives roundup has the full comparison.

The catch: cloud upload is genuinely missing. If team-shared screenshots matter, CleanShot wins.

I am including my own apps because they qualify and because the catalog is built around exactly this principle. TeenyMute mutes your microphone with a Core Audio hotkey ($4.99). TeenyClip is a clipboard manager with image previews and pinned ⌘-number shortcuts ($4.99). TeenyScreeny is a live screen time counter for the menu bar ($4.99). TeenyStat shows CPU, memory pressure, and fan speed ($4.99). TeenyShelf is a drop-on-icon file shelf ($4.99). TeenyColor is a system-wide color picker with WCAG contrast ($4.99). TeenySound is per-app volume via macOS 14.2's CATaps API ($9.99). TeenyDisplay is external-monitor brightness over DDC/CI ($9.99). TeenyTool is a 75+ utility multi-tool ($14.99).

All lifetime licenses, 3-day free trial, no accounts, no telemetry beyond Sparkle update checks. Notarized, sandboxed, native Swift. The bundle is on the TeenyApps homepage.

The catch: bias. This is my product. I think it is good, but I would think that.
