Most "best Mac apps" lists are full of $50/year subscriptions. I get it — recurring revenue is the business model du jour. But as a developer who pays for my own tools, I've found that the best stuff is often shockingly cheap.
Here are 7 Mac apps I use daily, all under $20, that have genuinely improved how I work.
1. Raycast (Free)
If you're still using Spotlight, stop. Raycast is a launcher on steroids — clipboard history, snippet expansion, window management, and a growing extension ecosystem. The free tier covers 95% of what you need. I launch apps, convert units, search docs, and manage windows all from one shortcut. It replaced three separate apps for me.
2. Rectangle (Free)
Before you say "Raycast does window management" — sure, but Rectangle does it better if you want dedicated keyboard shortcuts without thinking about it. It's open-source, weighs almost nothing, and just works. Snap windows to halves, thirds, or quarters with muscle-memory shortcuts. I've tried Magnet, Moom, and others. Rectangle wins on simplicity.
3. Numi ($20 — Lifetime)
A calculator that lives in a text editor. Type natural language like "$3.50 * 1200 requests" or "25% of $480" and get instant results. Perfect for back-of-napkin API cost estimates. I keep a Numi window open all day for quick math during sprint planning and cost projections.

4. TokenBar ($5 — Lifetime)
If you work with LLM APIs at all — ChatGPT, Claude, Gemini, local models — this one's a no-brainer. TokenBar sits in your menu bar and tracks token usage across providers in real time. I used to get blindsided by API bills at the end of the month. Now I glance up and know exactly where I stand. Five bucks, one-time. Pays for itself after catching one runaway API call.
5. Hand Mirror (Free)
A menu bar app that shows your webcam feed with one click. Sounds trivial until you realize you've been on three Zoom calls with bedhead. It's the "check yourself before the meeting starts" app. Zero config, zero CPU usage when idle, exactly one job done perfectly.
6. Monk Mode ($15 — Lifetime)
Most focus apps block entire websites. Monk Mode blocks at the feed level — so you can still use Twitter for DMs or YouTube for tutorials, but the infinite scroll disappears. This distinction matters. I don't need to block Reddit entirely; I need to block the front page that sucks me in for 40 minutes. Monk Mode gets that nuance right.
7. CleanShot X ($8 — One-Time via Setapp / $29 standalone)
The best screenshot tool on Mac, period. Scrolling capture, annotation, cloud upload, screen recording, OCR — it does everything the built-in screenshot tool wishes it could. I use the scrolling capture daily for bug reports and the annotation tools for async code reviews. Worth every penny at any price point.
The Common Thread
Every app on this list is:
- Native macOS — no Electron, no web wrapper
- Under $20 (most are free or one-time purchases)
- Does one thing well instead of trying to be a platform
The subscription fatigue is real. These tools prove you don't need to rent your workflow. You can own it.
