Productivity Apps for Mac, One-Time Purchase

By NUR Technologies · October 30, 2026 · 4 min read

Getting work done on a Mac does not require a monthly fee. Some productivity tools are bought once and stay useful for years. These NUR apps help you focus, organize PDFs and convert files, each with a single price.

Focus: Pomorito

Pomorito is a pomodoro timer with a tomato that drains as time runs out. You write one task per pomodoro, it blocks the apps and sites that distract you (in Chrome, Safari, Brave, Edge, Arc and Vivaldi), and it shows how much you focused by task, project and hour. It costs $5 and needs no account.

Documents: Rivet

Rivet gathers everything you do with PDFs in one app: merge, split, compress, sign, fill, truly redact and OCR. It costs $10, and your files never leave your Mac.

Files: Simple Archive Converter

Simple Archive Converter converts images, documents, audio, video and more in bulk. It costs $5, and everything runs on your Mac.

How to choose a one-time purchase app

• Confirm the one-time price on the page before you buy.
• Try the part you use most. Most daily tasks come down to one or two functions.
• Check whether updates are included in your purchase.
