Ditch the expensive corporate bloat. Meet the minimalist workspace designed exclusively for solo freelancers.
Right now, you probably use one app for email, another for task tracking, another for file sharing, and an accounting tool just to send a simple invoice. You're spending more time managing your work than actually doing it.
From the first client email to getting paid, in one seamless environment.
Connect your inbox and turn chaos into clarity. AI summarizes long emails into a single sentence so you can instantly delete the noise. Reply or seamlessly turn requests into tasks directly to active projects.
Most project tools look like an airplane cockpit. We ditched the complex Gantt charts for a clean, drag-and-drop board. The tasks land right here. Do the work, check the box, and queue it up for billing.
Look like a top-tier agency. Share a secure workspace where clients can track progress, download deliverables, and upload their own files. Fully customized with your own brand.
Done with the project? Stop doing double data entry. Turn your completed tasks and hourly rates into a beautiful PDF invoice in seconds. Generate, send, and get paid faster or export to your accounting software instantly.
Just add a prospect's website. Our built-in AI automatically extracts their business information, finds key contacts, and drafts a highly personalized outreach email for you.
Your data is physically yours. We use isolated workspaces and encrypted API keys. We can't see your client files or emails even if we try. Total privacy, zero compromises.
We don't charge you extra for AI. Bring your own API key (OpenAI/Anthropic/Gemini/Perplexity). You pay them directly only for what you use (usually pennies). No artificial limits, no hidden SaaS markups.
Your dedicated workspace comes in 21 languages (and counting). Work in your preferred UI, and impress your clients with invoices and client workspaces fully translated into their native language.
We hate complex pricing tiers as much as you do.
Stop paying multiple subscriptions.
We will send you a friendly email. If you love UseOneApp, you pay the $99 yearly fee. If it's not for you, we simply delete your private workspace. No automatic charges.
Absolutely. Unlike massive SaaS tools where everyone shares one giant database, your data is stored in a private, flat-file architecture completely isolated from other users.
I am an independent developer building tools for people like us. If you have a feature request that aligns with our minimalist philosophy, shoot me an email! Many of our best features come from user feedback.
Hi, I'm Pavel. Like most freelancers, I was drowning in browser tabs and chaotic workflows. I was spending more energy organizing the mess than actually creating anything.
So, I built the tool I desperately needed.
UseOneApp is a pure, minimalist workspace that connects your entire day. No corporate bloat. No limits on AI. Just one simple tool designed for how solo creators actually work.
