How a desperate paralegal, a freelance developer's janky Google Sheet, and one stubborn "there has to be a better way" moment became AetherTime.
AetherTime is a local-first desktop app for people who bill by the hour. No cloud, no monthly fees, no IT approval needed — just a portable executable on a USB drive that gives you task management, time tracking, invoicing, and analytics in one place.
I've been a programmer for long enough to know that most problems don't need a new app. They need discipline, a process, maybe a better spreadsheet.
For years, I freelanced alongside my day job — consulting gigs, side projects, the occasional "can you build a WordPress site" for a friend. I tracked everything in a Google Sheet. Columns for client, project, date, hours, rate, total. It worked. Barely.
Then I had a month with four clients and twelve projects, and the sheet fell apart. Wrong totals. Double-counted hours. A color-coding system that only I understood. I kept telling myself I'd find a proper tool — but every option was either a monthly subscription or required an internet connection. Neither made sense for something I used twenty minutes a day.
So I did what any programmer does when the tools don't fit: I started building my own.
Six months ago, my wife took a paralegal position at a small but growing law firm.
The caseload was climbing. The firm was understaffed. And her day was a constant negotiation between getting work done and documenting every six-minute increment of it. Billable hours are the oxygen of a small firm — but nobody gives you more hours in the day to track them.
She needed software. The firm needed software. But IT had the machines locked down tighter than a discovery deadline. No installs. No admin rights. The approved solution? A shared spreadsheet on the network drive.
She was back in spreadsheet hell. Different column names, same broken system.
I looked for something that would work on a locked-down machine. Every option was cloud-based, required admin access, or cost more per month than the firm was willing to spend on a paralegal's time tracker.
So I opened my own half-finished time tracker — the one I'd been building between freelance gigs — and I pivoted hard.
The constraint became the design: it must run from a USB drive with zero installation. No registry keys. No system folders. No admin rights. Plug it in, double-click, done.
I rebuilt everything around that one requirement. The timer. The task hierarchy. The billing engine. PDF invoices she could email straight to clients. Dark mode because she works late, and late at night you don't want a white screen screaming at you.
I shipped her the first build on a rainy Tuesday. She emailed me the next morning: "Other paralegals saw it. Can they get copies?"
That first USB drive turned into five. Then ten. The lawyers wanted it too. Then a freelance consultant who'd been watching me build it asked for a copy. Then his freelancer friends.
I kept adding what they asked for:
Every feature came from a real conversation with someone who bills by the hour. No VCs. No product roadmap by committee. No quarterly OKRs. Just a list of problems that needed solving, built one at a time.
Your data is yours. AetherTime stores everything on your machine. We don't have access to it, we don't want access to it, and we built nothing that could exfiltrate it. The app doesn't even phone home.
Software should fit in your pocket. Portable. Offline-capable. Run it from a USB drive, a cloud folder, or your desktop — it's the same single executable either way.
You shouldn't rent a tool you use twenty minutes a day. One payment. No subscriptions. No surprise price hikes. No "we've redesigned the billing experience" emails.
Small firms and solo pros deserve better. Enterprise software is built for enterprises — it costs like one, too. AetherTime is built for the paralegal drowning in a caseload, the freelancer juggling four clients, the consultant who just wants to start a timer and know the invoice will be right.
AetherTime is just getting started. I still build it the same way I started — one feature at a time, driven by conversations with people who actually use it. If something's broken, the fix ships fast. If something's missing, I want to hear about it.
This is a desktop app in a cloud-software world. I know that's not fashionable. But I think there's a market for software that respects your privacy, your wallet, and your need to get work done without paying rent on a timer.
