Lyra's first paying customer uninstalled my app after one hour. I spent a month discovering why. Keep talking to your users.
6 months ago I left a decade of fintech engineering in London to build Lyra solo ,a Mac writing assistant that fixes your writing as you type, in every app.
The problem I built it for: everyone I worked with had the same ritual. Type a message, re-read it four times, paste it into some tool, fix it, paste it back, tweak the tone, send. Multiply by 50 messages a day. And the tools that "help" all have the same flaws — they live in a separate window, they interrupt you with underlines while you're mid-thought, and they sand everyone down to the same polished-robot voice, whether you're messaging your boss or your best mate.
So Lyra works differently: you just type. Pause, and a small pill shows a better version — press Tab, done. No panel, no copy-paste, no clicks. It works in Gmail, Outlook, Slack, WhatsApp, your browser, wherever you write. And it learns how you write to each specific person, so your message to a client and your message to a friend don't come out sounding like the same press release.
Launched quietly in July. Show HN flagged my post. Reddit: silence. X: silence. Then one person paid ,a guy in France. I was thrilled for about an hour, which is how long it took him to uninstall: Lyra was freezing his Mac every minute.
Here's what that month taught me. I assumed the worst (memory leak), built instrumentation, ran controlled tests on identical hardware and my confident assumption was wrong. The real cause was a design decision I'd shipped without questioning. Fixed it, the freezing died, and he told me he'd reinstall ,he'd called Lyra "a really great product" while uninstalling it, which is the strangest compliment I've ever received.
Since then: fixed the biggest issues my ~30 early users hit, rebuilt the rough edges, made a proper demo. Relaunching today.
Mac only. 14-day full trial, free tier after, $9.99/mo for Pro.
Happy to answer anything , the debugging saga, why the first launch flopped, what one uninstall taught me that 30 signups didn't, or the unglamorous reality of marketing as a solo dev.
