Show HN: LoomLetter – an app to organize newsletters and listen on the go

Hi HN,

I love newsletters. I first started signing up for Market Briefs right after COVID—trying to figure out why everyone was so scared of another market crash. It was exciting at first, but juggling a startup meant I couldn’t keep up, and soon my inbox was a mess of unread emails. I’d often ask myself: do I read them all, or delete and start fresh?

That’s why I built LoomLetter—a simple iOS app that pulls in all your newsletter emails into one place, lets you organize them into custom lists, and even reads them aloud using AI. I built it as a one-man project to solve my own problem of newsletter overload.

What it does:

- When you sign up, you get a unique LoomLetter email address for your subscriptions.

- All issues land in the app, where you can sort them (like “Must Read” or “Tech News”).

- The standout feature for me is AI-powered narration—turning newsletters into a hands-free. I parse each email’s content and use a speech synthesis API to generate the audio. It’s not perfect yet, but I’m iterating to improve clarity for long reads.

I’m also experimenting with features ai summary (recently released) and bulk actions (wip). Currently, it’s iOS-only (built with React Native, Swift, AWS, and Supabase). I’m considering Android or even a PWA next—if there’s enough interest.

I’m facing some churn and trying to figure out what makes users stick. For instance, I’m testing a requirement for subscribing to at least two newsletters before joining. I’d love to hear your thoughts on:

- Does this solve a real problem for you?

- What might make you keep using an app like this?

- Any ideas on improving retention?

If you’re curious, you can check out the app on the App Store called "LoomLetter". Thanks for reading and for any feedback!
