Niche-Knack — Smart Tools. Sharp Solutions.

I'm one engineer in Ohio. I make apps for narrow needs, and I don't call one done when it works; it has to be a pleasure to use. Pocket Nerd catches the daily spending. LedgerKeep keeps the books. Clip Dr. works on the sound. Rabbit Trail follows the evidence. Choirboy lets you choose what gets filtered in your media. Euphonics gives your poems and lyrics room to grow.

I’m looking for beta testers. Find one you’d like to test.

Money

Pocket Nerd

Open. Enter. Done.

A scratchpad for money, in your pocket. Write down what you spent in seconds, see what it does to tomorrow, and change your mind as often as you like. Nothing is wired to a bank. Four themes — and a game to break a tie when you can't decide.

Double-entry books in plain-text Ledger files, with Git history, bill reminders and debts you can fight as bosses. Keep the books on your phone; spread out on desktop for reconciliation, budgets and reports.

Sound and research

Clip Dr.

Find the moment. Fix the sound.

Turn a long recording into useful clips. Find the passage, make the edit, and keep a library with every version preserved. Local transcription and focused sound repair are there when you need them.

Rabbit Trail

Follow the clues. Keep the source.

An evidence board and research archive. Collect documents, scans, notes and recordings; follow names, dates and relationships back to the passages they came from. Capture on Android and investigate on desktop.

Media and writing

Choirboy

It’s your media. Enjoy it your way.

Choose what gets filtered in media you own or legitimately access. Bring music and video from Plex, Emby, Jellyfin and more. Discover podcasts, read transcripts and keep a listener’s backup of a live show.

Euphonics

Find your rhyme. Keep your voice.

Find the right rhyme, try a near rhyme, and give a few words room to grow. A writing space for poems, verses, and the chorus you can’t get out of your head.

How this works

These apps don't try to be everything to everyone. Each one does its job very well and stays out of the way. Design is part of the job, not a coat of paint on top.

Local files and useful tools come first. Each product page explains the app’s platforms, how it handles data and what is available now. Choose an app and request a place in its beta. I review the requests and email approved testers a private download link.
