Eleven free apps for Mac and Chrome
Working with AI, planning and mail, transcribing recordings, switching audio devices, resting your eyes, finding your pointer, translating text, clocking in on time. K386 is an independent developer who builds these apps for daily work and shares them for free. Start from a problem you have, and look closely before you download.
The apps and their guides are in Japanese (ClauDeck can also switch to English).
Hi, I'm Hana, your guide. Starting from "what's bothering me" is the quickest way to find the right app.
Pick the one that fits and you'll jump to that app.

I want to translate an email or document right where I'm reading it
Honyaku
I keep forgetting to clock in and out on jinjer (a Japanese attendance service)
Auto打刻アシスタント
Each card shows the macOS version it needs and when it goes online. Open a card for screenshots, a how-to, and everything worth checking before you download.
The small tags under each card make it easy to compare Mac support and network use.
A key lights up when an approval is waiting.
Answer AI approvals with a physical key.
Shows the state of Claude Code, Codex and Antigravity on the keys of an Elgato Stream Deck. When an approval is needed, press a key to approve or cancel without switching windows.
For: people who let AI write code and keep switching windows to approve it
I'll show your remaining quota on a meter.
Your AI quota, right on the desktop.
Shows the remaining usage quota of Codex, Claude and Antigravity, and when it resets, in a desktop widget. No more opening a browser to check.
For: people who have hit an AI usage limit in the middle of work
We're getting it ready. Please check back soon.
Plan your day, on this Mac.
Brings tasks, schedule, notes and daily reports into one window. An AI assistant helps organize the morning and drafts the daily report at the end of the day. You choose where the AI runs: on this Mac or in the cloud.
For: people who want morning planning and daily reports done faster
Work and personal, side by side and never mixed.
All your Google accounts in one place.
Opens Gmail, Calendar, Keep and Contacts for each account side by side, kept separate. Less signing in and out, and less risk of sending from the wrong account.
For: people who keep switching between work and personal Google accounts
Recordings become text you can search later.
Turn recorder audio into records you can find.
Connect an IC recorder and icRec imports its recordings. It also manages iPhone Voice Memos and recordings made on your Mac, and keeps transcripts, summaries and to-dos with each recording. With Apple Intelligence, AI features are free and stay on your Mac.
For: people with a pile of meeting or memo recordings that are hard to replay
Your audio never leaves this Mac.
Turn speech into text, right on your Mac.
Drop in audio or video and it is transcribed on this Mac. Live transcription from the microphone and subtitle export (SRT, VTT and more) are included. No API key needed.
For: recordings that must not leave your company, or subtitles for videos
Switch where the sound goes with one key.
Change the sound output with one keystroke.
Puts speaker, headphone and microphone switching and volume control into one menu bar icon. Pin the devices you use and cycle through them with a keyboard shortcut.
For: people who reselect the microphone or speaker before every call
Every 20 minutes, I'll remind you to rest your eyes.
A short eye break every 20 minutes.
A timer that makes the 20-20-20 habit easy to keep: after 20 minutes of work, look at something far away for 20 seconds. The menu bar icon shows the time left, and a full-screen overlay tells you when to rest.
For: people who look at screens for long stretches and forget to take breaks
A glowing ring shows where your pointer is.
Never lose your pointer.
Draws a glowing ring around your mouse pointer and a small ripple where you click. Change the color, size and opacity from the menu bar; clicks and drags pass straight through.
For: people who lose the pointer on large displays, multiple monitors or screen shares
Select text and press ⌥⇧T. The translation appears in a small window.
Translate what you select, in place.
Translates text you select in other apps with ⌥⇧T, or by dragging it onto a drop area. For text in images or subtitles, hold F1 and draw a box around it. Copy the result or replace the original text. Translation and text recognition run on your Mac; no API key needed. New versions install automatically.
For: people who want to check English mail or documents quickly, or send what they wrote in another language
Set a morning and an evening time, and it clocks in and out for you.
Clock in and out on schedule.
Clocks in and out of jinjer, a Japanese attendance service, at the morning and evening times you set. Skips weekends, Japanese holidays and planned days off, and can clock in on a chosen day off. Your login stays inside Chrome.
For: jinjer users who forget to clock in, or want it done at a steady time
Whether it runs on your Mac, when it goes online, and what else you need. Auto打刻アシスタント is a Chrome extension rather than a Mac app.

Rather than just saying "safe", we explain what we do and how you can check it yourself.
Every released Mac app is shipped as a DMG signed with a Developer ID and notarized by Apple (the Chrome extension, Auto打刻アシスタント, is published on the Chrome Web Store after Google's review). The notarization ticket is stapled to the file, so it can be checked even on a Mac without internet access.
Notarization is Apple's automated check for known malware. It does not guarantee the app's quality or behavior.
You can confirm a download is the official file in Terminal. Each app's download page lists the file's SHA-256, a kind of fingerprint.
spctl -a -vv -t open --context context:primary-signature ~/Downloads/FILE.dmg shasum -a 256 ~/Downloads/FILE.dmg
The first line should print "accepted" and "Notarized Developer ID". If the second line's value matches the SHA-256 on the download page, the file has not been altered.
What you create and your settings are stored on your Mac. The apps send no usage telemetry. Every case where an app goes online, such as update checks or integrations you turn on, is listed in "Network and data" on its page.
This website only counts page views and downloads. IP addresses are not stored.
The apps are not hosted on other sites or mirrors. If you find a file with the same name elsewhere, don't open it; download it from this site instead.
They are free because they were built for the developer's own work and are shared so other Mac users can use them too. There are no ads and no upsells.
HanaThe same check steps are on every app's download page, too.
Longer pieces about how the apps are used and how they were built. The articles are in Japanese; new ones are added here as they are published.
For people who use the apps: a real problem, the steps to solve it, and screenshots.

K386 is an independent macOS developer in Japan. Each app started as "I wish I had a tool for this" during daily work, was built for that work first, and is still used and improved every day. They are shared for free because they seemed too useful to keep to myself.
The apps and their guides are written in Japanese. ClauDeck can also be switched to English.
