Add-ons for Google Workspace™.
Apps for Android.

Codoha is a small software company in Hualien, Taiwan. We make add-ons that work inside Google Sheets™, Docs™ and Slides™, and Android apps for learning and daily life, published on Google Play™.

About Codoha

What we build

On the desk, our add-ons install from the Google Workspace Marketplace™ and work inside the documents your team already uses: schedules written into Sheets™, tables built in Docs™, API data pulled into a spreadsheet. On the phone, each app does one job: practising Chinese, reading Japanese kana, keeping your own rules in front of you, or working an air traffic control shift by voice. Every app states in its own privacy policy what leaves the device. Two of them never connect at all.

Products

Our products

Add-ons that run inside Google Workspace™, and apps that run on Android.

Google Workspace™ Add-ons

Installed from the Google Workspace Marketplace™ and used inside Sheets™, Docs™ and Slides™.

API Import for Google Sheets™

Live API data in Google Sheets™

Pull data from Shopify, HubSpot, the YouTube Data API™ and any REST endpoint into Google Sheets™ by describing the request in plain English. Save the request as a workflow and schedule it to refresh on its own.

Text To Table Converter

Tables and document tools for Docs™, Sheets™ and Slides™

Paste unstructured text and get an editable table inside Google Docs™, Sheets™ or Slides™. The same sidebar holds PDF merge, split and OCR, an AI writing assistant, a chart wizard and a set of one-click document utilities.

AI Shift Planner

Shift and class schedules from written instructions

Describe the shifts, the people, their availability and your rules in plain text. AI Shift Planner writes a conflict-free schedule into Google Sheets™ and spreads the load evenly across the team.

Android Apps

Installed from Google Play™. Each app has its own page and its own privacy policy.

TingWo

Chinese practice from your own texts

Paste or photograph any Chinese text and TingWo turns it into a vocabulary trainer built around speaking: new words chosen for your HSK level, recorded native audio, pinyin or zhuyin, tone practice and spaced review.

Habit Armor

Reminders of your own rules

A free Android app that works without a connection. Write a rule and the reason behind it, and Habit Armor shows the card as a notification a few times a week at random, or at the weekly times you set. No account, no ads, no tracking.

Himari

Japanese kana, taught without English

An Android course for hiragana and katakana that never shows a translation. Each word arrives as a drawing, a voice and the kana themselves, inside an illustrated story. Works offline, with no account and no tracking. On Google Play™.

ATC Simulator: Voice Control

An ATC game you play by voice

An Android air traffic control game played by voice. Work the tower cab or the approach radar: give real clearances, hear the pilots read them back, and learn the phraseology from the FAA manual built into the app. Free to start on Google Play™.

How we work

Each product is designed, built and supported by the same small team, so a support email reaches someone who knows the code. The add-ons pass Google’s review before they are listed on the Google Workspace Marketplace™, and the apps pass Google Play™ review. Every app asks for the permissions its job needs and no others, and the apps that need no connection do not request one.

  • Reviewed by Google before listing on the Marketplace™ and on Google Play™
  • Runs inside Google Workspace™ and on Android
