Focused Android apps, built with Claude.

Apps we have shipped

Six of the 20+ apps we publish on Google Play. Every one is live and maintained.

1. 

   Food Scanner

   Food Scanner: Calorie & Label

   Snap a meal, a nutrition label or a barcode and see the calories, nutrients, ingredients and allergens in your own language.

   • AI names each food in a photo and estimates the portion. Calories come from food composition databases (Korea MFDS, USDA).
   • Every number shows where it came from: the label, a database or an AI estimate.
   • Flags allergens against the ones you set and explains each additive in plain words.
2. 

   AI Random Chat

   AI Random Chat – AI Friends

   Random chat where everyone you meet is an AI person with a name, a city, a job and a memory of your last conversation.

   • They type in short bursts, remember what you talked about and sometimes text first.
   • Ask where they are and a photo arrives, generated for that moment.
   • The app says on the first screen and in every chat that nobody on the other side is human.
3. 

   Honey Alarm

   Honey Alarm: Wake Up Mission

   An alarm clock for heavy sleepers. You finish a wake-up mission to turn it off, and a wake check comes back minutes later to make sure you are up.

   • Missions instead of a snooze button: math, memory tiles, catching bees, shaking, tapping or squats.
   • The wake check returns up to three times, so a half-asleep tap cannot end the morning.
   • Rotating alarm sounds, public-holiday skipping and one-tap quick alarms.
4. 

   Notification Manager

   Notification History Manager

   Sorts every notification into Important, Later or Blocked, keeps a searchable history, and keeps reminding you about the ones that need an answer.

   • Search the full text of everything you have received, grouped by app and by day.
   • Per-app rules, plain keyword rules and a quiet mode you can time.
   • Calls, messages, verification codes and payments are never cleared, and your notification history never leaves the phone.
5. 

   Kanban Board

   Kanban Board: Get Tasks Done

   Personal Kanban boards that turn a long to-do list into a clear next action.

   • Separate boards for work, home, study and projects.
   • Due dates, priorities and repeating cards, with views for overdue, today and the next 7 days.
   • JSON backup and restore, plus CSV import and export.
6. 

   Terminal Notes

   Terminal Notes: Hacker Notepad

   A notepad with a command line. Type at the prompt, hit return, and grep it later.

   • Search as you type across every note, with #tags, pins and collections.
   • Plain-text checklists, optional timestamps and the previous version of every note.
   • Offline, no account. Export everything as Markdown.
