HazechoBetaA roast log for hand-pan coffee roasting

FreeNo sign-upRuns in your browser5 languages

Hazecho is currently in beta. Features and screens may change without notice, so please back up your records from time to time.

Hazecho records the moment each crack happens when you roast coffee beans in a hand pan or skillet, with a single tap. The big buttons are easy to hit while you keep the pan moving, and they log every stage from preheat to drop. Save the times together with a photo and a note on the finished beans, and you will know how to roast your next batch.

  • Roast recordsKeep the bean name, green weight, roast level, a photo and a short note. Forgot to tap? Fix any time afterwards, down to the second.
  • Search your roastsSearch by bean name or note, filter by roast level, and compare with past roasts.
  • Images for social mediaCreate a post image from three templates (Card, Film and Stamp), with a caption drafted for you.
  • BackupExport your records to a JSON file and import them again, for example when you change phones.

  1. Put the pan on the heat and tap “Start preheat”.
  2. When the pan is hot, add the beans and tap “Add beans”.
  3. Tap “1st crack!” at the first pops and “2nd crack!” when the crackling starts.
  4. Tap “Drop” when the color looks right, then take a photo of the beans and save.

Schoolyard SoccerBetaA 5-a-side soccer brawl for your phone (熱闘！校庭サッカー)

FreeNo sign-upRuns in your browserPhone and PC

Schoolyard Soccer is currently in beta. We are still tuning the controls and the strength of the rival schools.

A pixel-art soccer game where two teams of five battle it out in a schoolyard. Slide-tackle your way to the ball, then unleash a special shot when your gauge is full. Beat all five schools in the area to win the schoolyard league. A match takes as little as two minutes, so it fits into any short break.

Features

  • Touch controlsDrag on the left side of the screen to move, and use the Z, X and C buttons to shoot, pass and jump. On a PC, play with the keyboard.
  • Slide tackles and special shotsWithout the ball, Z is a slide tackle. Shoot in mid-air for a jumping shot, or fire a special shot when your gauge is full.
  • Five rival schoolsEach school differs in speed, passing and goalkeeping. Your win/loss record against each school is kept.
  • Name your teamGive your team any name you like (up to 8 characters).

How to play

  1. Enter a team name on the title screen and choose an opponent.
  2. Pick a school on the map, choose a match length (2, 3 or 5 minutes) and kick off.
  3. Win the ball and score. The team with more goals at the final whistle wins.
Your team name and match records are stored only in your browser and are never sent to our servers. The game is currently available in Japanese only.
