matt@cheklist.io
- habanero
- soylent
- longevity protein
- dragon fruit
- onions
- bird seed
the cook saves the soylent sliders
the cook looks at matt's ingredients cheklist while preparing the meal and sees that he doesn't like onions. he omits the onions from the sliders and saves matt from an onion disaster. ...and matt lives happily ever after.
you can use the chek-in app with no developer customization. it's nice to have the option if you want it.
