Apple Health is great for this, but the process of adding data manually is tedious.
Thats why I built a shortcut to do it in two taps.
First, download the Shortcuts app from theApp Store(if you dont already have it installed).
Next, tap Add Action and use the search bar to find the Log Health Sample action.
Tap on it to add it to your Shortcuts workflow.
Now tap on the blue jot down field and select Weight from the list.

Tap on Sample Value and choose Ask Each Time from the field just above the keyboard.
Tap Rename and call it something like Record weight and then tap Choose Icon and pick something appropriate.
To save, hit Done in the top-right corner of the screen.
Using Your New Shortcut
The easiest way to use your new shortcut is to tap on it.
you could do this from within the Shortcuts app, but that still requires opening an app first.
There are faster ways to do this.
Scroll to the bottom, tap Edit then hit the plus + button at the top of the screen.
choose the Shortcuts to choose the first (most basic) widget and tap the Add Widget button.
The widget will be added, drag it into place and youre done.
you might alsoplace these widgets on a regular Home screenif youd rather.
I did this because I wanted an easy way to track progress when trying to lose weight.
