My guess is that Apple didn't want their customers ruining their phone screens by putting heavy objects on it.

By accepting the app, Apple is implicitly allowing the use case of using the phone as a scale.

This may be a bigger issue than just concern that customers might ruin their screens (and blame Apple.)

Scales (for commercial use) are regulated, and devices marketed as scales but intended for only non-commercial use are explicitly labeled "not for us in trade"; Apple probably doesn't want to be seen as marketing or endorsing the iPhone as a scale, even implicitly.

That plus the fact that the sensor is probably not reliably calibrated between phones and may degrade with age. Apple doesn't want to deal with complaints about how their phone is doing a crummy job at weighing things.

Exactly this.

  "Oh, let's see how accurately it weighs 50lbs!"

Anyone remember the "waterproof" troll? Apple is protecting some of their users from their own stupidity.
