About

Hygrometer Barometer

This app measures relative humidity and calculates the discomfort index using your current location. It displays humidity in a badge and offers barometric readings for compatible devices. Use it to gauge outdoor conditions for appropriate clothing choices.

Highlights
  • Measures relative humidity via GPS
  • Calculates discomfort index (DI)
  • Displays humidity in badge
  • Barometric pressure readings (iPhone 6+)
  • Outdoor humidity reference
Features
Read full description

A simple popular free humidity meter application that measures the relative humidity of the current location measured by GPS and displays it as a percentage. Calculation function with formula of discomfort index (DI) from humidity and degree of Celsius. Humidity is displayed in badge. Barometric function by pressure sensor (iPhone 6 / Plus or later). Because it is outdoor humidity instead of indoor humidity, it is a reference for outfit clothing. Some areas are excluded.

About

HgBarometer

This app assists users of mercury barometers by simplifying pressure calculations. It helps determine barometric pressure by accounting for meniscus height, instrument temperature, and local gravity. It also offers unit conversions and can be used to calibrate barometers.

Highlights
  • Simplifies mercury barometer pressure calculations
  • Accounts for meniscus height, temperature, and gravity
  • Supports multiple pressure units
  • Facilitates barometer calibration
  • Allows sharing of observations and results

Read full description

This app is an invaluable companion for users of mercury barometers. It is also of a highly didactical value for the understanding of barometric pressure related phenomena like different measurement units for this quantity. When using an old-style mercury barometer one must determine the heights at the top and at the glass contact of the meniscus. Moreover, the instrument temperature as well as the gravitational acceleration at the site is needed to estimate the actual barometric pressure. In the past cumbersome tables or laborious calculations were needed to correct the various influence quantities. This app saves you from this trouble. On selected devices you can compare the build-in altimeter with the calculated pressure value of the mercury barometer. Features: - Natural user interface. - Choice between many different pressure units. - Observations and results can be shared in various ways. - May be used to calibrate your mercury barometer (or your iOS device, whichever you deem more accurate)

Verdict

The call

The clearest difference is in-app purchases: HgBarometer at none against Hygrometer Barometer's 1. HgBarometer also leads on ads (none vs shown). Hygrometer Barometer's advantage is ratings volume (152 vs 1) and rating (4.3 vs 4.0). On price, update cadence, device support and iOS requirement there is nothing between them.
