The simple free digital thermometer application that measures the ambient temperature of the current location measured by GPS and displays it in degrees Fahrenheit. The conversion calculator from Fahrenheit to Celsius with formula. Fahrenheit temperature is indicated in the badge (below zero is 1000, 1005 is -5 ℉). Barometric function by pressure sensor (iPhone 6 / Plus or later). Because it is outdoor temperature rather than indoor temperature, it is a reference for outfit clothes. Some areas are excluded. Displays sunrise time and sunset time.
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.
- 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

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 clearest difference is ads: HgBarometer at none against Fahrenheit Thermometer Plus's shown. HgBarometer also leads on update cadence (every 4 months vs every 10 months) and monetization model (free vs ad-supported). Fahrenheit Thermometer Plus's advantage is ratings volume (269 vs 1) and rating (4.3 vs 4.0). On price, in-app purchases, device support and iOS requirement there is nothing between them.
