## Description

Altimeter+ determines your current altitude using GPS, ASTER, or the built-in barometer (iPhone 6 and later). It also computes GPS/ASTER elevation averages and presents an integrated map with peak indicators, a compass, and a distance grid for easy navigation.

Key features include Apple Watch support, imperial or metric units, and an option to operate without active GPS. Peak data are sourced from peakhunter.com, providing reliable altitude context on the go.

## Rankings

## Review summary

Altimeter+ is praised for accurate altitude readings and reliable performance across many locations, with useful options like calibration via known altitude and multiple data sources. Real-world use cases such as camping, hiking, and teaching are common positives, and features like Google Earth integration add value. The price is attractive for a long-standing tool. A recurring drawback is barometer calibration not working well on Apple Watch, which hampers the main feature for some users. Overall, reliability and versatility are the strongest assets, with calibration on watch a key area for improvement.

### Pros

- Accurate, reliable altitude readings across diverse locations.
- Ability to calibrate using a known altitude for improved precision.
- Multiple data sources to choose from for altitude data.
- Useful for real-world activities (camping, hiking, skiing) and education.
- Google Earth integration for quick zoom-in from the altimeter; good value at 99 cents.

### Cons

- Barometer calibration (notably on Apple Watch) not working reliably across devices, limiting the core feature.
