Alturos
Read full descriptionHide full description
This small and simple app will use the phones sensors to measure an current (absolute) altitude. You can also set a baseline and measure from there (relative measurement). The app is perfect for measuring height of for example an elevator. Notes: * The absolute height can be affected by weather. * The relative sensor might drift over time.

Verdict
The clearest difference is in-app purchases: Alturos at none against Omni Meter's 3. Omni Meter's advantage is update cadence (every 3 weeks vs every 7 months) and device support (3 vs 1). On price, ads and iOS requirement there is nothing between them.
