Hydrostatic Pressure Calculator is a physics/math calculator used to find hydrostatic pressure at a certain depth quickly and easily. Features: - Instant calculation - Results are copyable to other apps - Formulas are included as references - Supports up to 16 decimal places - Supports various units for each input - Lightweight app with a small size, optimized for everyday use Hydrostatic Pressure is the pressure exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity. Hydrostatic pressure increases in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above. Each particle of a liquid is subjected to a gravitational force directed towards the Earth. The deeper it is located, the more particles are above it, resulting in higher fluid pressure. The value of hydrostatic pressure does not depend on the size and shape of the tank, but only on the depth. Therefore, the same hydrostatic pressure will be present in a huge swimming pool and a thin pipe, provided they have the same height. Hydrostatic pressure formula: p = ρ * g * h where: p - hydrostatic pressure ρ - density of fluid g - gravitational acceleration (the average value for Earth is g = 9.80655 m/s²) h - depth Thank you for your support, and feel free to visit nitrio.com for more apps for your iOS devices.

Verdict
The clearest difference is rating: Hydrostatic Pressure Calc at 5.0 against EchoAccess's 3.5. Hydrostatic Pressure Calc also leads on iOS requirement (13 vs 17.0). EchoAccess's advantage is update cadence (every 4 months vs every 31 months) and chart position (#75 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

EchoAccess costs $2.99 and Hydrostatic Pressure Calc $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Hydrostatic Pressure Calc holds the better App Store score, 5.0 against 3.5. That said, the two scores are not equally well evidenced: EchoAccess has 8 ratings behind it against 1, so its average is the more settled of the two.
EchoAccess ships an update every 4 months, Hydrostatic Pressure Calc every 31 months. The most recent releases landed on November 11, 2026 and November 2, 2026 respectively.
