The app allows users to select Tubulars or BOPS to view specs. Users will also have access to our newly added API Casing General Information table. The initial page will allow the user to select between three sections of the app: Tubulars, BOPs, or Casing. Upon selecting "Tubulars" or "BOPs, the user will be presented with a built in table that contains essential information. Therefore, it does not require an internet connection to function! This will allow for constant, unhindered access to tubular and BOP information such as: tool joint OD, tool joint ID, max make up torque, premium tensile, BOP height, BOP weight, BOP pressure rating, BOP bonnet type, BOP operating data, and BOP shear testing videos. Upon selecting the "API Casing - General Information" button, the user will have access to a built in table containing standard API casing information. You can now view essential specs in areas where there is little or no cell phone reception. When selecting "Tubulars" or "BOPs", simply tap the item to view the spec sheet. This retrieves the spec sheet from our website, which can be shared using the button on the top right. (Please note: this function does require an internet connection). From there, the spec sheet can also be saved to your phone, or any handled via another app. We hope you enjoy this app as much as we have. Please feel free to provide feedback via the contact us button in the app.
Mud fluid
This app assists mud engineers with rapid calculations for wellbore flushing, including time and volume. It supports drilling intervals like surface casing and production casing, and can also compute solution weight and dilution. Metric units are currently available, with imperial units planned for a future update.

Mud fluid - an app for mud engineers that allows you to quickly calculate the time and volume of wellbore flushing. For convenience, well flushing is divided into drilling intervals: surface casing, production casing and liner. It is also possible to calculate the weight of the solution and the dilution. At the moment only metric units are available, in the future there will be an update to the ability to select imperial units

Verdict
The clearest difference is in-app purchases: Quail Tools at none against Mud fluid's 3. Quail Tools also leads on review sentiment (100% vs 77%) and iOS requirement (12.0 vs 16.1). Mud fluid's advantage is update cadence (every 2 weeks vs every 5 weeks). On price, ads and device support there is nothing between them.
