Mud Engineer
Mud Engineer is a drilling fluid calculation tool for field engineers, available on iOS and Android.
The App DNA
What makes this app unique?
It removes the cognitive cost of manual drilling equations by providing step-by-step verification and professional PDF documentation for wellsite reports.
For Fluids supervisors, wellsite mud engineers, and laboratory technicians.
What does it look like?
Key features
Calculates mud weight, hydrostatic pressure, ECD, and annular velocity for field operations.
Generates professional PDF reports with custom branding and watermarks.
Automatically saves and archives past calculations for quick retrieval.
How much does it cost?
The developer employs a platform-specific split, gating professional PDF reporting behind a one-time purchase on iOS while maintaining a free ad-supported model on Android.
Velocity
Maintenance developmentnew contentUX improvementsperformanceShow more...
With only one release in the last 113 days and a significant gap between the current and previous versions, the app operates on a maintenance cadence. Development is infrequent, characterized by long periods of inactivity followed by occasional feature-rich updates. While the latest release added significant utility, the overall trend indicates a lack of consistent, ongoing development. The app currently averages less than one release every three months.

Competitive landscape for Mud Engineer
How's the Business market?
Mud Engineer maintains a 4.2 rating on Android but struggles with a 1.0 rating on iOS, signaling significant friction in the paid-tier experience. The lack of metric support limits its reach in international markets where rivals like ECD Calculator dominate.

By Halliburton
Both apps target field engineers performing drilling calculations, but Halliburton eRedBook captures the international market by providing native metric unit support that Mud Engineer lacks.
- Halliburton eRedBook includes native metric and imperial unit toggles for all volume calculations.
- Halliburton eRedBook provides integrated API specifications for casing, tubing, and drill pipe dimensions.
- Mud Engineer offers professional PDF reporting and automated calculation history for field documentation.

Key takeaways for Mud Engineer
Where is it heading?
The drilling fluid calculation market is consolidating around free, unit-flexible tools that integrate industry-standard data. Mud Engineer's reliance on a paid iOS model and its failure to support metric units leaves it exposed to faster-moving rivals, which will likely accelerate user churn into the next quarter.
- The lack of metric support forces European users to perform manual conversions → increased churn to unit-flexible rivals like ECD Calculator.
- Maintenance-mode release cadence leaves Mud Engineer exposed to rivals with 2-week update cycles → erosion of technical relevance in the field.
The SWOT
- Professional PDF reporting enables structured documentation workflows
- Automated calculation history reduces data re-entry friction
- Step-by-step equations provide technical transparency for field verification
- Localized unit support could capture international user base
- Expanding calculation suite to include IADC-compliant kill sheets
- Integrating API-compliant data to improve industry-standard trust
Next best moves
Ship native metric unit support because user complaints cite this as the top friction point → reduce churn to international rivals

Native metric unit support (available in Halliburton eRedBook but missing here) +2
Since the last report: The competitive outlook has declined as the app's paid iOS model and lack of metric support drive users toward free, more flexible alternatives. The analysis now explicitly frames the $2.99 price point as a barrier to retention rather than a signal of quality.
Bottom line
Mud Engineer's professional reporting provides a clear utility, but the lack of metric support and the paid iOS barrier are driving users to free, more flexible rivals. Pivoting to a freemium model and localizing units would unlock the international field-engineer segment.
