No publisher influence. > **Key Insight:** Mud fluid is a reference app by Dmitry Pavlov. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Reference | | **Developer** | Dmitry Pavlov | | **Pricing** | Free | | **Platforms** | iOS | | **Confidence** | Low (0.05/1.0) | | **Data Age** | 44d | ## Metadata & Market Performance - **Publisher:** Dmitry Pavlov - **Category:** Reference - **Target Audience:** Mud engineers and drilling professionals requiring field-ready calculation tools for wellbore flushing and fluid management. - **Platforms:** iOS - **Version Reviewed:** 2.0.0 - **Report Date:** 2026-09-29 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.05/1.0) - **App Store ID (iOS):** 1582369827 - **Bundle ID:** com.DmitryPavlov.mud-engineer - **Data Window:** Analysis based on signals collected up to 2026-09-29 ## Executive Snapshot **What it is:** Mud fluid is a reference utility for mud engineers that calculates wellbore flushing times and fluid density on iOS. **Why users hire it:** It removes the cognitive load of manual interval-based calculations during drilling operations, serving professionals who need immediate, field-ready data. ## App DNA (Features & Intent) - **[Standard] Wellbore Flushing Calculator:** Calculates time and volume for wellbore flushing across surface casing, production casing, and liner intervals. * *User Intent:* Users seek enhanced value through premium features. - **[Standard] Solution Weight and Dilution Calculator:** Computes fluid density and dilution requirements for mud engineering tasks. - **[Basic] Metric Unit Support:** Provides calculations exclusively in metric units for drilling operations. * *User Intent:* Users seek enhanced value through premium features. ## Market Position {#market-position} Mud fluid serves a specialized professional niche in the Reference category with no active monetization. The 150-day update gap signals a maintenance-mode posture that leaves the tool vulnerable to competitors offering broader unit-system support. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** Mud fluid is currently offered as a free utility with no visible monetization or subscription gates. ## SWOT Analysis {#swot} **Core Strengths:** - Interval-based calculation logic for casing and liner segments **Growth Levers:** - Adding imperial unit support unlocks North American drilling markets ## What's New - **Latest (v2.0.0, 5 months ago):** Launched a complete app redesign. ## App Momentum (Maintenance) {#momentum} - Shipped complete app redesign. - Quiet 5 months, no updates. > **Cadence:** 1 total versions · 1 majors in last 6 months · 150 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Mud fluid is a reference app that is completely free. > **Bottom Line:** Mud fluid provides a focused utility for drilling professionals, but the lack of imperial unit support restricts its reach. Prioritizing unit-system expansion would address the primary friction point for international engineers, securing the tool's relevance in global drilling operations. **Best for:** Mud engineers and drilling professionals requiring field-ready calculation tools for wellbore flushing and fluid management. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship imperial unit support because it is the primary barrier to international adoption → increase total addressable market ### Outlook: Stable The drilling utility market remains stable, with demand driven by specialized professional workflows. Mud fluid is currently advantaged by its focused feature set, but the lack of imperial unit support creates a ceiling for growth that will require a development pivot to overcome. - ⚪ The latest release (v2.0.0) delivered a complete redesign, signaling that the tool remains functional despite a 150-day maintenance-mode gap. - 🔴 The absence of imperial unit support limits the tool's utility in non-metric drilling regions, which restricts the potential for user base expansion. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Mud fluid** (this app) | N/A/5 | N/A | Dmitry Pavlov | | [올어바웃성경](https://marlvel.ai/apps/com-allabout-bibleapp) | 5.0/5 | N/A | Gilju Lee | | [Hallow: Prayer & Meditation](https://marlvel.ai/apps/hallow-prayer-meditation) | 4.7/5 | n/a | Hallow, Inc. | | [고려대 한국어 속담 사전](https://marlvel.ai/apps/app--428) | N/A/5 | N/A | DaolSoft, Co., Ltd. | | [우리말 의학사전](https://marlvel.ai/apps/app--427) | N/A/5 | N/A | DaolSoft, Co., Ltd. | | [공인중개사 용어사전](https://marlvel.ai/apps/app--429) | N/A/5 | N/A | DaolSoft, Co., Ltd. | ## Company Profile - **Developer:** Dmitry Pavlov ## Data Sources & Links - **App Store ID:** 1582369827 - **Sources:** App store metadata. ## Related Intel Reports - [*올어바웃성경*](https://marlvel.ai/apps/com-allabout-bibleapp) (Gilju Lee) · 5.0/5 Rating - [*Hallow: Prayer & Meditation*](https://marlvel.ai/apps/hallow-prayer-meditation) (Hallow, Inc.) · 4.7/5 Rating - [*고려대 한국어 속담 사전*](https://marlvel.ai/apps/app--428) (DaolSoft, Co., Ltd.) · N/A Rating - [*우리말 의학사전*](https://marlvel.ai/apps/app--427) (DaolSoft, Co., Ltd.) · N/A Rating - [*공인중개사 용어사전*](https://marlvel.ai/apps/app--429) (DaolSoft, Co., Ltd.) · N/A Rating - [*브리태니커 콘사이스 백과사전*](https://marlvel.ai/apps/app--425) (DaolSoft, Co., Ltd.) · N/A Rating - [*100 Radio Hrvatska (HR) : Vijesti, glazba, Nogomet*](https://marlvel.ai/apps/100-radio-hrvatska-hr-vijesti-glazba-nogomet) (Thomas Gesland) · 1.0/5 Rating - [*100 US Citizenship Test Questions 2017*](https://marlvel.ai/apps/100-us-citizenship-test-questions-2017) (Andrey Fetisov) · 4.7/5 Rating - [*١٠١ پرسیار لە زانستی قورئان*](https://marlvel.ai/apps/app--952) (Abdulwahab F.
