Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Energy Efficiency Suite
Read full descriptionHide full description
This is a suite of twelve apps published already are put together to facilitate as a tool for performing energy efficiency studies especially in energy intensive chemical and process industries as well as HVAC applications. Hence, this can serve as an onsite analysis tool for energy engineers, auditors and technical personnel for assessing the energy saving potential. Further it can save more than 50% in total cost of individual apps. Apps can be grouped under three different categories such as supporting apps, device apps and energy cycle apps as given below. Supporting Apps: 1. Thermo-Physical Properties (16 common industrial fluids) 2. Fluid ΔP (Fluid pressure drops in pipes and conduits) 3. Orifice flow (Measurement of flow rates in pipes) 4. Engineering unit conversion (SI to USCS unit conversion) Device Apps: 1. Boiler Fuel Efficiency (with CHP) 2. Centrifugal Pump Specification 3. Fan Specification Performance 4. Compressor Capacity Performance 5. Heat Exchanger Performance Energy Cycles 1. Rankine Cycle 2. HVAC Cooling Cycle 3. HVAC Heating Cycle Users can save all their application data pertaining to energy cycles as well as major devices (Boiler, pump, heat exchanger and fan-duct system) in a file with unique title for reviewing and monitoring individual performance time to time. Users can use either SI and USCS units for both inputs and output. Please note that CHP (Brayton) cycle is part of BoilerFE app. The screen shots shown are mainly for energy cycle (Rankine and HVAC cooling cycles) apps. Therefore, please refer App stores for all other individual app descriptions and screen shots that were already published. Additional details are also available at our web site www.flowjoule.com/download.html This application suite has all the current updates with bug fixes for devices with iOS 14.. and higher and this will be frequently updated with added features time to time.
E3 Drying
This utility app provides water mitigation professionals with proprietary algorithms and metrics to precisely control drying chambers. It introduces a patent-pending E3 metric to evaluate evaporation ability and set daily targets, allowing for optimized equipment selection and performance comparison.
- Proprietary algorithms for drying chamber control
- Patent-pending E3 metric for evaporation evaluation
- Daily E3 targets for various equipment and conditions
- Equipment ranking and comparison
- Control regardless of chamber size or outside conditions

This app is built for all levels of restorers in the water mitigation industry. For the first time ever these proprietary algorithms and metrics will give the restorer complete control of their drying chamber regardless of the size, class, equipment used or outside conditions instead of the restorer being controlled by their chamber. The keystone metric for this app is the patent pending E3 metric that can evaluate the exact evaporation ability of any condition in a drying chamber and the daily E3 targets that have been set for all different types of drying equipment for all possible water classes and outside conditions. This metric also allows for all different types of equipment to be specifically ranked or compared to prove which is the best for any job scenario.

Verdict
The clearest difference is price: E3 Drying at Free against Energy Efficiency Suite's $19.99. E3 Drying also leads on update cadence (every 3 weeks vs every 3 months) and iOS requirement (12.0 vs 14.3). On ads, in-app purchases and device support there is nothing between them.
