3D Interpolation vs Thermal Transmittance Calc
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
3D Interpolation
Calculate key directional drilling parameters like TVD, coordinates, and displacement. This tool aids drilling engineers and students in oil well directional drilling by interpolating survey data.
- Calculate TVD, N/S, E/W coordinates
- Determine Horizontal Displacement
- Calculate Dog-Leg Severity
- Measure Build-Up Rate
- Calculate Turn Rate
- Interpolate parameters between survey stations

The 3D Interpolation provides an useful tool to calculate projections TVD (True Vertical Depth), N/S and E/W coordinates, Horizontal Displacement, Dog-Leg Severity, Build-Up Rate (Angle Rate, Intensity) and Turn Rate and also the Interpolation of these parameters between two well planning sections or survey stations defined by Measured Depth, Inclination and Azimuth as entry parameters in the directional drilling of oil wells. Calculations Method: Minimum Curvature Length Units: Foot and Meter (Metre) Intensity Units: degree/100ft, degree/10m, degree/30m and degree/100m Our goal was to create a low-cost application with the help of experts to share with drilling engineers, technicians, drillers, students and teachers of drilling engineering. You can contribute with suggestions for improvements, correcting the translation to english, reporting bugs and sharing it with your friends.

Thermal Transmittance Calc
Calculate heat loss and humidity issues in building structures. Input air temperature, humidity, and material layers to visualize temperature and dew point changes. Supports both Celsius/Fahrenheit and cm/inches.
- Calculate heat loss
- Identify humidity problems
- Visualize temperature and dew point changes
- Supports Celsius and Fahrenheit
- Supports centimeters and inches
- Easy data entry and immediate results

This application allows you to help in checking the existing and planning future isolation. After entering data on the temperature and humidity of the air and selecting all layers of the enclosing structure (starting from inside the building and ending with the exterior trim of the facade or roof) in the Thermal Transmittance Calc, you will receive information on all likely heat losses, as well as possible problems with humidity. A schedule will be built, according to which you can track how the temperature and humidity will change and where the dew point in the layers of the structure will be. - Easy to use, enter all the data and immediately get the results. - Ability to enter the temperature in both Celsius and Fahrenheit. - Ability to enter the size of the layer in centimeters and inches.

Verdict
The clearest difference is review sentiment: Thermal Transmittance Calc at 75% against 3D Interpolation's 0%. Thermal Transmittance Calc also leads on price (Free vs $9.99) and update cadence (every 11 months vs every 37 months). 3D Interpolation's advantage is in-app purchases (none vs 2) and ads (none vs shown). On device support there is nothing between them.
