True Position vs Thread Calculator
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
True Position
This app calculates the true position of holes based on engineering drawing dimensions and tolerances. It helps determine if hole positions meet required specifications, with or without Maximum Material Condition. It's a tool for manufacturing quality control.
- Calculate true position of holes
- Enter engineering drawing dimensions
- Account for specified tolerances
- Supports Maximum Material Condition
- Checks if hole positions are within tolerance

A calculator for finding the true position of holes. Enter the dimensions and tolerances from the engineering drawing. In manufacturing, this will help you to calculate whether the position of holes meet the required tolerance. Calculates results both with and without Maximum Material Condition. True position is the deviation from the theoretical location of the hole or feature as shown on the drawing. A True Position of 0.000 would mean the hole is exactly where it is supposed to be. A True Position of 0.010 means the hole is 0.010 off from where it is supposed to be. If that 0.010 is more than the tolerance given on the drawing then the true position of the hole is out of tolerance.
Thread Calculator
This app provides a quick and easy way to calculate thread dimensions for various units, including tap hole sizes and bolt specifications. It helps metalworkers find precise measurements for internal and external threads without consulting tables.
- Thread cutting calculator for multiple units
- Cold forming calculator
- Thread repair calculator
- Tap hole and bolt diameter calculation
- Saves time compared to tables

Verdict
The clearest difference is rating: Thread Calculator at 4.3 against True Position's 3.0. Thread Calculator also leads on update cadence (every 18 months vs every 46 months) and ratings volume (13 vs 4). True Position's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, review sentiment, in-app purchases and device support there is nothing between them.
