測量 座標計算 vs Formation
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
測量 座標計算
This app simplifies construction surveying by calculating angles and distances using the reverse traverse method. Input known coordinates and it computes unknown points, eliminating the need for manual scientific calculator work on-site. Elevation calculations are also supported.
- Reverse traverse method calculations
- Input XY coordinates
- Calculate contained angle
- Calculate distance
- Elevation calculation

This application employs the reverse traverse method used in construction. Simply using this application onsite will relieve you from the effort of pointless calculations with a scientific calculator by calculating numbers for you. [Reverse Traverse Method] By inputting the XY coordinates of the instrument and backsight points, then inputting unspecified XY coordinates, the contained angle and distance will be calculated. Elevation can also be calculated.
Formation
Design and share stage formations for dancers and performers. This app allows you to create projects, add members, and visualize positions with different background options. Export your configurations as images or PDFs to share with others.
- Create stage position configurations
- Add/remove dancers and slides
- Preview each slide
- Switch background styles
- Clone projects
- Share as image or PDF

Verdict
The clearest difference is review sentiment: Formation at 60% against 測量 座標計算's 18%. Formation also leads on update cadence (weekly vs monthly) and iOS requirement (10.0 vs 14.1). 測量 座標計算's advantage is price ($1.99 vs $2.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
