Built for students, teachers, technicians, and engineers, it combines a polished mobile experience with a powerful technical workflow for fast, accurate analysis of unbalanced three-phase systems in the field, lab, or classroom. The app performs both phase-to-sequence and sequence-to-phase transformations, with support for inputs in polar and rectangular form. It quickly resolves three unbalanced phase quantities into their positive-, negative-, and zero-sequence components, making it a practical tool for protection studies, fault analysis, system modeling, relay validation, and coursework. More than a single-purpose calculator, Phase Calc is packed with specialized calculators, technical reference libraries, and built-in formulas to support everyday power systems work. Whether you are checking values, reviewing theory, or working through engineering problems more efficiently, the app puts essential tools in one place. Results can be exported instantly, including vector data for plotting and graphical analysis, as well as technical report exports for documentation, review, and sharing. With powerful capabilities in a streamlined interface, Phase Calc delivers a complete mobile toolkit for three-phase analysis on iPhone and iPad. ## Phase Calc Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/e0/f0/c4/e0f0c46d-25db-b6c1-68f6-c1e1823ae8ab/IMG_8458.png/1320x2868.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/40/40/c5/4040c5d4-31c5-e056-23ca-7a85af2d0d63/IMG_8465.png/1320x2868.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/36/2c/1f/362c1f1e-3d0e-f217-7ff9-5606af38376f/IMG_8470.png/1320x2868.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/f6/b5/ec/f6b5ec01-cec6-34c6-afcf-e0fcedae80e9/IMG_8463.png/1320x2868.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/b0/f8/df/b0f8df56-af7a-f0d2-e14b-d8e07a4200ac/IMG_8471.png/1320x2868.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/64/ff/b0/64ffb018-8cc8-cb43-68a5-169059f55bce/IMG_8459.png/1320x2868.png) - [Screenshot 7](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/ec/09/d8/ec09d88f-3fb0-5cdc-4b3e-d2da28907c60/IMG_8464.png/1320x2868.png) - [Screenshot 8](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/5e/5f/04/5e5f04f3-69bb-0ee6-b6a5-2550648ef73e/IMG_8472.png/1320x2868.png) - [Screenshot 9](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/69/cc/f1/69ccf15c-060f-406f-8ff1-5b2a1209cb9e/IMG_8476.png/1320x2868.png) - [Screenshot 10](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/f2/ec/97/f2ec974e-3a77-1ca0-9815-a9099de6d8c6/IMG_8481.png/1320x2868.png) ## Phase Calc Rating Breakdown in United States - 5 stars: 4 (100%) - 4 stars: 0 (0%) - 3 stars: 0 (0%) - 2 stars: 0 (0%) - 1 stars: 0 (0%) ## Phase Calc Discovered Keywords - phase calc ## Phase Calc Available In - [United States](https://apptail.io/app/phase-calc-ilHf/united-states) - [Australia](https://apptail.io/app/phase-calc-ilHf/australia) - [Brunei](https://apptail.io/app/phase-calc-ilHf/brunei) - [Canada](https://apptail.io/app/phase-calc-ilHf/canada) - [China](https://apptail.io/app/phase-calc-ilHf/china) - [Czechia](https://apptail.io/app/phase-calc-ilHf/czechia) - [Germany](https://apptail.io/app/phase-calc-ilHf/germany) - [Denmark](https://apptail.io/app/phase-calc-ilHf/denmark) - [Algeria](https://apptail.io/app/phase-calc-ilHf/algeria) - [France](https://apptail.io/app/phase-calc-ilHf/france) - [Greece](https://apptail.io/app/phase-calc-ilHf/greece) - [Croatia](https://apptail.io/app/phase-calc-ilHf/croatia) - [Hungary](https://apptail.io/app/phase-calc-ilHf/hungary) - [Iceland](https://apptail.io/app/phase-calc-ilHf/iceland) - [Jamaica](https://apptail.io/app/phase-calc-ilHf/jamaica) - [Thailand](https://apptail.io/app/phase-calc-ilHf/thailand) - [Vietnam](https://apptail.io/app/phase-calc-ilHf/vietnam) - [United Arab Emirates](https://apptail.io/app/phase-calc-ilHf/united-arab-emirates) - [South Africa](https://apptail.io/app/phase-calc-ilHf/south-africa) - [Bulgaria](https://apptail.io/app/phase-calc-ilHf/bulgaria) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
