The calculator now opens empty and never fills in values for you: frequency, poles, connection, parallel circuits and wire quantity must be entered or picked before you can calculate. After a nameplate scan, anything the photo did not show stays empty, a checklist shows what is still missing, and "Use these values" waits until the plate's key values are filled. New tips help you take a sharper photo. ### 2.2.0 — 2026-09-26 Store listing in Portuguese, French and German. A clearer Pro button. ### 2.1.0 — 2026-09-25 Improvements and bug fixes. ### 2.0.0 — 2026-09-25 No release notes. ## Apps similar to AC Motors | App | Rating | Price | Category | | --- | --- | --- | --- | | [AmpCore](https://appshunter.io/ios/app/ampcore/id6791554213) | — | Free | Utilities | | [DC Electric Generator](https://appshunter.io/ios/app/dc-electric-generator/id6478043321) | 5.0 (5) | Free | Utilities | | [Timer®](https://appshunter.io/ios/app/timer/id6450411439) | 4.7 (103) | Free | Utilities | | [Caliper&Ruler](https://appshunter.io/ios/app/caliper-and-ruler/id6749051381) | 5.0 (1) | Free | Utilities | | [My IP - Find & Show IP Address](https://appshunter.io/ios/app/my-ip-find-and-show-ip-address/id6737197297) | 4.7 (18) | Free | Utilities | | [Simubus](https://appshunter.io/ios/app/simubus/id6757686667) | — | Free | Utilities | ## More apps by Luis Torres - [dotMD: Markdown Notes & Editor](https://appshunter.io/ios/app/dotmd-markdown-notes-and-editor/id6797048581) - [Indaga: UX & CX Insights](https://appshunter.io/ios/app/indaga-ux-and-cx-insights/id6819921600) All apps by Luis Torres: https://appshunter.io/developer/6797048583 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
