Same app, new name. Every calculator was rechecked against the 2021 IRC, IPC, and IFGC and manufacturer data, and many results changed: headers, joists, and deck beams now use the full IRC span tables; wire sizing respects NM cable limits; gas pipe uses the IFGC tables; drain slope, gutters, ventilation, ice barrier, thinset, grout, mud, and insulation were corrected. Also new: safety notes on every calculator, updated Terms of Use, October 2026 material prices, a thickened-edge option for slabs, and fixes throughout. ### 1.0 — 2026-04-06 No release notes. ## Apps similar to Trussly | App | Rating | Price | Category | | --- | --- | --- | --- | | [Parachute Backup Mobile](https://appshunter.io/ios/app/parachute-backup-mobile/id6749824842) | 4.6 (100) | $9.99 | Utilities | | [Viewu](https://appshunter.io/ios/app/viewu/id6502717790) | 5.0 (7) | Free | Utilities | | [PowerOne calculator](https://appshunter.io/ios/app/powerone-calculator/id1141498515) | 4.6 (803) | Free | Utilities | | [Roof Pitch Calculator Pro](https://appshunter.io/ios/app/roof-pitch-calculator-pro/id6748028349) | 4.6 (11) | Free | Utilities | | [Redodo](https://appshunter.io/ios/app/redodo/id6499311209) | 2.9 (55) | Free | Utilities | | [EG4 Monitor](https://appshunter.io/ios/app/eg4-monitor/id6448103545) | 3.3 (78) | Free | Utilities | ## More apps by Creayo LLC - [Bloopa](https://appshunter.io/ios/app/bloopa/id6747365442) - [Syllabound](https://appshunter.io/ios/app/syllabound/id6751174848) - [Moda: Driving Permit Hours Log](https://appshunter.io/ios/app/moda-driving-permit-hours-log/id6760154154) - [Impulse Buy Timer - Pausd](https://appshunter.io/ios/app/impulse-buy-timer-pausd/id6782400859) All apps by Creayo LLC: https://appshunter.io/developer/1814201467 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
