# NxtTools > Last updated: 2026-06-25 > NxtTools is a free, all-in-one productivity utility app for iOS and Android. It bundles a document scanner, QR Bundle creator, PDF tools (compress, merge, grayscale, monochrome, enhance, extract pages, export as images), image tools (compress, rotate, flip, crop, resize, enhance), a document viewer (Word, Excel, PowerPoint, CSV, RTF, ODF), digital signatures with calligraphy fonts, and audio/video playback into a single app. Every currently shipped tool is free with no account required — banner ads on local tools, one reward ad on backend services. Subscriptions (ad removal) and AI tools are planned, not yet live. Web app coming soon — today the tools live in the iOS and Android apps. Built by Const Agility, LLC (Texas, USA). ## Mobile apps - [iOS App Store — NxtTools: QR, PDF, Doc Scanner](https://apps.apple.com/us/app/nxttools-qr-pdf-doc-scanner/id6758467117): Free download. iPhone and iPad.
