No subscription. • Already bought DevGantry? You own the Full Version. It is recognized automatically — nothing to do, nothing to pay. • Locked tools show a lock badge in the sidebar and Quick Open; Settings gains a Full Version section with Unlock and Restore Purchases. FIXES • Device Info's Monitor no longer slides back and forth forever when opened on macOS. • The iOS battery level is shown as approximate (≈NN%), matching what iOS actually reports to apps. • AI Prompts draws each prompt as a rounded card. ### 1.1.0 — 2026-08-29 Version 1.1.0 adds three new tools, a live device monitor, and a faster app all round. NEW TOOLS • Network Tools — DNS lookup, HTTP(S) inspector, TCP port scan, WHOIS/RDAP, and offline local-network info, all in one place. • AI Prompts — save and search your AI prompts, synced across your devices with iCloud. • AI Prompt Creator — build a prompt section by section (task context, background documents, rules, examples) and export it as XML, Markdown, or plain text. DEVICE MONITOR • Device Info gains a Monitor mode with live CPU, memory, and network graphs — and you can save a snapshot to history. IMPROVEMENTS • Image tools can now pick from the Photo Library on iPhone and iPad, alongside Files. • Brackets and quotes auto-close as you type in the code editors, with skip-over and pair-delete. • JWT segments and regex matches are now color-coded, so structure is easier to read at a glance. • HTML Preview opens .html files from the file picker or by drag-and-drop. • Color Converter carries alpha through, so transparency survives the round trip. • History loads the newest 200 entries with a Show More button, so a long history opens instantly. • Faster launch, cached tool search, and debounced text tools across the app. FIXES • Clearing History no longer freezes the app — it runs in the background and the sheet stays responsive. • Device Info's Monitor no longer stalls when you open the tab or come back to it. • Label and value rows show their full content on iPhone instead of truncating. ### 1.0.0 — 2026-08-12 No release notes. ## More apps by A&A GLOBAL INTERNATIONAL LLC - [Crown Racer](https://appshunter.io/ios/app/crown-racer/id6743194481) - [YUPE - Dine Anywhere](https://appshunter.io/ios/app/yupe-dine-anywhere/id6743195643) All apps by A&A GLOBAL INTERNATIONAL LLC: https://appshunter.io/developer/1798565341 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
