HelloBlue turns your iPhone or iPad into a Bluetooth Low Energy (BLE) debugging tool. Scan nearby devices, connect in a tap, explore every service and characteristic, send data, and watch the traffic live, all in one clean app. Built for firmware engineers, IoT developers, testers, and hardware makers who need to inspect and talk to BLE devices quickly. KEY FEATURES - Scan and connect Discover nearby BLE devices with live signal strength (RSSI). Search by name or UUID, sort by name or signal, rename devices, and reconnect to recent devices automatically. - Services and characteristics Browse every GATT service and characteristic. Read values as hex and text, write data, and subscribe to notifications. Give services and characteristics names that make sense to you. - Send data your way Send in Hex, String, or JSON. Save frequently used commands as quick texts and resend them with one tap. - Live operation logs Watch reads, writes, notifications, and errors stream in real time from any screen. Filter entries and turn auto-scroll on or off. - Session history Every session and automation run is saved. Review past logs, rename them, export them to share with your team, or delete what you no longer need. - Automation workflows Chain connect, write, delay, and loop steps into reusable flows. Set message intervals and repeat counts, and choose whether each step stops or continues on failure. - Location history HelloBlue records where a device was each time it connects, making it easier to find again. - iPhone and iPad Works on both, with layouts designed for each screen. Bluetooth must be turned on, and HelloBlue needs Bluetooth permission to scan and connect. Location history requires location permission. Some features depend on the services and characteristics your device provides.

About

Deploy Studio

Features
Read full description

Deploy Studio is a client for the App Store Connect API that can actually ship a release from a phone: pick a build, write release notes, answer export compliance, and submit the version — with its in-app purchases — for App Review. PREPARE AND SUBMIT A RELEASE • A release checklist that leads with what needs you and folds away what is already done • Plain language instead of Apple's error codes: "add at least one screenshot", not a status enum • Build, export compliance, What's New, screenshots, store listing, app information, age rating, price, App Review information, release option, and in-app purchases riding along • Submit for review when everything is green KNOW WHAT NEEDS YOU • One Today screen across every app: rejections, unanswered reviews, builds waiting on beta review, certificates about to expire • Notifications when a version is approved or rejected, checked in the background on your device • A Home Screen widget showing what the app last saw WHEN SOMETHING BREAKS • Crash reports from TestFlight testers with the full symbolicated log, copyable in one tap • Xcode Cloud runs broken into steps, with the errors from the step that failed • Start an Xcode Cloud build from anywhere • Signing that tells you which certificate expired before Xcode refuses to archive • API Status: whether App Store Connect is answering, and whether a failure is Apple's or your key's THE NUMBERS, HONESTLY • Downloads that exclude updates — counting updates as downloads overstates them several times over • Proceeds listed per currency rather than summed, because a total across storefronts is a number in no currency • Ratings and reviews, with replies YOUR KEY STAYS ON YOUR DEVICE Deploy Studio has no account and no server of its own. Your App Store Connect API key is stored in the device Keychain, never synced to iCloud, and used only to sign requests to api.appstoreconnect.apple.com. Tokens are minted on device and last twenty minutes. TRY IT WITHOUT A KEY Tap "Look Around First" on the first screen to explore every feature against sample data. Nothing is sent anywhere in that mode. Deploy Studio is free, with ads. A one-off Deploy Pro purchase removes them for good — no subscription, and every feature stays free either way. Deploy Studio is an independent app and is not affiliated with or endorsed by Apple Inc.
