#SwiftUI Startups & Tools

Testing haptic feedback on an iPhone simulator is impossible because the simulator doesn't vibrate. Developers working with iOS haptics have long faced this gap between design and device reality. Haptics Explorer closes that gap by providing a hands-on testing environment for the full range of haptic patterns available on iOS devices. The app is built for iOS developers who need to feel haptic patterns on a real iPhone before shipping them into production. Rather than guessing at how a haptic will land, developers can preview each pattern, tweak its parameters, and copy ready-to-use code snippets directly into their projects. The product organizes haptic patterns into eight distinct categories. Developers can trigger impact patterns ranging from light to rigid, test notification feedback types like success, error, and warning, explore rhythm patterns such as heartbeats and tick-tock sequences, and experiment with gesture feedback for swipes, pinches, and long presses. Game-specific patterns for explosions and power-ups round out the library, alongside accessibility patterns and a custom pattern designer for building entirely new haptic experiences. What distinguishes Haptics Explorer is its focus on the actual developer workflow. Rather than abstract documentation or simulator tools that cannot replicate the real experience, this app bridges the gap by letting developers work directly on a physical device. The intensity and sharpness controls give fine-grained tuning, while the speed adjustment and looping features enable iterative testing. The code generation capability means developers can move from exploration to implementation without context switching or manual transcription. The app requires iOS 15.6 or later and runs on both iPhone and iPad. A 24 MB download size keeps installation friction minimal. Haptics Explorer is free to download from the App Store, supported by ads and basic anonymous analytics. The privacy model deserves a note: the app keeps data on-device by default, does not sell personal information, and limits itself to Google AdMob for ad serving. This positions it as straightforward tooling rather than a data-collection vehicle. For any iOS developer working with UIKit haptics, this app removes the guesswork from translating design intent to device behavior. It is a focused tool that solves a specific problem in a developer's workflow, which is exactly what developer tools should do.
