FieldKit is a focused, no-nonsense field recorder built for sound designers, foley artists, ambient musicians, and anyone who needs to capture the world in high fidelity. RECORD IN STUDIO QUALITY Capture 24-bit, 48kHz WAV audio with real-time waveform monitoring. Adjust input gain, apply a low-cut filter to tame wind and handling noise, and monitor your input live — all before you hit record. SEE THE SOUND Watch a real-time spectrogram as you record, so you can spot frequency content the waveform alone won't show you. Perfect for catching hums, resonances, and details you'd otherwise only notice on playback. STAY ORGANIZED Every recording can be automatically geotagged, so you always know where a sound was captured. Tag recordings by type, add timestamped markers while recording or editing, and search your entire library instantly. EDIT WITHOUT LEAVING THE APP Trim recordings non-destructively, drop markers to bookmark key moments, normalize levels, adjust gain with one-tap undo, and automatically detect and strip silence — all without needing a separate editor. EXPORT YOUR WAY Export to WAV, AIFF, M4A, or FLAC with embedded metadata (title, location, tags, markers). Split a recording into separate files at your markers, or batch export your whole library at once. BUILT FOR EXTERNAL MICS FieldKit supports external microphones and includes a screen-flip mode for rigs where your phone ends up mounted upside-down. PRIVACY FIRST All processing happens on your device. FieldKit doesn't collect any data, doesn't use analytics or tracking, and doesn't require an account. Your recordings never leave your phone unless you export them yourself. FieldKit Pro is a one-time purchase — not a subscription — and unlocks: • Unlimited recordings • Real-time spectrogram view • Unlimited tags • Batch export • Export as slices • Normalize & gain tools • Silence detection & auto-crop Everything else is free, forever.

About

OBD2+

Features
Read full description

OBD2 Plus is a vehicle diagnostic app for iPhone that connects to a compatible Wi-Fi OBD2 / ELM327 adapter. IMPORTANT: A compatible Wi-Fi OBD2 adapter is required to obtain vehicle data. The adapter is not included with the app and must be purchased separately. Connect the OBD2 adapter to your vehicle's OBD2 port, then connect your iPhone to the adapter's Wi-Fi network. Main Features • Real-time vehicle speed • Engine RPM • Coolant temperature • Engine load • Intake air temperature • Intake manifold pressure • MAF air flow • Throttle position • Fuel level • Vehicle voltage • Hybrid-related data on supported vehicles • VIN reading • Diagnostic Trouble Code (DTC) reading • DTC clearing • Real-time CAN communication monitoring • CAN ID filtering • RAW CAN data and bit-level display • Manual OBD2 command transmission • Advanced CAN frame transmission • Communication log saving and sharing • Driving location display using iPhone location services Compatible Hardware OBD2 Plus is designed for Wi-Fi-enabled OBD2 adapters, including compatible ELM327-based devices. Requirements: • iPhone • Wi-Fi-enabled OBD2 / ELM327-compatible adapter • Vehicle equipped with a compatible OBD2 port Bluetooth-only OBD2 adapters are not supported. Compatibility and available data may vary depending on the vehicle model, model year, ECU, vehicle specifications, and OBD2 adapter. Location Services If location access is permitted, OBD2 Plus can use the iPhone's location information to display the current or recorded driving position on a map. Location access is optional. OBD2 diagnostic features that do not require location information can still be used without location permission. Privacy Vehicle data, VIN, DTCs, CAN data, OBD2 communication data, and location information are generally processed locally on the user's iPhone. OBD2 Plus does not transmit this vehicle information or location information to external servers managed by the developer. The app does not require user registration or login. Safety Use OBD2 Plus only when the vehicle is safely stopped. Do not operate the app or your iPhone while driving. Clearing DTCs does not repair the underlying cause of a vehicle fault. If the cause remains unresolved, the diagnostic trouble code or warning light may return. CAN transmission features are intended for users who understand vehicle communication. Sending incorrect CAN frames may cause unexpected vehicle ECU behavior. After use, disconnect the OBD2 adapter from the vehicle if appropriate to avoid unnecessary auxiliary battery drain.
