RequestLab vs Tersa

RequestLab is a simple, free, multi-platform tool designed for HTTP API development, debugging, and testing. Run and test your various HTTP requests against your endpoints and check the results. It is intended as a native alternative to programs like Postman, Thunder Client, Bruno, etc. for Apple devices. You can run RequestLab on your Mac, iPhone, iPad, and Vision Pro while enjoying the same functionality. Additionally, you have the convenience of sharing your requests between these devices using the import/export functionality. - Create and edit HTTP requests: GET, POST, HEAD, OPTIONS, DELETE, PUT, TRACE, CONNECT, PATCH - Supported authentication methods: Basic, Bearer - Import/Export from and to JSON format for sharing your request - No user tracking, no subscription, no login required. What happens on your device stays on your device.

Tersa is a touch-first workspace for learning, reviewing, and tuning small analog and RF circuits on iPhone and iPad. Build editable schematics, configure DC operating point, DC sweep, AC and transient analyses, and inspect measurements on clear plots. For linear two-port work, review S11, S12, S21 and S22, return and insertion loss, and raw complex data on a Smith chart. Use local sample projects to explore RC and LC filters. Change supported component values with the tuner and run the analysis again without rebuilding the project. Import supported SPICE model cards and subcircuits when a circuit needs them. Simulation runs locally on the device. Results depend on the circuit, models, and numerical settings and must be independently verified before fabrication or safety-related use.
