Hey Action

Features
Read full description

Your web request is now a button. Already have a webhook or a working HTTP request? Make it a button you can use every day. Hey Action keeps the request you need in front of you, without a full API testing workspace. Save one complete action and run it for free. A one-time Pro purchase unlocks unlimited saved actions. SET UP ONCE Enter your request manually, preview a supported cURL command on your device, or try the clearly labeled public example. Importing and saving do not send a request. Test Request and RUN send real requests to your endpoint. RUN IN ONE TAP Choose your saved action with the wheel, then press the large RUN button. Selecting an action does not send a request. Use Edit when you want to change the request. Your everyday action stays front and center, with request details out of the way. Tap the information control beside the request summary to see the full selected action name without running it. Find saved actions by name in a separate list, arrange them in the order you prefer, and remove actions you no longer need. Your main screen stays simple. KNOW WHAT HAPPENED See success or failure, HTTP status, response time, a short response preview when available, and a practical next step for common connection, authentication, request, and server errors. The last main RUN summary remains after reopening the app. It covers the main RUN button, not editor tests or other execution entry points. Response previews are not saved in this history. GO ADVANCED WHEN YOU NEED IT Set the URL, method, headers, and raw request body in the Action Editor. cURL import fills supported fields after an on-device preview. Unsupported options are explained rather than silently ignored. If import fails, keep the original command visible while entering the request manually. โ€ข GET, POST, PUT, PATCH, DELETE โ€ข Up to 20 custom headers per action โ€ข Raw request bodies for supported methods (GET bodies are not supported) โ€ข On-device import of supported cURL commands โ€ข Clear, categorized results HEY ACTION PRO One saved action includes the complete editor and unlimited runs. A one-time Pro purchase unlocks unlimited saved actions, so you can keep multiple requests ready and switch without entering them again. No subscription. All users, including existing users, can use one action for free. Existing saved actions are not deleted. Choose which action to use for free, or unlock Pro to use all saved actions. Restore Purchases is available from the action list and the Pro screen. Restoring Pro restores your purchase, not deleted action configurations. PRIVATE BY DESIGN No account is required. Action names, URLs, query values, header values, request bodies, response bodies, tokens and API keys are not included in usage analytics. Saved action configuration is stored on the device; executing a request sends it to the endpoint you configured. HELP WHEN YOU NEED IT Open Help & Support from your action list, or contact snj830526@gmail.com. Result notifications are optional for actions run with the main RUN button and require iOS permission. App Settings in the action list contains the global notification preference and permission guidance.

Reactive Playground

Features
Read full description

Reactive Playground is a visual learning app for reactive programming. Instead of reading operator definitions only, you can play with marble timelines directly. Pick a category, open an operator, move events around, edit their values, clone items, remove them, or turn them into errors and completed events. The output updates live so you can understand what each operator really does. Explore operator categories such as: Transforming Filtering Combining Error Handling Utility Each playground shows a source timeline, an output timeline, a short explanation, and a code-style example. It is useful for learning ReactiveX concepts, reviewing operators, or quickly refreshing how a stream behaves before using it in code. Reactive Playground is made for developers, students, and anyone learning Rx-style reactive programming.
