Text Scratch Pad PWA app Google Play Submission; 12 testers reached but need engagement for 14 days; New testers welcome

Last updated on 29 July 2026 Quick Info About Text Scratch Pad PWA app including its Netlify live app link As most Android users would want to install the PWA app via Google Play Store, I created a TWA (Trusted Web Activity) Android bundle using PWABuilder and submitted it to Google Play Console. As on 28 July 2026, 11.50 AM, the Text Scratch Pad  Closed Testing (CT) app on Google Play had "at least 12 testers opted-in". But 14 day period engagement is needed to meet the mandatory for recent Play Console developers like me, 14 day period of testing with 12 testers. So new testers are very welcome to contribute. Note that I used Testers Community app to help reach 11 testers but it was stuck at 11 testers and so I put up this post on 27 July 2026. Another '12 Testers' app helped me get to 12 and perhaps slightly more testers. If you would like to contribute to testing and help app get to Google 'production' review and hopefully, publication stage, you need to ...

Conveniently Drafting Long Messages on Mobile for Small Input Box Apps: Introducing Text Scratch Pad PWA

Image
Last updated on 23 Jul 2026 Text Scratch Pad is a minimalist, fast, and offline-first Progressive Web App (PWA) designed primarily for drafting messages on mobile.  [On PC desktop/laptop, to open pic in larger resolution (if available), right-click on pic followed by open link (NOT image) in new tab/window. In new tab/window you may have to click on pic to zoom in.] Dictating or typing a long message directly inside WhatsApp or a mobile AI assistant like Gemini can be problematic. The input boxes are cramped, the message can get easily sent by mistake before it is ready to be sent, and so quite inconvenient when you want to write or dictate a message that takes up more than a few lines. Text Scratch Pad provides a dedicated, distraction-free, large canvas. It acts as a clean "staging ground" for your text. You open it quickly, type or dictate comfortably using your device's native capabilities, copy your finished draft with a single tap, and paste it wherever you need ...

Using WebSocket, Service Worker, Push and Background Sync Advanced Web APIs in a Plain JavaScript Tutorial Echo Chat Client App

Recently, through a tutorial echo chat client app I developed, I was pleasantly surprised to experience the features of advanced web API of WebSockets, Service Workers & IndexedDB, Background Sync API and Web Push API available in Chromium based browsers like Chrome and Edge. Note that these features are provided directly by the browser and accessible via plain HTML and JavaScript. We do not need external libraries and frameworks to access them. The advanced web API features mentioned above, with the exception of WebSockets, are considered to be part of Progressive Web Apps (PWAs). I need to mention here that I got back to industry-level software development in 2024 after a gap of over 20 years and my first very limited exposure to developing a minimal PWA app with PWA functionality provided by default by Create React App tool, was in March 2024. Details So when I developed this tutorial echo chat client app, I was quite astonished to see how many device platform capabilities we...
