Good App! very helpfull But there are some problem 1) if u have dual sim phone, it will tell you that message has successfully sent but message will not b sent. although SIM settings are perfect in mobile to send SMS from specific sim 2) message success msg browser tab sould be closed auto in specified time like 3 or 5 seconds. some javascript will easily do this. Kindly consider above & solve these to polish experience. Great App!

Good App but I have a problem! I have successfully installed your application along with its tool but my Android is not sending the messages and when I check in default messages app, I see my message (that I has sent through your URL) but default messages app is showing โ€œNot sent. Tap to try againโ€.

You need helper tool for it

Whatโ€™s new

- smoother Home screen: Main content scrolls when it doesnโ€™t fit on small displays.

- Consistent UI scale: Shared app_* dimensions across screens (phones, tablets with a centered max width, landscape tweaks) for aligned padding, type, and control sizes.

- Gradle: Updated Groovy DSL to recommended property = value style; optional HTML problems report disabled via gradle.properties to reduce noisy console output.
