How to Schedule WhatsApp Messages with SKEDit

Go to Google Play Store and download and install an app called "SKEDit". Make an account in this.
The SKEDit main screen will get displayed with many options; here you need to choose WhatsApp.
One you choose WhatsApp, you need to grant the "Accessibility" permission to the app.
Now you can enter the receiver's contact number, your message and schedule the date and time to share it.
If you enable the "Ask me before sending" option, the app will notify you before sharing the message.
If you do not enable the "Ask me before sending" option, your message will be shared on the scheduled time without notifying you.
Under the notification, you will find three options where you need to select the "SEND" option. Once you do this, the message will be sent.
