On your ANDROID device go to "Lock screen and security" and turn ON "Unknown sources Allow installation of apps from sources other than the Play Store"
Download attached VoteCueto.apk to your device (below and click on the down arrow button ------------>)
The first time you run it will ask for permission so set "Texts to Send to 1" then hit GO (Cueto's face).
After that you can change the 1 to a larger number, start smallish and see how it works.
e-mail me if it crashes, email@example.com
** I think Android has a limit of texts an app can send per hour, perhaps 100/hr or 50/30min.
