Normally you should simply buy the app from Google Play as described above.

If that somehow isn’t possible you can buy the app either here using PayPal (with a PayPal account or a credit card) or you can buy it from Amazon. To buy it directly using PayPal just click on this button. After completing the purchase you will receive an email with a link to download the app:


You can also buy the CalenGooSMS add-on here, which can be used to automatically send SMS messages with CalenGoo.


To try CalenGooSMS for free you can download it here. However it will append "Sent with CalenGoo" to each SMS until you purchase it.

Or you can buy CalenGoo from Amazon instead which can be useful e.g. if you have a Kindle Fire and an Android phone:
