Free tools is good for indies and kickstarter, Many of services become free to try out which is great. I accidentally run into this push notification service https://pushwizard.com/
I will do "in deep" review for this API like usual (they kind enough to let me try (some of) their API), and that should take some (of my free) time.
BTW, anyone want an Free ANE for this one? Please leave comment below more than 10 requests should be enough for headache ;)
PS : like always, anyone got alternate competitive Push Notification Service please leave comment below (even DIY solution is welcome, I'm always seeking for the best) I will take a look and try compare pros and cons here.
Happy Coding :)
UPDATE : Even more free service as BaaS!
