Spam is reaching out to you via SMS in a big way owing to the fact that it is much cheaper and practically is just a fraction of voice spam.
The app, smsblocker checks for 6000 spam cases and detects the spam automatically (no alerts) and one can define filters (for instance,sms alerts from your bank account) etc.
The app (currently works on Nokia, Sony and Samsung phone) costs $2 (INR 99/), and the startup is giving away the app for free till June 28th.
Do give the app a spin and share your feedback.
Note to Optinno team: the more brands you create, the more is your marketing cost. Think about it.
