Of course, anybody can send a text message via e-mail, but you have to know the recipient's carrier and proper format for the address. SMS Touch takes the guesswork out of it: You just choose a recipient from your address book and the app handles the routing. Any replies you receive land in your e-mail inbox -- not quite as convenient as traditional SMS, but at least you don't get charged.
As an added perk, SMS Touch works in landscape mode, giving you a comfier widescreen keyboard on which to tap-type. Not bad for a one-time charge of $4.99. I'm a light texter, so I can get by on my 200-per-month allowance, but heavy texters can save big with this app -- and maybe even drop down to a less-expensive SMS plan as a result. [via Gizmodo]
