SPI is an SMS application that complements the one provided in Android. SPI allows secure sending and receiving SMS to selected contacts. The data is encrypted and stored in the memory card, making it impossible to read, even with a computer.
SPI includes a secret inbox and outbox , only accessible by the user via a password of his choice. The receiving messages notification text is composed by the user. He can also decide not to be notified at all, making reception of SMS totally invisible for the selected contacts. This fantastic function keeps you relax even when the phone falls into the wrong hands (some top athletes would have paid a fortune to use SPI ...).
The user can continue using his normal SMS Android application for sending messages to contacts stored in SPI. Only the sending/receiving SMS treated in SPI remain secret and invisible.
At first launch, SPI takes you by the hand to configure SPI and add your selected contacts. SPI integrates usual features of SMS applications and is extremely user friendly.
The free demo version SPI Lite is limited to 1 contact and 5 messages.
