Can someone post a nice concise summary of SSTV aps available for smart
phones and tablets that would let people see the SSTV from the ISS this
coming week with nothing more than an HT and a phone?

This can be the seed for all hams to have such an AP so that when they
witness something and are beyond cell service, they can snap a pix, and send
if via their HT o r mobile, and similarly receive such remote area images
too over Ham radio.

The technology is here.  Kenwood did the VCH1 Handheld SSTV system back in
the 90's but it was hardware specific and before its time.  Now, EVERYONE
has the SSTV processing power in their pocket to make ham radio imaging
possible anytime anywhere.  Let's start practicing our ability to use it.

ARISS Russia is planning a special Slow Scan Television (SSTV) event from
the ISS in celebration of Cosmonautics Day. Transmissions begin April 11 at
11:30 UTC through April 14 at 18:20 UTC on 145.800 MHz using the PD-120 SSTV
mode.

A Russian computer on the ISS, stores images that are then transmitted to
Earth using the onboard Kenwood TM-D710E transceiver.  Images will be from
the Interkosmos project period of the Soviet space program
(https://en.wikipedia.org/wiki/Interkosmos).

Images received can be posted and viewed at
