Not really - Digitrax just released a new handheld. TCS released two handhelds in as many years. NCE has done nothing. I use Roco and they have wifi remotes. Neither Digitrax, EasyDCC, nor NCE have migrated to smart phones. Digitrax offers "JMRI in a box" via its LNWI product.

Hybrid.... the ESU Cab Control remote:
it’s an android device in a custom box. I’m a fan. It’s easy to update, easy to use, tedious but easy to configure the functions, has a knob and 4 buttons that can be programmed to whatever function you want. The knob has motorized rezero and going past 0 changes the direction. Holds more engines than any one person can own... oh, and it talks to the cab control base via Wifi.
I like what the TCS UWT100 can do, but it needs a bunch of stuff to talk to the ESU base and I’m just not there yet.
900 MHZ is dead. I don’t even think you can get a cordless phone in that band anymore. If you want a new remote, get with the times and campaign the new Electronics company to build a wifi remote with a thumb wheel.
