Grace Digital – Remote Control 4+

The 3.0.5 upgrade doesn't work the sleep timer on my Micro System. Problem may be the radio's firmware or maybe my iPad2s. The firmware shows up to date. The radio is only a year old.

OTOH, The ability to turn it on and off and control volume (make those volume buttons bigger, please) from the remote AND the extra presets make this a great app.

Update: my app works great with my Mondo and the Micro System I use as a tuner on my stereo. But I talked a friend into buying the Tuner and the app he downloaded only shows 10 presets while mine shows 23. Stations loaded via the app don't stay in the tuner. Grace says there's an issue and a new version will be out soon. I sure hope it doesn't override whatever I have running, though. I just don't understand why the current app only shows 10 presets, even in the photo here, since mine has 23.

The app works well controlling the radio and Pandora functions on my Mondo.
Like other reviewers, I wish it would let me control the USB menu. Kind of a nuisance having to get up to select USB songs at the radio. Not a deal-breaker, but would give the app 5 stars if allowed USB file selection.
BTW, the Mondo plays FLAC files recorded at 16-bit, 44.1 kHz. Some of the literature implies only 24-bit, 96 kHz is supported.
I sold my Logitech Squeezebox Radio after I got the Mondo. To compare the two -- the Mondo has much better sound quality using the line out to external amp/speakers. But, you can't control the Mondo's line out volume, again necessitating at walk to the amp to adjust volume. I guess a better amp would have volume remote control, but I'm driving two powered speakers with no remote. All-in-all, the Mondo is a superior product. The app would be perfect with a few tweaks.
I also wish Grace Digital had a Windows PC remote control or Internet remote.

May 2, 2016 I just found this Grace Radio App, downloaded it to my iPad(2) and it connected immediately with my Grace Radio (service pack V226-a-113a-613). What a relief! Trying to scroll around using the radio's dial system was tough, and doing it from the online website only allows me to add stations, etc. but not directly control the radio.

I can't (or haven't figured out how) to add to "My Stuff" yet using the app, BUT...I can control the radio with absolute ease...see all my presets...see all my "Stuff"...in short, LOVE IT.

I can view and add new "stations" to my Pandora account, thumb up and down tracks. Album covers show with each Pandora track being played.

This app allows me to see tracks being played via the radio's USB port, but the app does not yet display the USB menu, nor allow me to select USB tracks (have to use the radio dial system). If it did...killer...I'd have my 500+ CD collection at my fingertips.

I play my Grace radio almost all day because the quality of sound is outstanding when you preset HD streaming stations (like Linn, Pandora, etc), and, because I like lots of variety, it is very easy to change channels or search from the thousands available. This app makes it all come together. I have the radio ported via fiber-optic cable to my receiver for high quality sound. Very nice.
