I have heard from someone that uses both on a weekly basis that they prefer the supertrickler over the V4 for large grain powders, however the difference is minimal. Longterm product support is a question for both. Anything that depends on an app to function can be an issue if app development stops and you have to keep an old phone just to use the device. The supertrickler is a self contained system that should only be subject to an internal part failure. I am leaning towards the supertrickler as a self contained product just because app doesn't seem to provide additional function to offset the risk.
