Can I use Deplike with any electric guitar?

Yes, and the main requirement is a standard 1/4-inch cable. That makes setup pretty direct for most electric guitars.

Does the app work offline without an internet connection?

Yes. The amp and pedal models are stored locally, so you can keep playing without internet access. That makes it useful for rehearsals on the road or anywhere you don’t want to depend on a connection. Simple, and that’s the point.

How many presets can I create within the app?

The source doesn’t give a preset limit, so I can’t claim a number here. What matters is that you can save and load custom presets, then organize them by the tones you use most, like clean, crunch, or lead.

Is there a way to update the amp models after purchase?

Yes, updates come through the app’s built-in update system. New models may be added over time, which helps keep the tone library fresh and closer to current playing needs. That said, the update timing isn’t spelled out in the source.
