AMPKIT
Even when utilizing a full recording setup with your chosen DAW, finding a suitable amp simulator might be hit or miss. AmpKit, on the other hand, is a fantastic program for guitarists who don't have access to a DAW or simply want to play at home with their headphones. AmpKit crams a lot into one program, with 30 guitar amps and 30 pedals (all based on genuine models).
To connect your guitar to your device, you'll need an adapter, but for a little expenditure, you'll be able to record on the move and upload your sessions to Dropbox. This is an excellent way to get your riffs and song ideas to your band before practices. AmpKit is presently available for free on the App Store, albeit you need an adaptor to use it.
