If you’ve landed on this search query, you are likely a fan of Team Cherry’s masterpiece, Hollow Knight . You own an iPhone or iPad, and you are looking for the holy grail: a free, downloadable IPA file that runs better than the standard version.

If you are developing your own app or using a legitimately obtained IPA, installing it requires sideloading, as Apple does not allow direct installation of apps outside the App Store. Common methods include:

→ play Hollow Knight fully legally on your iPhone for $0 (first month) or ~$1. No IPA needed, no piracy, no malware risk.
It is unlikely to happen soon. That is why the "free better IPA" remains a dream.

The installation process for TrollStore is more involved and depends on your specific iOS version, but numerous detailed guides are available online. Once installed, you can open the TrollStore app, tap the "+" sign, select an IPA file from your files, and it will be installed permanently.
