Modding a single-player, paid game you already own (e.g., removing ads) is arguably ethical. Modding a free-to-play multiplayer game to steal virtual currency harms developers and other players by breaking the economy. Most modding forums ban "online hacks" for competitive games to avoid server-side bans and toxicity.
Apple’s iOS 9+ requires valid code signatures for every executable and resource. Since you broke the original signature, you must re-sign.
You cannot modify an encrypted IPA. To decrypt, you need a jailbroken iOS device.

A modded IPA freezes the app at a specific version. When the official app updates (e.g., critical security patch or new content), you cannot install the update without losing the mod. You must wait for the repack group to release a new version.
Decrypter (Optional):
Modify the App:
Re-sign the App:
Repack into IPA:
