How can iOS users sideload a modded app safely?

I’m trying to install a modded game on iOS and want a reliable sideloading method that doesn’t require another device. I’ve read about tools like Scarlet, Sideloadly, AltStore, and using a paid UDID certificate.

What’s the safest and most straightforward way to sideload a modded app, including steps for enabling Developer Mode, setting up certificates, and signing the .ipa file?

Are there any risks I should be aware of when using these methods?

I’ve sideloaded apps on my iPhone before, and AltStore is my go-to because it’s completely free and works without jailbreaking.

How it works:

You install AltStore on your iPhone via your PC/Mac, then you can sign and install .ipa files directly.

Steps I follow:

  • Install AltServer on your computer and connect your iPhone.

  • Enable Developer Mode on the iPhone (Settings → Privacy & Security → Developer Mode).

  • Open AltStore on your device, then sideload the .ipa file.

  • Pros: Free, relatively safe, no additional device needed.

  • Cons: Apps need to be refreshed every 7 days unless you have a paid Apple Developer account.

I personally use it for testing modded apps or betas, and it’s worked smoothly for me.

Another option I’ve used is Sideloadly, which lets you sideload .ipa files using either a free Apple ID or a paid developer certificate.

  • Pros: Works with free Apple IDs, supports multiple devices, gives more signing options than AltStore.

  • Cons: Free Apple ID limits you to 3 active apps and 7-day certificates. Paid certificates remove this limitation but cost $99/year.

Steps:

  • Download Sideloadly on PC/Mac.

  • Connect your iPhone and enable Developer Mode.

  • Enter Apple ID credentials (or paid certificate) and select the .ipa.

  • Click Start to sign and install.

I like this when AltStore fails to install certain .ipas, or if I need to sideload multiple apps quickly.

Since you’re sideloading modded apps, there are some important things I’ve learned the hard way:

  • Use trusted sources only – don’t grab .ipas from sketchy websites; you risk malware or phishing.

  • Sandbox testing – I usually test modded apps on a secondary Apple ID or device to avoid account issues.

  • Certificates matter – Free Apple ID certificates expire every 7 days. Paid developer certificates reduce hassle but are not free.

  • Stay in Developer Mode – Sideloading won’t work if your device isn’t in Developer Mode.

Honestly, for most casual users, AltStore + a free Apple ID is the safest and simplest method.

If you’re okay spending a bit, Sideloadly with a paid developer certificate is more stable and long-term.
