The whole toolchain fits in your pocket.

No desktop app, no USB, no weekly trip to a computer. Every step runs on the phone.

Sign & install

Any IPA, in a few taps

Free Apple ID or your own certificate. Tetherless signs it, sends it to your Home Screen, and keeps it alive with one-tap resign — Unsigned → Signed → Installed.

01
Decrypt

Clean copy of apps you own

Download from the App Store and make a DRM-free copy — fully on-device.

02
Custom cert

Over-the-air install

Bring your own paid certificate. No pairing, no VPN.

03

Tweak injection

Add .deb / .dylib tweaks while signing.

Keep alive

Resign before a signature expires.

Built-in Files

Manage everything in-app.

Set up in minutes.

No computer, start to finish — from a fresh iPhone to an app on your Home Screen.

Before you start
An iPhone on iOS 17.4+

With a passcode set. iOS 26 or newer runs Modern; 17.4–25 runs Legacy.

A Wi-Fi connection

Signing and installing need Wi-Fi — mobile data alone won't do it.

A free Apple ID, or your cert

Sign with a free Apple ID, or bring your own paid certificate.

A way to install it once

Any sideloading tool gets Tetherless on the first time. We recommend iPASide.

1

Get Tetherless on your iPhone

Download the build that matches your iOS — Modern for iOS 26+, Legacy for 17.4–25 — then install it once with any sideloading tool.

Recommended

iPASide — installs Tetherless, and can also create the pairing file you may need in step 3.

Also works

AltStore, SideStore, eSign or KSign — anything that can install an IPA.

2

Pick how you sign

Choose one — you can switch later in Settings.

Free · Apple ID

Sign in with a free Apple ID in Settings. Apps stay valid 7 days; one tap resigns them. Needs a one-time pairing — step 3.

Your certificate

Import your .p12 and .mobileprovision in Settings. Installs over the air — no pairing, no VPN. Skip step 3.

3

Pair your iPhone Apple ID only · one time

Install the free LocalDevVPN app from the App Store, open it once, and tap Connect. Then, in the Pair tab:

iOS 27

Tap Start Pairing, then on this iPhone open Settings → Privacy & Security → Developer Mode → “Pair with…” and enter the code Tetherless shows.

iOS 17.4–26

Import a pairing file instead — make one with iPASide (or iloader) and import it from the Pair tab.

4

Add an app

In the Library tab, tap + to import an IPA. Or open Decrypt to pull a clean, DRM-free copy of an app you already own — straight from the App Store, on-device.

5

Sign & install

Open the app in Library, tap Sign, then Install — it lands on your Home Screen. Tap Resign anytime to keep it from expiring; Tetherless keeps itself signed, too.

Questions.

Do I ever need a computer?
No. Only the very first install uses a sideloading tool of your choice. After that, everything — signing, installing, resigning, decrypting, even updating Tetherless — happens on the iPhone.
How long do installed apps last?
With a free Apple ID, 7 days — open Tetherless and tap Resign to renew. A paid certificate lasts a year. Tetherless resigns itself too, so it won't fall off your Home Screen.
Modern or Legacy — which do I pick?
On iOS 26 or newer, pick Modern. On iOS 17.4–25, pick Legacy. Same features either way; Modern just uses the newest system look and on-device pairing.
Why does free signing need LocalDevVPN and pairing?
Free Apple-ID installs go through an on-device connection. LocalDevVPN provides that connection, and pairing authorizes this iPhone once. Bring your own certificate and you skip both — it installs over the air.
Is this allowed?
Only install apps you own or have the right to use. Tetherless isn't affiliated with Apple; “iPhone”, “iOS” and “App Store” are trademarks of Apple Inc.
