App Cloner for iPhone: 6 Ways to Clone Apps and Run Multiple Accounts

Why iPhone has no built-in app cloner

On Android, cloning an app is often a setting. Samsung Galaxy phones have Dual Messenger, which adds a second copy of supported messaging apps, and parallel-space style apps run a second copy of an app inside themselves. iPhone has neither. The App Store won't install the same app twice, and iOS doesn't let one app run another iPhone app inside it.

So on iPhone, “clone apps” comes down to two ideas: more accounts inside one app, which is what account switching does, or a separately installed copy of the app with its own app ID, which is what sideloading, TrollStore and device-signed clones do in different ways. A second phone and web versions sidestep the question by giving you another screen instead.

Most people looking for an app cloner aren't after one spare account. Sellers, support teams, social media managers and agencies often run five, ten or fifty accounts of the same app and want them all signed in all day. Two accounts is the minimum worth comparing, not the ceiling. For a broader introduction, see our guide to clone apps on iPhone.

The 6 methods at a glance

Here's how the six methods compare on the points that matter most when you run several accounts every day.

What each method does and doesn't do

Account switching in the app. Many apps let you add accounts and switch between them for free: Instagram holds up to 5, Telegram 3 (4 with Telegram Premium), and WhatsApp on iPhone 2 since June 2026. It's official and costs nothing, but the cap is low and only one account is open at a time. Some apps have no switching at all: LINE is one account per phone and per phone number.

A second phone. Simple, and the accounts are fully apart. It also costs a device, often a SIM or number too, and it's one more thing to carry and charge. That works for one spare account and gets heavy at five or ten.

Web and desktop versions. WhatsApp Web, Instagram in a browser and similar versions let you use an account without installing the app again. Features are limited, you get one account per browser session, and it isn't the full app experience on your phone.

Sideloading with a free Apple ID. Tools such as AltStore and Sideloadly install apps that you sign yourself with an Apple ID. It's free, but it needs a computer, apps expire after 7 days and must be re-signed, and Apple limits a free account to 3 sideloaded apps at a time. It suits someone with a computer nearby and one or two extra apps.

TrollStore. Installs apps permanently, with no re-signing. It only works on certain older iOS versions, though; current iOS versions aren't supported, so it's an option only if your iPhone is on one of those versions.

Device-signed clones (iClone). iClone signs copies of an app for your iPhone's device ID, each with its own app ID and its own data container, and you install them from Safari on that iPhone, with no computer and no jailbreak. Up to 50 copies of one app stay signed in at the same time, each to its own account, next to the official App Store app. You pay for a fixed term that doesn't renew automatically, and during it you get compatible updates, reinstalls and support. Each account still needs its own phone number or sign-up details.

Which method fits you

The right choice depends less on the app than on how many accounts you run and how often you need them.

• One spare account you check now and then: use the app's own account switching. It's free and official, and a quick switch is no hardship once or twice a day.
• You're at a computer most of the day: web and desktop versions are handy for one extra account per browser session alongside your phone.
• You have a computer and don't mind upkeep: free Apple ID sideloading covers up to 3 apps, as long as you re-sign them every 7 days.
• Your iPhone is on an older iOS version that TrollStore supports: you get permanent installs, but it isn't an option on current iOS versions.
• A personal number and a work number, both signed in: one extra copy does it. For WhatsApp, LINE, KakaoTalk and some other apps, iClone's Dual install adds one copy with its own name and icon on an annual plan.
• A shop, support desk or agency running 5, 20 or 50 accounts of one app: device-signed copies keep them all signed in on one iPhone, without weekly re-signing or a drawer of phones. See the WhatsApp and Instagram plans, or our guides to multiple WhatsApp accounts and multiple Instagram accounts on iPhone.

What to check before paying any signing service

Paid signing services work in different ways. Before you pay anyone, us included, check these points:

• How the apps are signed. Some services sign with enterprise or shared certificates. Apple can revoke a certificate, and when it does, the apps signed with it stop opening. Ask what happens to your apps and the rest of your term if that happens.
• Whether the copies are tied to your device. Device-specific signing reads your iPhone's device ID (UDID) first and signs the copies for that phone. iClone works this way: Safari installs a one-time profile so the site can read the UDID.
• Whether it renews automatically. Some services bill on a subscription. iClone sells fixed terms that don't renew automatically.
• Refunds and support. Read the refund terms before you pay, and make sure there's a real way to reach someone if an install fails or a copy stops opening. iClone's is on the support page.
• Reinstalls and updates. Find out whether you can reinstall after deleting an app or resetting the phone, and whether compatible updates are included during the term.
• What it asks for. Signing for your phone needs its device ID, not your Apple ID password or your app passwords. iClone asks for neither; you sign in inside each copy yourself.
• What nobody can promise. Every account follows its app's own terms, and whether an account is restricted is the app provider's decision. Each copy keeps its own data on the phone, but the provider can still link accounts on its own servers.

How to set up device-signed clones from Safari

If device-signed copies fit your setup, here's how iClone works. Everything happens in Safari on the iPhone that will run the copies, and the App Store version of the app stays installed and keeps working.

1. 01

   On that iPhone, open the app's page in Safari, for example WhatsApp or Instagram.

2. 02

   Choose a plan and a term. Multi-clone puts up to 50 copies of the app on one iPhone; for some apps, Dual install adds one extra copy with its own name and icon.

3. 03

   Install the one-time profile when prompted so the site can read your iPhone's device ID (UDID), then pay.

4. 04

   Watch the signing progress on your order page and, when it's done, install the copies by following the instructions shown there.

5. 05

   Open each copy and sign in to a different account. Add copies as your team or your markets grow.
