Best iOS Sideloading Tool for Brawl Stars Mods in 2026

5 min read

Choosing between iOS sideloading tools for a no-jailbreak Brawl Stars mod install comes down to one question: what signs the app for you, and how often does that signature expire? The tools below split into three real categories — free enterprise certificates, your own free Apple ID, and a paid developer certificate you buy or enroll for separately. In fact, the category matters more than the specific app name, since it decides whether you need a computer, whether it costs money, how often you’ll redo the install, and how likely the tool is to vanish overnight.

iOS Sideloading Tools: Quick Comparison Table

ToolSigning MethodNeeds a Computer?Needs Apple ID?Typical ExpiryReliability
ScarletFree enterprise certificateNoNoUnpredictable — revoked with no fixed scheduleLow; community sideloading guides list it as largely deprecated
ESign / KSignEnterprise cert, or a cert you supplyNo (enterprise mode)Only if using your own certSame unpredictable revokes in enterprise modeLow in enterprise mode, more stable with your own cert
FeatherA paid developer certificate you supply (Apple Developer Program, or a paid third-party provider)Only to generate the certificate itselfYes — a paid, enrolled Apple Developer Program account, not just a free Apple IDUp to 1 year, but locked to your device’s registered UDIDActively maintained and stable once set up, but the most expensive and technical option here to actually set up
AltStoreYour own Apple IDYes, for setup and periodic refreshYes7 days, auto-refreshed over Wi-Fi if your computer is reachableHigh; long-established and widely documented
SideStoreYour own Apple IDNo ongoing computer need after setupYes7 days, refreshed on-deviceHigh; newer AltStore fork that drops the computer dependency
SideloadlyYour own Apple IDYes (Windows or Mac)Yes7 daysHigh; simple drag-and-drop workflow
TrollStoreExploits an iOS signing bug directly — no certificate at allNoNoDoesn’t expire, but only works on iOS versions where the exploit is still openHigh where compatible; check your iOS version first

No Computer, No Apple ID: Scarlet and ESign/KSign

Scarlet and ESign/KSign both bake a free enterprise certificate straight into the app in their default mode, which is what makes them the fastest way to get a mod running with nothing but the phone in your hand. However, that same shortcut is exactly why they’re the least stable option: Apple treats leaked enterprise certificates as something to shut down, and revokes them with no announced schedule. Like most tools in this category, their download links move around over time, so confirm you’re on an actively maintained site before installing either one.

A Paid Certificate You Control: Feather

Feather doesn’t come with a built-in certificate — instead, you supply one, and its own official documentation only lists paid ways to get it: enroll in the Apple Developer Program (about $99/year) and generate a distribution certificate yourself, or buy one from a third-party provider like Signulous. Either path also means registering your specific device’s UDID, so the certificate only works on that device, and involves real setup — Keychain Access and the Apple Developer portal on the Apple Developer Program route, or a purchase-and-wait process (community reports mention roughly 72 hours) with Signulous.

That cost and effort buy real stability, though: a certificate under your own name doesn’t fall into the same mass-revocation waves that hit shared enterprise certificates like Scarlet’s, and typically lasts closer to a year rather than getting pulled with no warning. This is the option community sideloading guides point to once an enterprise-cert tool stops working — just budget for the setup, not a five-minute fix.

Your Own Apple ID: AltStore, SideStore & Sideloadly

These three all sign apps with your own free Apple ID, which caps you at a handful of sideloaded apps at once and a 7-day expiry — but that expiry is predictable, not a surprise. AltStore and Sideloadly need a Windows or Mac computer for the initial setup, and AltStore can auto-refresh the install over Wi-Fi as long as your computer stays reachable. SideStore, meanwhile, is a newer AltStore fork that drops that ongoing computer dependency after setup. Overall, all three hold up far more reliably long-term than an enterprise-certificate tool, at the cost of a more involved first-time setup.

The Exception: TrollStore

TrollStore doesn’t use a certificate at all — instead, it exploits a signing bug in specific iOS versions, so an app you install through it doesn’t expire the way every certificate-based option above does. The catch is compatibility: it only works on the iOS version ranges where that bug is still open, so check your exact iOS version before assuming it’s an option.

Which iOS Sideloading Tool Should You Actually Use?

Among iOS sideloading tools, there’s no single winner — only the right trade-off for your situation. If you don’t have a computer handy and just want the mod running today, Scarlet or ESign/KSign is still the fastest path — just accept that you’ll likely reinstall it every so often when Apple revokes the certificate. Otherwise, if you have a Windows or Mac computer available even just once, AltStore, SideStore, or Sideloadly trade a bit of upfront setup for a predictable weekly refresh instead of a surprise outage, at no cost. Feather sits apart from both: no computer is required day-to-day once it’s set up, but getting there means paying for a certificate and registering your device — worth it mainly if you specifically want a certificate that lasts close to a year instead of a week.
