SideStore
SideStore is a fork of AltStore that doesn't require an AltServer
SideStore is an untethered, community-driven alternative app store for non-jailbroken iOS devices. SideStore is an iOS application that allows you to sideload apps onto your iOS device with just your Apple ID. SideStore resigns apps with your personal development certificate and then uses a specially designed VPN in order to trick iOS into installing them. SideStore will periodically "refresh" your apps in the background, to keep their normal 7-day development period from expiring. SideStore's goal is to provide an untethered sideloading experience. It's a community-driven fork of AltStore, and has already implemented some of the community's most-requested features. SideStore is a just regular, sandboxed iOS application. The AltStore app target contains the vast majority of SideStore's functionality, including all the logic for downloading and updating apps through SideStore. SideStore makes heavy use of standard iOS frameworks and technologies most iOS developers are familiar with. -

Proton VPN for iOS and macOS
Official ProtonVPN iOS and macOS app
The ProtonVPN iOS and macOS project contains the official code for the unified VPN client used on Apple platforms, delivering secure, encrypted network connections to Proton’s global servers directly from iPhones, iPads, and Macs. Written primarily in Swift with Apple platform conventions, this client lets users authenticate with their Proton accounts, select server locations, and manage advanced privacy features like automatic reconnection and DNS leak protection, tailored for Apple’s networking APIs. Because iOS and macOS have strict networking and extension models, the app uses system VPN configurations and integrates with native controls for background operation, seamless switching, and efficient battery usage. It supports both free and premium tiers of ProtonVPN, offering users flexible connection options while preserving Proton’s strict no-logs privacy policies. -

EeveeSpotify
A tweak to enhance Spotify experience
EeveeSpotifyReborn is an unofficial modification for the Spotify mobile application that alters client-side behavior to unlock premium-like features without requiring a paid subscription. It operates by injecting changes into the Spotify app, making it interpret the user account as having premium access and enabling functionalities that are normally restricted. The project was developed through reverse engineering techniques, including analyzing application behavior and intercepting requests to replicate premium functionality within the client environment. It also extends the base experience by adding features such as alternative lyric providers, enabling more flexible and enhanced lyric display compared to the default implementation. The tool requires users to build or sideload a modified application package, as distribution of prebuilt binaries is restricted due to legal concerns. -

UTM
Virtual machines for iOS and macOS
UTM is a full-featured system emulator and virtual machine host for iOS and macOS. It is based off of QEMU. In short, it allows you to run Windows, Linux, and more on your Mac, iPhone, and iPad. UTM/QEMU requires dynamic code generation (JIT) for maximum performance. JIT on iOS devices requires either a jailbroken device or one of the various workarounds found for specific versions of iOS. UTM SE ("slow edition") uses a threaded interpreter which performs better than a traditional interpreter but still slower than JIT. This technique is similar to what iSH does for dynamic execution. As a result, UTM SE does not require jailbreaking or any JIT workarounds and can be sideloaded as a regular app. -

AltStore
AltStore is an alternative app store for non-jailbroken iOS devices
AltStore is an alternative app distribution system for iOS that works without a jailbreak by using your own Apple ID to sideload and periodically re-sign apps. It pairs with a companion desktop app, AltServer, running on macOS or Windows, which handles signing and pushing apps to your device over Wi-Fi or USB. Once installed, AltStore can refresh app signatures automatically, keeping them usable beyond the standard seven-day limit that applies to free developer profiles. Users can install featured apps as well as add third-party “sources,” enabling a wider ecosystem of utilities, emulators, and experimental tools that aren’t available through the official App Store. The design emphasizes safety and transparency: apps are signed with your credentials, you can see what’s installed and when it will expire, and you control which sources you trust. -

FineTune
FineTune, a macOS menu bar app to control volume for each app
FineTune is a macOS menu bar application that gives users fine-grained control over system audio by allowing them to adjust volume levels for individual applications independently, route audio streams to different output devices, and apply personalized equalizer settings. It fills a gap in macOS audio control by providing more advanced routing and audio shaping capabilities than the default system controls, making it useful for power users, audio professionals, and anyone needing precise management of their sound environment. Through a clean, minimal interface accessible from the menu bar, FineTune lets users isolate and balance application volumes, assign specific outputs (like headphones versus speakers), and tweak equalization to enhance or tailor audio based on content or personal preference. Its integration into the OS workflow means that these adjustments persist across sessions and respect the user’s choices without requiring constant interaction with deeper system settings. -
