    IOS6 and recent iTunes updates have broken a few features. We have made some partial fixes, but they are not complete. If you'd like to help support our development, or take over the development please let us know. Explore the internal file structure of your iphone (or of a seized phone in the case of forensic teams) using either the iphone's own backup files or (for jail broken iphones) ssh. Viewing of plist, sqlite, and hex are supported. IOS 5 is now supported iOS 6 only partially works at the moment (some features fail or are missing). Unfortunately paid work means we can't fix this right now, but would welcome anyone else submitting patches.

    OpenRemote

    OpenRemote

    Open Source for Internet of Things

    An Open Community in the Home Automation and Domotics space. We believe an Open Source approach can revolutionize the way people create, install, and maintain software in the industry. Our panel technology integrates with your favorite protocol and runtime hardware through Open Source software. We open up the front-end and support a unified panel and visual programming model. An installer can pick and choose hardware products from different vendors and still present one panel UI to the user. A proprietary hardware vendor can build modern panel support and integrate with existing vendors. Whether you are a DIY aficionado, a high-end installer, a hardware vendor or integrator, OpenRemote has something for you. We want to make OpenRemote the standard for commercial and hobbyist integration alike. We allow any integrator or vendor to write plug-ins and bring innovative tools that simplify the work of an installer and the relationship with the client.

    DotNetOpenServer SDK

    DotNetOpenServer SDK

    Lightweight fully extendable client/server application framework

    DotNetOpenServer SDK is an open source lightweight fully extendable TCP socket client/server application framework enabling developers to create highly efficient, fast, secure and robust cloud based smart mobile device and desktop applications. Why? Unlike most application server frameworks, which are implemented over slow inefficient stateless protocols such as HTTP, REST and SOAP that use bulky ASCII data formats such as JSON and XML, DotNetOpenServer has been built from the ground up with highly efficient stateful binary protocols.

    MMKV for Android

    MMKV for Android

    An efficient, small mobile key-value storage framework

    MMKV for Android is an efficient, small mobile key-value storage framework developed by WeChat. Works on Android, iOS, macOS, Windows, and POSIX. Efficient. MMKV uses mmap to keep memory synced with file, and protobuf to encode/decode values, making the most of Android to achieve best performance. MMKV supports concurrent read-read and read-write access between processes. Easy-to-use. You can use MMKV as you go. All changes are saved immediately, no sync, no apply calls needed. MMKV contains process locks, encode/decode helpers and mmap logics and nothing more. It's really tidy. MMKV adds about 50K per architecture on App size, and much less when zipped (apk). MMKV is published under the BSD 3-Clause license. Starting from v1.2.8, MMKV has been migrated to Maven Central. Older versions (<= v1.2.7) are still available on JCenter.
