NO Advertising, Math Simply is an easy-to-use calculator with a minimalist design that allows users to place the calculator on the Home Screen of their iOS or macOS device to perform calculations directly without opening the app itself. The widget calculator has an almost identical calculation experience to the main APP. Version 2.0.0 introduces a brand-new unit converter feature, offering conversions for over 100 units across 10 categories, with more content to be added in future updates. It has the following features: 1. Easy-to-use interface – has the same design interface as the traditional calculator, simple and clear. 2. Has almost the same widget calculation experience as the main program (the widget calculator only lacks the cache memory function). 3. Adopts the cache memory function and provides four cache operation buttons, which is convenient for diversified calculations. 4. User-friendly hints – hints for “Previous Result”, “current operator” and operation status during calculations. 5. Global Localization – Math Simply not only supports 12 languages, but also provides globalization support, whether you are used to using “.” or “,” as a decimal point, or “,” or “‘” as a thousands separator, Math Simply adapts to your needs in real time. 6. Personalization – For display modes, button vibration, button shapes and colors, and even display fonts, Math Simply offers adjustments to provide a variety of personalized settings. 7. Unit Converter - Quick and intuitive unit conversions, with customizable precision control. 8. Future Upgrades – Math Simply is a one-time purchase and download for life, with access to all future upgrades (including more convenient calculation features). Math Simply currently supports all iPhone and iPad devices with iOS 17 installed. In addition, thanks to the characteristics of the M series chips, Mac with Apple Silicon chips can also install this app and use the Widget Calculator function. In the near future, Math Simply will also add more convenient features, aiming to help users calculate more conveniently. Thank you for your support!

PommeCore is the full-featured companion app for MeshCore LoRa mesh radios — a decentralized, off-grid messaging network that works without internet, cell towers, or servers. Everything runs over long-range LoRa radio, directly between devices. MESSAGING Send and receive direct messages with real-time delivery tracking (Sending → Sent → Delivered, with round-trip time). Channel (group) messages broadcast to everyone on the mesh. Reactions and quoted replies are interoperable with MeshCore One. Undelivered messages retry automatically, then flood the mesh. CONTACTS & CHANNELS Organise contacts with favourites, nicknames, notes, and groups. Mute or block individuals. Each group and channel has its own notification mode and sound. Export and import contacts via QR code or meshcore:// URLs. MESH MAP See all contacts with GPS on an interactive map. Tap a pin to open that contact's chat. Enable position trails for movement history. The link quality overlay draws colour-coded lines (SNR) to contacts in range. RADIO SETTINGS & TOOLS Configure frequency, spreading factor, bandwidth, coding rate, and TX power from the app. Radio Stats, RF Monitor with Packet Log, Line of Sight analysis, Radio Calculator, Airtime Calculator, and Frequency Scanner are all included. BACKUP & UPDATES Export your radio configuration as a .meshprofile file. Firmware update checker alerts you when a new release is available. Over-the-air ESP32 firmware updates via WiFi. REMOTE MANAGEMENT Administer repeaters and room servers over the mesh — change names, frequencies, routing scope, and advert intervals without physical access. WIDGETS & WATCH Home screen and lock screen widgets show connection status, battery, and unread count. The watchOS companion lets you read and reply to DMs and channel messages from your wrist. iPHONE, iPAD & MAC One app runs natively on iPhone, iPad, and macOS (Apple Silicon and Intel). Connects via Bluetooth LE, WiFi, or USB serial on Mac. LANGUAGES English, German, French, Spanish, Italian, Dutch, Portuguese, Czech, Polish, Ukrainian, Japanese, Simplified Chinese. ACCESSIBILITY VoiceOver, Dynamic Type, Differentiate Without Color Alone, Dark Mode, Voice Control. PRIVACY No account required. No servers. No data collection. All communication is peer-to-peer over LoRa radio. iCloud sync for nicknames, notes, groups, and settings uses your private iCloud account. HARDWARE REQUIRED A MeshCore-compatible LoRa radio running Companion firmware is required. Recommended: Compatible Mesh radio with latest MeshCore Companion firmware IN-APP PURCHASES Tip Jar ($0.99–$9.99) — voluntary support, no functional gating.
