Mac

Your Mac doesn't tell you when WiFi drops. SignalDrop does. Instant alerts, signal warnings, A-F quality grades, and ISP-ready outage receipts. macOS doesn't tell you when your WiFi disconnects. The icon goes from full bars to empty bars and hopes you notice. You find out minutes later when your video call freezes, your terminal hangs, or your upload fails. SignalDrop fixes that. It's a lightweight Mac menu bar app that monitors your WiFi in real time and sends an instant macOS notification the moment your connection changes. Disconnect, reconnect, signal degradation, network switches — you'll know immediately, with the exact downtime when service returns. WHAT IT DOES: • Instant disconnect and reconnect notifications with exact downtime duration • Signal-weakness warnings before your connection drops (–75 dBm threshold with hysteresis to avoid notification spam) • "Connected but no internet" detection — catches dead networks that look online but aren't • SSID change alerts when your Mac silently switches networks • Connection quality grade (A through F) based on 24-hour stability • Per-network reliability tracking with uptime percentages and disconnect counts • ISP-ready troubleshooting receipt — one-click copy of a paste-ready outage timeline you can send to your ISP support chat • Event log with CSV export for sharing with your internet provider • Daily stats showing total disconnects and downtime at a glance • Launch at login — set it and forget it HOW IT WORKS: SignalDrop uses Apple's CoreWLAN framework for event-driven monitoring. Unlike tools that poll every few seconds, SignalDrop registers for kernel-level WiFi events — the OS notifies the app the instant something changes. Zero polling means zero battery impact and zero missed events between polls. PRIVACY: SignalDrop makes zero network requests. No analytics. No telemetry. No accounts. No data leaves your Mac. WiFi events are stored in a local SQLite database that you control. Your location (required by macOS for WiFi network names) is never recorded or transmitted. WHAT'S COMING: • v1.1: Nearby network scanner + real-time signal/noise graphs • v1.5: Customizable menu bar display + AP vendor identification + roaming alerts • v2.0: Channel-conflict detection + advanced analyzer mode All 1.x updates included free for existing buyers.

v1.1 is the biggest upgrade since launch. SignalDrop now does much more than catch disconnects — it explains them. NETWORK INSIGHTS WINDOW A new three-tab window (⌘N) gives you the picture every WiFi tool should: • Nearby networks — every AP your Mac can see, with signal bars, vendor identification (Apple, Cisco, TP-Link, Netgear, Ubiquiti, Google, Eero, Sagemcom, Arris, AVM, MikroTik and 19,000 others pulled from the IEEE registry), band, channel, and security. Sort, filter by 2.4 / 5 / 6 GHz, and spot your connected network at a glance. • Signal graph — a live RSSI / Noise / TX-rate chart with hover inspection (cursor over any point shows the exact dBm, noise floor, SNR, and link rate at that moment), 1m / 5m / 15m / 1h time-range presets, and a pause button for when you want to study a specific moment without it scrolling away. • Connection history — a 24h / 7d / 30d reliability report with an A–F grade, uptime %, outage count, total downtime, and a per-network rollup that tells you which network is actually responsible for your bad day. Click any outage to drill in — see the 60 seconds of signal/internet events leading up to the disconnect. PDF "ISP-READY RECEIPT" EXPORT Generate a branded one-page PDF of your reliability report — grade, timeline strip, per-network breakdown, every outage with timestamps — ready to send to your ISP, employer, or coworking-space landlord. PHANTOM-DROP SUPPRESSION Most disconnect notifiers fire on every 1-second flicker when your Mac roams between access points. SignalDrop ignores drops shorter than a threshold you set (5 seconds by default — tunable in Settings) across notifications, your reliability grade, and the per-network rollup. The raw events still land in the database so the ISP receipt can include them if you want, but the parts of the app you actually look at agree on what counts as a "real" outage. NOTIFICATION SETTINGS WINDOW A proper macOS preferences window (⌘,) with per-event toggles (Disconnect / Reconnect / Weak signal / Internet unreachable / etc.), minute-precision quiet hours that silence everything during the window — disconnects and internet-lost included — a sound toggle, and a "Send test notification" button so you can preview exactly what alerts will look like. PRESENTATION POLISH • Menu bar icon now reflects state — full Wi-Fi glyph when connected, variable strength based on signal, exclamation when internet is unreachable, slash when WiFi is off. • Hover annotations on the Signal Graph (timestamp, RSSI, Noise, SNR, TX rate — Apple Stocks-grade). • "Connected" pill in the scanner so you can spot your network in a busy 20+ row scan. • Grade pill in History has a hover tooltip explaining the math and what you'd need to clear for the next grade up. • Accessibility labels on every custom control — VoiceOver speaks signal strength, tab names, toggle state. For everyone running cafes, working from home, on a flaky hotel WiFi, or just tired of guessing whether the slowness is the app or the network — SignalDrop now has the answer.
