SensorDeck - Pro ThingSpeak Dashboard & Alerts Unlock the full potential of your ThingSpeak IoT projects with SensorDeck! Whether you're a hobbyist, a student or an IoT professional, SensorDeck lets you monitor, analyze and act on your sensor data from iPhone, iPad and Apple Watch ā anywhere, anytime. Tired of clunky web pages on your phone? SensorDeck is a native app built for Apple devices: clean, fast and full-featured. No account needed ā it reads your ThingSpeak channels directly. New in v1.5.0: SensorDeck now keeps an eye on your sensors beyond the app. BEYOND THE APP ⢠Home Screen and Lock Screen widgets: Put any sensor on your Home or Lock Screen with its latest value and recent trend. Widgets refresh on their own, even when the app is closed. ⢠Apple Watch app: Patrol every sensor from your wrist. Sensors in alert or offline are listed first; tap one to see its value, trend and high/low. A haptic at the end tells you "all clear" or "something is wrong". ⢠Watch complications: Put a sensor right on your watch face. ⢠Shortcuts automations and Siri: Check your sensors on a schedule and get notified only when something is wrong, or turn on an air purifier or fan when a value runs high. You can also ask Siri: "Get a sensor reading from SensorDeck". SMART ALERTS ⢠Six conditions: greater than, less than, outside a range, inside a range, rapid change, and sensor offline (stopped reporting). ⢠Advanced options: quiet hours, a minimum repeat interval, back-to-normal notices, and custom messages with the channel, value and time. ⢠Many channels: local push notifications, a Telegram bot, and universal Webhooks (Discord, Slack, IFTTT or your own API). ⢠Monitors every channel at once, not only the one on screen. ⢠Alerts are checked while the app is open with auto-refresh on. When the app is closed, pair it with a Shortcuts automation for scheduled checks. PRO-GRADE CHARTS ⢠Built on Apple Charts, with line, area and bar charts and touch to inspect any data point. ⢠Time ranges from 10 minutes to 1 week. Time labels adapt automatically, and every field in a channel shares the same time axis for easy comparison. ⢠Long ranges load in parts with progress, and the chart fills in as data arrives. ⢠Live statistics: maximum, minimum and average for any time range. ⢠When a range has no data, SensorDeck explains why and shows when the channel last reported. DATA MANAGEMENT ⢠Choose how long data is kept on your device (6 hours to 7 days) and view recent data even offline. ⢠CSV export: export one channel or all of them, using a preset or custom range of up to one year, downloaded from ThingSpeak on demand. ⢠iCloud sync: alert rules and chart styles sync automatically between your iPhone and iPad. ⢠QR codes: scan or share channels to add them quickly. DESIGN AND LANGUAGES ⢠An animated background and a carefully tuned dark interface. ⢠The app, widgets, Apple Watch and Siri fully support English, Traditional Chinese and Japanese. FREE AND PREMIUM The free version includes 1 channel, basic alerts (greater than / less than) and the small Home Screen widget. Premium ā a one-time purchase, not a subscription ā removes ads and unlocks unlimited channels, advanced alerts, Telegram and Webhook notifications, medium and Lock Screen widgets, the full Apple Watch list and complications, Shortcuts and Siri, and CSV export and data management. Stop guessing, start knowing. Download SensorDeck and take full control of your IoT data!

Verdict
The clearest difference is in-app purchases: Voltsec at none against SensorDeck's 1. Voltsec also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 5 weeks). On price and device support there is nothing between them.
