Wet filament ruins prints. iDryer keeps it dry automatically while you focus on other things. The first app for controlling the iDryer filament dryer. Connect your device and get full control, monitoring, and process visualization. iDryer works with the whole ecosystem of the project: dryers, iHeater, Storage Link, other devices, and your own ones that you can come up with yourself. DEMO MODE No device yet? Get to know the app on demo units—they behave like the real thing: live telemetry, drying runs, heating, falling humidity, and weight loss. REAL-TIME TEMPERATURE AND HUMIDITY Track the drying process without having to stay nearby. All key readings are on the home screen. WEIGHT CONTROL See filament weight on the spool and how much moisture has been removed. No guesswork, just data. DRYING PROFILES Ready-made modes for drying most materials. Expand your library, share, browse community profiles, and get better results. Before a run you can see the profile stages—temperatures and durations. SPOOL STORAGE Racks, shelves, and slots: every spool has its own place. Move and swap spools, load them into the dryer, keep a usage history and storage conditions. RFID TAGS Read a tag with your phone in the OpenSpool, OpenPrintTag, and TigerTag formats, and bind it to a spool in one action. An RFID section has been added to Tools—read, erase, and write a test tag. RFID/NFC features are available on devices with NFC support. PUSH NOTIFICATIONS Devices report every change. EASY CONNECTION The app passes your Wi-Fi network details to the device and binds it to your account. LAN AND CLOUD Control your device on the local network or remotely through the cloud. FILAMENT CATALOG Brands, material types, and key properties are always within reach. FORUM Discussions, answers, and owner experience inside the app. Topics are translated into the app language automatically. SESSION HISTORY Analyze results, share, compare sessions, and improve print quality. Built for people who take 3D printing seriously.

Verdict
The clearest difference is update cadence: iDryer at every 3 months against FilamentFlow's every 8 months. iDryer also leads on iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
