Works flawlessly as mentioned, exactly doing the workflow I planned to add to my 3d printing hobby. I was almost given up until I found SpoolFlux, similar apps or software appear on Android or Chromebook world, but not iOS until now and this app really save the iOS community. Look forward to getting more features and expanded material database with hex color data.Well done Reinar, appreciate the work.
Developer Response
Thanks a lot for the awesome review — really appreciate it! Great to hear that SpoolFlux fits your workflow. More features and a bigger material database (including hex colors) are definitely coming. 🙂
New: TigerTag support—read and describe TigerTag RFID tags. Stability and compatibility improvements.
