Faxbu: Flash Log

Faxbu is built for film photographers who collect vintage hot shoe flash units and need to know — before the shoot — which ones are ready and which ones need work. Photograph any flash unit with your phone. AI scans for capacitor aging indicators, hot shoe contact oxidation, and bounce head wear. Get a Health Rating Card for that unit in seconds. Every assessment is saved to that flash's own maintenance history. Scroll back through any unit's condition curve to catch deterioration early. Go into a shoot knowing exactly which flashes to bag and which to bench. Collectors who have five, ten, or twenty vintage flashes can finally manage their kit the way a working pro manages gear — with actual records, not guesswork.
