InkBatch

InkBatch is an organisational and arithmetic tool for small screen-printing workshops. Record your own recipes, scale them to the batch you actually need, and mix step by step watching a single number instead of doing arithmetic in your head at the scale. RECIPES AND SCALING • Your own recipes, with your own names and codes • Scaling to any target mass, with a total exact to the milligram • Scale resolution: the app tells you which component is too small to weigh, and how large a batch has to be before that stops being a problem • Your own notes on a component, such as "add slowly" • A target colour on a recipe as your own reference, with a HEX code • Reading an approximate colour out of a picture you choose MIXING • Guided mixing, one component at a time, with a running total for the scale • Pause and resume — the phone can be put down halfway through a batch • Overshoot Recovery: when you pour too much, you enter the actual mass and the app works out the smallest larger batch that keeps your proportions. Nothing is poured back, and nothing undoes the work you have already physically done STOCK AND HISTORY • Ingredient stock with a movement history and reversible corrections • Batch history, recorded as it stood at the moment of mixing • Batch cost from the prices recorded when the mixing started — changing a price later does not rewrite history • Leftovers YOUR DATA • Backup and restore from a file, with the contents checked before anything is restored • A safety copy written automatically immediately before every restore • Delete all data behind one deliberate confirmation • 25 languages, light and dark themes WHAT IT DOES NOT DO InkBatch calculates on the data you enter, and on nothing else. It does not assess chemical safety, product compatibility, toxicity, flammability, storage or disposal. It does not guarantee colour or production outcome. It contains no third-party colour system. It does not replace manufacturer instructions or safety data sheets. Check every result before production use. PRIVACY No account. No server. No synchronisation. No adverts. No analytics. No crash reporting. InkBatch holds no INTERNET permission and never sends your recipes anywhere itself. A backup file leaves the app only when you deliberately choose a destination in the system save dialog or the system share sheet. A backup is created only when you ask for one, or immediately before a restore.
