Putby: Canning & Pantry Log

Putby is a home-canning and food-preservation companion — a safety-first jar log, a living pantry inventory, and an altitude-aware safe-processing reference. Not another thin recipe app. Log every batch you can, ferment, pickle, dehydrate, or freeze in seconds. Putby tracks what's on your shelf, when it's best-by, prints the labels, and keeps you on the right side of the safe-processing rules.

Put it by — safely. Know what's on your shelf, when it was canned, and that you canned it right.

WHY CANNERS CHOOSE PUTBY
• The safe-processing reference is FREE — water-bath vs pressure canning, altitude auto-adjust, headspace and acidity, plus a botulism check that flags low-acid foods that must be pressure-canned. Grounded in tested USDA/Ball guidance. We will never paywall safety.
• Honest billing — cancel anytime in Google Play. No surprise fees, no "watch a video to see the recipe," no card needed to explore.
• Works offline, opens instantly — local-first, no account, nothing to crash. Works in the cellar, the garden, or a dead zone.
• A living pantry, not just recipes — know exactly what's on your shelf and what to eat first.

FREE FOREVER
