About

Stackful

Read full description

Stackful helps you keep track of the supplements you have at home and see which ones will run out next. Add a supplement once: how much you have and how much you normally use each day. Stackful estimates how long your stock may last, when it is expected to run out and when it may be sensible to order more. There is no daily logging – the estimate follows your normal daily use. KNOW WHAT YOU HAVE • See your whole Cabinet at a glance, with remaining amounts and days left • Use the unit that matches the product: tablets, capsules, softgels, gummies, grams, scoops, servings, millilitres or your own unit • Pause a supplement you are not using right now, or archive it and keep its history PLAN YOUR NEXT RESTOCK • See an estimated empty date and a suggested order date for each supplement • Next order groups the supplements that are running low, so you can plan one sensible order • Optional stock heads-up: one notification per supplement on its suggested order date – never daily reminders KEEP ESTIMATES CURRENT • Add stock when a new container arrives, even before the current one is empty • Correct the remaining amount or change the daily amount whenever something changes GOING AWAY? • Choose your travel dates to see whether your supplements are estimated to last, and how much of each to pack PRIVATE BY DESIGN • Your data is only stored on this iPhone • No Stackful account, no advertising, no analytics and no Stackful server • Available in English, Norsk bokmål, Español, Deutsch, Français and Português (Brasil) STACKFUL FREE AND STACKFUL PLUS Stackful Free includes up to three supplements in your Cabinet. Paused supplements count; archived supplements don’t. Stackful Plus is an optional one-time purchase that removes that limit. Everything else in Stackful is the same. Payment is charged to your Apple Account when you confirm the purchase. Stackful Plus is a one-time purchase, not a subscription. You can restore it on any iPhone signed in to the same Apple Account. Stackful is an inventory-planning tool. It does not provide medical advice or recommend supplements.
