SipNote: Caffeine Tracker
Boba, Latte & Sleep Coach
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Know exactly when caffeine clears so you sleep tonight. Scan any cup, log boba in one tap, see your half-life curve live on Apple Watch.
SipNote is a beautifully designed caffeine and beverage tracker for coffee, tea, milk tea, and energy drink lovers. Built local-first for iPhone, iPad, and Apple Watch.
Snap a photo of any drink — on-device OCR auto-fills brand, drink, and size. No typing. No cloud upload. Your data stays on your device.
— WHAT MAKES SIPNOTE DIFFERENT —
• PHOTO LOG WITH ON-DEVICE OCR
Point your camera at a cup, receipt, or label. SipNote recognizes hundreds of brands — Starbucks, Luckin, HEYTEA, Naixue, Manner, KFC, plus generic coffee shops and bottled drinks — and fills in caffeine content automatically. Vision framework runs on your device. Nothing uploaded.
• REAL-TIME CAFFEINE METABOLISM
A live curve shows the caffeine currently in your bloodstream based on half-life math. The 'clear by HH:mm' estimate tells you when your level will drop below the sleep-safe threshold — so you know whether to drink another coffee.
• APPLE WATCH NATIVE
Glance at your current caffeine level on the watch face. Modular, Modular Compact, Modular Large, Corner, Inline, Circular, Graphic Bezel, Graphic Corner, and Graphic Circular complications all supported. Series 9+ Double Tap gesture logs your most-frequent drink.
• BOBA, MILK TEA, AND ASIAN BEVERAGES
Unlike Western trackers that treat boba as 'generic tea,' SipNote ships with 30+ Asian beverages and brands native — naixue boba, HEYTEA cheese milk tea, KFC iced coffee, popular bottled teas, and more.
• NO SUBSCRIPTION. NO ACCOUNT.
Everything you need to log and view is included at no additional purchase. Optional one-time Pro in-app purchase adds bedtime alerts, full unlimited history, drink map, CSV export, and Apple Watch quick-add tiles.
• PRIVACY BY DEFAULT
100% on-device storage. No accounts, no telemetry, no cloud round-trips. iCloud sync is optional and end-to-end-encrypted by Apple. We literally cannot see your data.
— WHO IS SIPNOTE FOR? —
• People who want to know whether their afternoon coffee will affect sleep
• Boba and milk tea drinkers who track Western caffeine apps fail
• Pregnant or trying-to-conceive folks watching daily caffeine intake
• Anyone reducing caffeine without going cold turkey
• Anyone who has tried HiCoffee, RECaf, Caffi, or UpCoffee and wanted something faster to log into
— PRICING —
Daily logging and basic features are included at no additional purchase. One-time Pro in-app purchase — never a subscription. Pay once, own forever.
