SipNoteBoba, Latte & Sleep Coach
Formerly known as SipLog.
About
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

How SipNote compares
Honest, dimension-by-dimension comparisons — including where the other tool wins.
Caffeine tracking app
SipNote vs HiCoffee
HiCoffee is one of the most-loved caffeine trackers on iOS — and rightly so. It pioneered the genre, has thousands of 5-star reviews, and is genuinely well-built. SipNote is the app I built after a year of using HiCoffee. Here's an honest, dimension-by-dimension look at where they overlap and where they diverge, so you can pick the right one for you.
Caffeine tracking app
SipNote vs RECaf
RECaf is a well-loved indie caffeine tracker for iPhone with a developer who responds personally to feedback on Reddit. SipNote is a newer entrant with a different bet on what makes drink logging fast. Here's an honest dimension-by-dimension look.
Caffeine tracking app

Caffeine tracking app
SipNote vs UP Coffee
UP Coffee (from the original Jawbone team) was the app that popularized the idea of treating caffeine like a quantified metric. It's still installed on millions of phones. SipNote is a 2026 take on the same idea, with modern Apple hardware in mind. Here's an honest dimension-by-dimension look.
