CupCoach
A personal caffeine coach that logs every cup from your usual order and tells you when to stop drinking for tonight's sleep.
health-conscious adults who drink three to five cups of coffee a day and wonder what it is doing to their sleep and energy
- One-tap logging via receipt OCR, loyalty-card scan or a quick-pick from your usual order

- Plain-language summaries of the latest caffeine research refreshed every month
- Smart swap suggestions like 'try a half-caff after 1pm — your sleep score trends six points higher'
The American Heart Association has just clarified that up to five cups a day is fine for most adults, reopening a question millions of coffee drinkers quietly worry about.
Coffee is ubiquitous, but caffeine-tracking is a niche — appshunter lists 233+ caffeine tracker apps, mostly tiny. The AHA '5 cups safe' story is real and covered (heart.org, ABC News) but is a single news cycle, not a sustained behavioral shift toward active logging.Coffee and heart health: How many cups of caffeinated coffee are safe to drink each day ↗233+ Best Caffeine Tracker Apps for iPhone (2026) | Free & Paid ↗
The market is saturated. A dedicated roundup names 9 direct competitors (HiCoffee, Caffi, Caffeine Clock, RECaf, etc.), and the #1 pick 'Caffeine Tracker: Sleep Better' already offers exactly the CupCoach pitch: a personalized cutoff time that models your half-life and bedtime. CupCoach is not a category-defining idea, it is a copycat.Best 9 Caffeine Intake Trackers in 2026: Sip Smarter, Not Harder ↗Caffeine Tracker: Sleep Better - App Store ↗
Caffeine tracker apps are overwhelmingly freemium with the core cutoff feature free (Caffeine Tracker, HiCoffee, Caffi) and only 'deeper insights' behind a paywall. Users are notoriously reluctant to subscribe to small habit trackers; no evidence of strong WTP, and the niche is too narrow for employer/insurance channels.Best 9 Caffeine Intake Trackers in 2026: Sip Smarter, Not Harder ↗Caffeine Tracker: Sleep Better - App Store ↗
Coffee consumption itself is durable, so the underlying habit persists. However, the 'why now' catalyst is a one-time AHA news cycle, not a secular trend, and the caffeine-tracking category shows a long tail of small apps rather than a growing mainstream behavior.Coffee and heart health: How many cups of caffeinated coffee are safe to drink each day ↗Best 7 Caffeine Tracker Apps in 2026: Track Your Intake Smartly ↗
Trivially buildable — half-life decay math is well-known, drink databases are widely available, and Apple HealthKit/Health Connect integration is off-the-shelf. The 9 existing competitors prove the technical bar is low.Best 9 Caffeine Intake Trackers in 2026: Sip Smarter, Not Harder ↗
