About Caffy and https://alanaknows.com/

In their own words, as submitted to SaaSHub.

Caffy
https://alanaknows.com/

Caffy tracks how much caffeine is actually in your body right now, not just how much you drank. It models absorption and decay with the Bateman equation and calculates your personal half-life, because caffeine does not clear at the same speed for everyone. Pregnancy, smoking, oral contraceptives,...

Features and specs

What each product offers, as listed by its team.

Caffy 5 features
https://alanaknows.com/ 5 features
  • Simple Interface
    Caffy typically offers a clean, user-friendly interface that makes it easy for users to track their caffeine or coffee consumption without a steep learning curve.
  • Health Awareness
    The app helps users become more mindful of their caffeine intake, potentially leading to better sleep habits and overall health awareness.
  • Quick Logging
    Users can quickly log their coffee or caffeine consumption, making it convenient to maintain consistent tracking habits throughout the day.
  • Visual Tracking
    Many caffeine tracking apps like Caffy provide visual charts and graphs that help users understand their consumption patterns over time.
  • Free or Low-Cost Access
    Apps in this category often provide basic functionality for free, making it accessible to users who want to try caffeine tracking without financial commitment.
  • Domain still registered
    The domain alanaknows.com is still owned and registered, meaning the owner has the option to reactivate or rebuild the site in the future rather than losing the domain entirely.
  • Placeholder prevents dead link errors
    Instead of showing a generic browser error (like a DNS failure), the hosting provider displays a suspended page notice, which can be less confusing to visitors than a broken connection.
  • Potential for future content
    Since the domain is intact, if the account issue is resolved, the original website content could potentially be restored without needing to re-register the domain.
  • Clear indication of status
    The suspended page URL (cgi-sys/suspendedpage.cgi) clearly signals that this is a hosting-related suspension rather than the site being permanently deleted, which can help users or search engines understand the temporary nature of the outage.
  • No malicious content risk
    Because the site is suspended and not actively serving custom content, there is no current risk of the site hosting malware, spam, or other harmful material that active but neglected sites might accumulate.

Possible disadvantages

  • Website is completely inaccessible
    The main URL redirects to a suspended page, meaning visitors cannot access any actual content, information, or services that the site was intended to provide.
  • Unprofessional appearance
    A suspended page gives a poor impression to visitors, potential clients, or collaborators, suggesting neglect, financial issues, or abandonment of the site or associated business/brand.
  • Loss of SEO and traffic value
    Prolonged suspension can hurt search engine rankings and any previously built organic traffic, as search engines may de-index the site or lower its authority due to inaccessibility.
  • Unknown cause of suspension
    The suspension could be due to unpaid hosting bills, terms of service violations, or technical issues, and without more context, users or stakeholders cannot know the severity or how soon it might be resolved.
  • No information available
    Since the site is suspended, there is no way to evaluate the actual content, design, functionality, or purpose of the original website, making it impossible to assess its value or quality.

Questions & Answers

As answered by people managing Caffy and https://alanaknows.com/.

What makes your product unique?

Caffy's answer

Most caffeine trackers are calculators: you log a drink and they add up milligrams. Caffy models what your body is actually doing with it.

  • It uses the Bateman equation to model absorption and elimination together, so the curve rises for roughly the first 45 minutes and then decays, instead of dropping the moment you log a drink.
  • It calculates a personal half-life rather than assuming five hours for everyone. Pregnancy, smoking, oral contraceptive use, age and sex all shift that number, and between two people it can differ by a factor of six.
  • Everything else follows from that: your daily cutoff time, your peak focus window, and a nightly sleep score estimating how much caffeine will still be circulating at bedtime.

The model and its sources (FDA, EFSA, NIH, Sleep Foundation) are documented inside the app.

Why should a person choose your product over its competitors?

Caffy's answer

  • The number is yours, not an average. Competitors apply one half-life to everyone. Caffy asks about pregnancy, smoking, contraceptive use, age and sex, and recalculates from there.
  • It answers the question people actually have. Not "how much did I drink" but "can I still have this coffee and sleep tonight".
  • It lives in the OS. Home Screen and Lock Screen widgets, Live Activities, a Control Center control and Apple Health integration, so you see your level without opening the app.
  • It works offline. Every entry is written locally first and synced afterwards.
  • It is properly localized. English, Turkish, German, Spanish and Japanese, all hand written.

How would you describe the primary audience of your product?

Caffy's answer

Three groups, in order of size:

  • People whose sleep is worse than it should be. They suspect caffeine and want to see the connection instead of guessing. This is the core audience.
  • People with a medical reason to watch intake. Pregnancy, arrhythmia, anxiety, reflux, or a doctor's instruction to stay under a specific milligram limit.
  • People cutting down or quitting. They use the reduction programs to taper without withdrawal headaches.

Skewed toward iPhone users in English speaking markets, roughly 25 to 45, comfortable with health data but not necessarily technical.

What's the story behind your product?

Caffy's answer

I built it because I could not sleep and did not believe caffeine was the reason. My last coffee was in the early afternoon, which every article says is fine.

When I actually worked through the pharmacokinetics, the "stop at 2 PM" advice turned out to be an average dressed up as a rule. It assumes a five hour half-life and a midnight bedtime, and almost nobody matches both. My own cutoff was hours earlier than I had assumed.

No app would tell me my number, so I wrote one. It started as a single decay curve and grew into the sleep score, the cutoff time and the reduction programs as I kept running into the next question.

Which are the primary technologies used for building your product?

Caffy's answer

  • iOS app: Swift and SwiftUI, MVVM with the Observation framework, SwiftData for the offline first local cache
  • Charts: Swift Charts
  • System integration: WidgetKit for Home Screen, Lock Screen and Control Center, Live Activities, HealthKit, UserNotifications, BackgroundTasks
  • Backend: Supabase (PostgreSQL with row level security, anonymous auth, Edge Functions)
  • Subscriptions: RevenueCat
  • Analytics: PostHog
  • Localization: hand written translations for English, Turkish, German, Spanish and Japanese
