Autophagy

Your daily longevity stack.

Autophagy is a daily tracker for the five practices most strongly linked to cellular renewal: fasting, exercise, cold immersion, sauna, and Reset Breathing.

One daily score out of 100. Default target is 42 (a deliberate nod to The Hitchhiker's Guide to the Galaxy, changeable in Settings). The scoring rewards spreading practices across modalities rather than maxing out a single one. The streak matters more than the score.

It is built for athletes and serious practitioners who want a clean view of how often they actually do the things that matter, not yet another data dashboard.

Privacy first. No account, no sign-in, no cloud sync. Everything you log lives on your device, stored locally via Apple's SwiftData framework. No analytics SDKs, no advertising networks, no tracking. Delete the app and the data is gone.

What it tracks
  • Fasting: Time-restricted eating, scored at 14, 16 and 18-hour windows, capped at 18 so the system never rewards extreme fasting.
  • Exercise: Running, cycling, weights, gym, yoga, walking. Calibrated per type so a 45-minute hard session and a 90-minute walk both count.
  • Cold: Cold immersion, plunge, ice bath or open water. Scoring rewards the two-minute mark and caps at five minutes.
  • Sauna: Calibrated to the Finnish dose-response data. Twenty-five minutes is the cap.
  • Reset Breathing: Three rounds of cyclical breathing with breath holds. The standard practitioner dose.

The original, 2009

iHi

Let your iPhone do the talking.

iHi turns the iPhone into a large, eye-catching speech bubble. Get someone's attention across a noisy room, communicate with a person wearing headphones, or just tell another driver exactly what you think of their driving (not while you are driving).

Tap a preset to display a message ("Hi", "Drink?", "U R Hot"). Drag the bubble across the screen with a finger. Upgrade to add your own messages with a custom keyboard that includes symbols and smileys.

It launched on 6 October 2009, in the early years of the App Store. Since then it has been updated for new iPhones, iPad, Bluetooth-based remote display, AirDrop sending, and seven preloaded languages. It still works on the latest iOS.

"Not clear what it's for at first, then after five minutes you can't live without it."

Seventeen years apart, the same approach

iHi and Autophagy could not be more different in purpose. The thread between them is how they are made.

Focused

Each app does one thing properly. No feature bloat, no second-screen settings menus. The Today tab in Autophagy is one screen. iHi is one tap to display.

Built by users

Autophagy was built by a practitioner who actually fasts, lifts, plunges and sweats. iHi was built because the founder kept losing people in noisy bars. We ship the apps we want to use.

Made in England

Designed and built in Bath. Alamex Ltd has been a UK-registered iOS developer since the App Store opened in 2008.
