DozTimer vs Ambient Time
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
DozTimer
Read full descriptionHide full description
The Dozenal Suite is a set of five apps for dozenalists! They run on Apple’s mobiles (with iOS 18 or later). On any timing device, the day is divided by successive powers of 12, providing metric time reckoning based on twelves rather than tens. The leftmost digit changes every 2 hours (1/12 day), the next digit every 10 minutes, the next every 50 seconds. If displayed, the fourth digit changes every 4 1/6 seconds and the fifth digit every 25/72 second. In the dozenal number base, because the number 10 is one dozen, numerals ten and eleven must be single digits. They are represented by the symbols invented long ago by Isaac Pitman: rotated 2 for ten, and rotated 3 for eleven. Those are used by the two major dozenal societies, the Dozenal Society of America and the Dozenal Society of Great Britain. In the plain text below, ten is designated by the letter A, and eleven by the letter B. The timer app may be set for any time between dozenal 000.01 and BBB.BB. It counts down by the last digit, the Primel metrology's twinkling.

Put time where it belongs: on your Home Screen, Lock Screen, Apple Watch, Apple TV, Mac, or the biggest display in the room. Ambient Time is a native collection of clocks and useful glances. Explore 47 ways to read the moment on iPhone and iPad—from precise word grids and binary displays to astronomy, weather, mathematics, and generative art. ONE HOME FOR EVERY SCREEN The destination-first control center organizes Widgets, Apple Watch, TV & Displays, Clocks, and Instruments. Browse what fits each surface, preview it live, and choose starting defaults without pretending to control system-owned placement. CLOCKS WITH A POINT OF VIEW • Word Clock spells out time in nine languages plus IPA. • Cosmic brings the sun, moon, horizon, and zodiac into one quiet astrolabe. • Tide follows local predictions and highlights the next high or low. • ASCII World Clock wraps global hours around a text-art globe. • Moon Track follows the live lunar phase. • About Time turns optimistic phrases into the hands of a clock. • Inkwell Ledger lets the day unfold as a handwritten journal. • Mandaza draws a generative clock that never repeats exactly. WIDGETS MADE FOR THEIR SPACE Ambient Time groups Home Screen clocks and information widgets by size, so every layout stays clear and useful. Because the Lock Screen already shows Apple's clock, Ambient Time adds context instead: moon phase, golden hour, rain, tides, and poetry in Inline, Circular, and Rectangular forms. A CALMER GLANCE ON APPLE WATCH Choose from six legible clocks in the Watch app. Add nine Smart Stack widgets and complications for tides, rain, forecasts, golden hour, moon phase, world moments, words, compliments, and poetry. MADE FOR THE ROOM—AND THE MAC Apple TV offers a remote-first gallery of Ambient clocks and fixed dashboards. Mac brings the same destination control center to the desktop, including fullscreen Ambient Mode, dashboards, and Desktop or Notification Center widgets. Five global color themes are available where a clock supports them. Weather, sun, moon, and tide features use coarse location only with permission. There are no accounts, ads, subscriptions, or purchases, and location is never used for tracking. Built natively in SwiftUI with Reduce Motion support. Made by Luke Steuber.

Verdict
The clearest difference is device support: Ambient Time at 5 against DozTimer's 2. On price, ads, in-app purchases and iOS requirement there is nothing between them.
