Chronographer vs Tickscope
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Chronographer
This app helps you meticulously track the accuracy of your mechanical watches. It records time differences, calculates detailed performance metrics, and visualizes trends with charts and histograms. You can also manage your watch collection, log daily wear, and analyze positional variations.

Chronographer is for people who enjoy mechanical watches. It does two things: 1. Tracks your watches’ long-term accuracy 2. Records wrist time Chronographer can work with your whole watch collection. Create a “card” for each watch, giving it a name and, optionally, a longer description. Select a picture from your Photos library and add additional notes, such as the watch’s specifications, purchase details, and service history. All information is stored in iCloud and automatically synchronized between your devices. To track a watch’s accuracy, periodically collect data points comparing its indicated time to the current correct time. Chronographer tracks offsets (the difference from the correct time) and daily rate (how many seconds it gains or loses per day). It uses this information to create graphs and histograms that help you visualize your watch’s performance over time. Chronographer also calculates the following metrics: * Average offset * Max. positive offset * Max. negative offset * Last offset * Net gain/loss * Best-fit rate * Average rate * Fastest rate * Slowest rate * Last rate * Rate variance * Best-fit rate drift You can log the watch (or watches) that you wear each day. Chronographer’s wrist time tracking feature lets you see which watches you wear the most and how long it’s been since you’ve worn each one. You can use Chronographer to identify positional variation. When you record a data point, include the position (dial up, crown up, etc.) that the watch was stored in. Then, you can restrict the charts and metrics to specific positions and compare the results. Chronographer includes a large digital clock to help when you set your watches. For more information, including a detailed user’s guide, see https://www.rmfrance.net/chronographer

Hear what your watch is really doing. Tickscope turns your iPhone or iPad into a timegrapher: set the watch by the microphone and read its rate, beat error and amplitude. No extra hardware. MEASURE • Rate (s/d), beat error (ms) and amplitude (°) • Beat rate detected automatically: 18,000, 19,800, 21,600, 25,200, 28,800 and 36,000 bph • Every result in plain words, like "gains about a minute every 28 days", graded by how confident the reading is • Coaching tells you what to change when the room is noisy or the ticks are faint LOOK CLOSER • Anatomy of a tick: unlock, impulse and drop, averaged from your own watch's beat • Magnetism check with your device's compass YOUR COLLECTION • Photos, measurement history, heritage notes and a wear calendar for every watch • A chronograph clock face with Breguet hands, moon phase and split seconds TICKSCOPE PRO Buy it once, keep it. No subscription. • COSC-style five-position assessment (an at-home check, not a certificate) • Trends over weeks, position by position • Timing certificates as PDF • Power reserve test • Unlimited watches and measurements The free version includes 25 measurements and up to 3 watches. LIBRARY Articles, a 230-term glossary, 200+ calibers and 1,000+ watches to read between measurements. PRIVATE BY DESIGN Sound is analysed on your device and never leaves it.

Verdict
The clearest difference is review sentiment: Tickscope at 100% against Chronographer's 50%. Tickscope also leads on rating (4.6 vs 3.4) and update cadence (every 9 days vs every 2 months). Chronographer's advantage is in-app purchases (none vs 1). On price, ads, device support and iOS requirement there is nothing between them.
