Question 3

Which cube types are supported?

Accepted Answer

Zkt Timer supports all official WCA categories: 2x2, 3x3, 4x4, 5x5, 6x6, 7x7; Pyraminx, Megaminx, Skewb, Square-1, Clock; 3x3 One-Handed, 3x3 Blindfolded and more. Official WCA scramble algorithms are used for each category.

Question 4

Can I use it offline?

Accepted Answer

Yes! Zkt Timer works offline thanks to PWA technology. After installing the app via your browser's 'Add to Home Screen' option, you can use the timer without internet. Your data automatically syncs when you reconnect.

Question 5

Is it an official WCA timer?

Accepted Answer

Zkt Timer uses official WCA scramble algorithms and is built for training purposes. Physical Stackmat Timers are required for official WCA competitions. Zkt Timer is ideal for practice, training, and statistics tracking.

Question 6

Which devices are supported?

Accepted Answer

Zkt Timer works on all modern browsers. Windows, macOS, Linux, Android and iOS are supported. It can be installed as a PWA on your phone. It's also compatible with Smart Cubes (GAN, MoYu) and Stackmat Timer.

Question 7

Is my data safe?

Accepted Answer

Yes, all solve records and account information are stored securely. Your data is kept both on the server and in your browser's local database. You can delete your account and all data at any time.

Question 8

How can I join online races?

Accepted Answer

Create an account, then join open race rooms or create private rooms with friends from the 'Rooms' section. Real-time races are held and you can climb the rankings.

Question 9

How can I track WCA competitions?

Accepted Answer

Browse all WCA Rubik's cube competitions worldwide from the 'Competitions' section. Each competition's detail page shows schedule, competitor list, events and live results. Connect your WCA account to see your personal schedule for competitions you're registered for.

Question 10

How do I connect a smart cube?

Accepted Answer

Zkt Timer supports GAN, Giiker, and Particula smart cubes via Bluetooth. On mobile, enable Bluetooth and use the Capacitor BLE plugin; on web browsers, use Chrome or Edge which support Web Bluetooth. Open the Smart Cube menu from the timer, press Scan, and pair with your device. Once connected, the timer auto-starts and stops based on the cube state.

Question 11

Does Zkt Timer support Stackmat Timer?

Accepted Answer

Yes. Connect your Stackmat Timer via the audio input (3.5mm jack). In the timer settings, select StackMat as the input type, then choose the correct audio input device. The timer will detect your Stackmat signals automatically.

Question 12

What is the algorithm trainer?

Accepted Answer

The algorithm trainer helps you drill OLL, PLL, F2L, ZBLL, and other cube algorithms with spaced repetition. It shows a 3D cube or 2D pattern for each algorithm, tracks your solve time per algorithm, and queues the ones you need most practice on. It supports smart cubes for pattern matching.

Question 13

What are OLL and PLL?

Accepted Answer

OLL (Orientation of the Last Layer) and PLL (Permutation of the Last Layer) are the final two steps of the CFOP speedsolving method. OLL has 57 algorithms that orient the last layer; PLL has 21 algorithms that permute the pieces. Mastering these is essential for sub-20 solves.

Question 14

What does Pro membership give me?

Accepted Answer

Zkt Timer Pro unlocks advanced statistics, unlimited sessions, PDF export of your algorithms and stats, access to all algorithm trainers, premium themes, and priority support. It's a one-time or recurring purchase depending on the plan.

Question 15

Can I import data from csTimer or Twisty Timer?

Accepted Answer

Yes. Zkt Timer supports data import from csTimer, Twisty Timer, and its own previous export formats. Go to Settings > Data > Import, select the source format, and upload your export file. All solves, sessions, and metadata are preserved.

Question 16

How do I back up my data?

Accepted Answer

Go to Settings > Data > Export. Zkt Timer generates a JSON file containing all your solves, sessions, and settings. Store this file safely — you can re-import it on any device. Signed-in users also get automatic cloud sync.

Question 17

Which scramble algorithm does Zkt Timer use?

Accepted Answer

Zkt Timer uses the same scramble engine as cstimer, the de facto standard in speedcubing. This includes WCA-compliant random-state scramblers for 2x2, 3x3, 4x4, Pyraminx, Megaminx, Skewb, Square-1, Clock, and more. All scrambles meet WCA regulations.

Question 18

What is Battle mode?

Accepted Answer

Battle mode is a 1v1 competitive mode on a shared mobile screen. Two cubers race side-by-side with independent start timing, penalty tracking (+2, DNF), round-by-round scoring, and a review modal to examine each round. Perfect for quick duels with a friend.

Question 19

How do I get on the leaderboards?

Accepted Answer

Global leaderboards show top single solves and top averages. To appear, you need a Zkt Timer account, verified solves (from the timer, not manual entry), and the solve must not be flagged. Top times are auto-published; you can also manage which solves are public.

Question 20

Can I delete my account?

Accepted Answer

Yes, completely. Go to Settings > Account > Danger Zone > Delete Account. This permanently removes all your solves, sessions, profile data, and WCA link. The action is irreversible. Export your data first if you want to keep a backup.

Question 21

Is Zkt Timer free?

Accepted Answer

The core Zkt Timer is completely free: timer, scrambles, basic stats, online rooms, leaderboards, and the algorithm trainer. Pro membership ($optional) unlocks advanced features. There are no ads.

Question 22

Is there an iOS or Android app?

Accepted Answer

Yes. Zkt Timer is available natively on the iOS App Store and Google Play Store. The apps include smart cube Bluetooth support, offline mode, push notifications, and native performance. You can also install the web app as a PWA.

Question 23

What is inspection mode?

Accepted Answer

Inspection mode is the 15-second countdown before each solve, matching WCA regulations. During inspection, you examine the scramble without touching the cube. An audible 8-second and 12-second warning plays, and starting after 15 seconds incurs a +2 penalty (17+ seconds is DNF).

Question 24

Are stats tracked separately for different cube types?

Accepted Answer

Yes. Zkt Timer buckets stats by (cube type, scramble subset). Your 3x3 averages, 2x2 personal bests, and Pyraminx times are all tracked independently. The Stats page lets you filter by cube type and time range.

Question 25

How does Zkt Timer work without internet?

Accepted Answer

As a PWA, Zkt Timer caches all app files after the first visit. You can time solves, generate scrambles, and view cached stats fully offline. When you reconnect, pending solves are automatically synced to the server via Background Sync API.
