Hi everyone,
I'm Ibrahim (ibrhyyme), a cuber from Turkey. For the past year and a half I've been building Zkt Timer, a timer that started as a simple tool for my own practice and slowly turned into a full app. It runs on the web and as native iOS and Android apps, and your solves sync across all of them.
There are already great timers out there and I learned a lot from them. Our scramblers are built on csTimer's, and the Credits page in the app lists every project that helped. So instead of listing the usual timer features, here is what I think you won't easily find elsewhere:
MOBILE:
DESTOP:
Magnet Timer
Lay your phone flat, put your magnetic cube next to it, lift the cube to start and put it down to stop. You never touch the screen. It uses the phone's magnetometer, with a short calibration for each cube. It works in the iOS and Android apps only, it is still in beta, and not every phone's sensor is fast enough.
Online Battle with smart cubes
1v1 against whoever is searching at the same moment: same scramble, first to win three rounds. Time comes from the cube's own clock, so internet lag never decides a round, and the server checks every solve against its move log. Glicko-2 ratings and a public leaderboard. Works with GAN, QiYi and WeiLong V10 AI cubes.
WCA competition tracking with push notifications
Browse WCA competitions with groups, assignments, schedule, live results and each competitor's duties and PBs. If you are registered, the app notifies you when groups are published, when the schedule changes and when official results are in. There is also a feed of recently broken records and a "record radar" that shows which records could fall at an upcoming competition.
Smart cubes
GAN, MoYu, QiYi, Giiker, GoCube and more, in the browser (Chrome/Edge) and natively on iOS and Android. Scramble moves are ticked off as you turn, with the fix shown if you make a wrong move. After each solve you get a Cross / F2L / OLL / PLL breakdown with TPS and a replay.
Trainer
OLL, PLL, F2L, ZBLL, OLLCP and more, with a smart cube mode that checks your execution, a PLL recognition trainer and a cross/xcross trainer. You can build your own algorithm sets, send them to a friend with a link or publish them for the community.
Social
Direct messages where you can attach a solve, real-time rooms with chat and spectators, and an offline 1v1 mode for two people on one device.
Everything else
Keyboard, touch, StackMat, GAN Timer and QiYi Timer input, full WCA inspection, sessions and detailed stats, offline mode with sync, import from csTimer and Twisty Timer, and five languages (English, Turkish, Spanish, Russian, Chinese).
Some features, like Magnet Timer and the smart cube solve analysis, need a Pro subscription.

I build this mostly on my own, so feedback means a lot: bugs, smart cubes that won't connect, features you would like to see. Thanks for reading!
