About

Chrono

Chrono calls Dota 2 objectives before they happen, so you can keep your eyes on the map. Runes, stacks, pulls, Roshan, Tormentor, the day-night cycle, neutral item tiers and more โ€” all read off the real match clock and spoken out loud a few seconds before the window opens. Put the phone beside your keyboard and stop counting in your head. HOW IT WORKS Dota 2 already publishes the match clock. Chrono Link, a small free companion for Windows or macOS, reads it and sends it straight to your phone across your own network. Pair once and every match after that syncs on its own at the horn. No computer nearby? Manual mode runs every timer from a single tap at the horn. WHAT IT DOES โ€ข Spoken callouts a few seconds ahead, with a countdown you can feel through haptics โ€ข Every objective on one board, ordered the way you play โ€” or set your own priority โ€ข Harmonics: when several timers land on the same second, it says all of them โ€ข Live match clock straight from the game, accurate to the second โ€ข Manual mode that needs no computer at all โ€ข Portrait, dark, and readable from across a desk PRIVACY No account. No analytics. No servers of ours anywhere. The match clock goes from your PC to your phone across your own home network and never leaves it.

About

Rune Clock

Features
Read full description

Rune Clock is an objective timer for Dota 2. It sits next to your keyboard and shows, in one enormous number, how long until the next thing spawns. You can read it without picking the phone up. THE BIG NUMBER The next objective fills the screen, colour-coded to what it is. Ten seconds out it starts to pulse and the phone buzzes. When it lands the screen flashes NOW for three seconds, so you catch it even if you looked away at the wrong moment. Underneath sits a row of everything else on its way. THE CLOCK IS YOURS There is no Steam connection, no overlay and no account. You tell it what time it is: tap SYNC and type the in-game clock, nudge it ten seconds or a minute either way if you have drifted, or restart at 0:00 on the horn. The clock is anchored to real time rather than counting ticks, so it stays right while the phone is locked or face down on the desk. ROSHAN AND TORMENTOR Tap when Rosh dies and you get the window: earliest to latest, counting down, then UP. Tormentor works the same way. EVERY TIMING IS EDITABLE Power runes, bounty runes, water runes, wisdom shrines, lotuses, neutral item tiers, Tormentor, camp stacking and the day/night cycle. Switch off the ones you do not care about, and edit the first spawn and interval of any of them. Patches move these numbers around. When that happens you correct it yourself in Settings instead of waiting for an app update. PRIVATE BY DESIGN No accounts, no advertising and no third-party SDKs. The only thing the app sends is anonymous usage statistics (which screens were shown and subscription steps), with no identifier, to our own server. Nothing personal about you or your phone is collected. SUBSCRIPTION Rune Clock is a subscription app. Subscribing starts a 1 month free trial, after which it is $4.99 per month. Payment is charged to your Apple Account when the trial ends. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period; manage or cancel it in Settings > Apple Account > Subscriptions. Any unused part of the free trial is forfeited if you buy a subscription during it.
