How can we help?

Open the Score tab and tap New match. Choose the format, add both teams and their players, then do the toss and pick bat or bowl.

Tap START MATCH and the scoring screen opens.

T20 (20 overs), ODI (50 overs), Test, or a custom number of overs for box cricket, tennis-ball games and short formats.

Tap 0 to 6 for runs off the bat. For an extra, tap Wide, No Ball, Bye or Leg Bye, then pick how many they ran. The 1-run penalty for a wide or no-ball is added for you.

For a wicket, tap WICKET, choose how they were out and who is out, then Confirm Out.

Yes. UNDO LAST BALL takes the last delivery back, and you can keep undoing ball by ball.

On the scoring screen, tap the share button at the top. It sends a link and the match's join code.

Anyone with CricStream can tap the link, or open the Live tab, tap Code and type the code in.

A YouTube channel with live streaming turned on. YouTube asks you to verify the channel with a phone number, and the first time it can take up to 24 hours before you can stream.

Then open the Stream tab, tap Connect YouTube and sign in with the Google account that owns the channel. Pick the live match, choose quality and privacy, and tap GO LIVE.

CricStream hasn't finished Google's verification for YouTube access yet. It is safe to carry on: tap Advanced, then Go to CricStream, and allow access.

CricStream uses that access only to run the live broadcasts you start.

Streaming needs a steady upload connection, roughly 3 to 6 Mbps for 720p. Move to better Wi-Fi or mobile signal, or pick a lower quality before you go live.

If the connection drops, CricStream reconnects by itself and shows RECONNECTING. If it can't get back within about a minute, it tells you and lets you try again or end the stream.

Streaming uses a lot of battery, so keep the phone charging, and mount it in landscape.

On Android, yes. Press Home, open another app or turn the screen off, and the broadcast carries on with its picture, sound and score ticker. A CricStream notification stays up while you're live; tap it to come back to the stream.

Leaving the app doesn't end the broadcast. To stop, come back to the stream and tap End Stream.

No. Video goes from your phone straight to your own YouTube channel. CricStream stores the match — teams, players and scores — not the video. The recording lives on your channel, where YouTube's own settings apply.

Open your Google Account's third-party access page and remove CricStream. Deleting your CricStream account also revokes the access.

Open Profile, then My tournaments, and tap + to create one. Add the teams, set up the fixtures, and score each fixture like any other match. The points table and player stats update as results come in.

A league (round robin, played once or twice), a knockout (with byes for the top seeds when the number of teams needs them), or groups followed by a knockout of the top teams from each group.

Every tournament has a 6-character code. Others open My tournaments, tap Join with code and type it in.

Yes. Scoring, following matches, tournaments and live streaming are free. The app shows ads, and you watch one short ad before a stream starts.

Not yet — CricStream is on Android through Google Play today.

Open Profile, scroll to the bottom, tap Delete account and confirm twice.

Your profile, photo and saved matches are deleted. Matches you scored stay visible to the players and followers who were part of them, but are no longer linked to you. The full details are in the privacy policy.

Use Report on the match, tournament or player page in the app, or email ravisfortune@gmail.com with the subject "Content report" and a link to or description of the content. See section 6 of the terms.

Your account details, the matches and teams you create, and — only if you turn it on — the location of a match. Everything is listed in the privacy policy.
