Tools that do one thing

The everyday utilities you search for and then have to fight through ads to use.

• Password maker
  A strong password in short readable chunks, like the ones Apple suggests, with an honest measure of how hard it is to guess.
• Photo shrinker
  Make a photo small enough for an email or an upload form that keeps rejecting it, and leave behind the hidden note of where it was taken.
• QR code maker
  A QR code that joins a Wi-Fi network, saves a contact, opens a link, fills in a bank transfer — or just holds your text.
• Random picker
  Flip a coin, roll dice, pick a number or draw names from a hat. Every outcome is exactly as likely as every other.
• Screen test
  Full-screen test patterns for a new monitor, phone or TV: dead pixels, uneven light, banding, ghosting and how many pictures a second you are really getting.
• Frequency analyser
  Listens through your microphone and shows which pitches are loudest, live, with the frequency and musical note of the strongest one.
• Surround sound test
  Play a sound from each speaker in turn, or send it circling round your head, to check headphones, stereo, 5.1 and 7.1 systems.
• Tone generator
  Play a tone, a sweep or noise through the left, right or both speakers, to test speakers, headphones, rooms and hearing.
• Word counter
  Words, characters, sentences and reading time for any text, and whether it fits a text message, a post or a search result.
