The most famous is the clipboard one (https://ditto-cp.sourceforge.io/). I'd be surprised if they were referring to another "Ditto" software. - Source: Hacker News / 3 months ago

I use Ditto (https://ditto-cp.sourceforge.io/). It uses about 5MB Ram and lets you expire clips. - Source: Hacker News / 5 months ago

Ditto works well for me. If you have a cloud based file storage service like Google Drive or Dropbox, put the ditto database file in that folder and you'll also have an auto backup. Source: 7 months ago

For example: the wonderful Ditto Clipboard Manager is both an old-style .msi installer here https://ditto-cp.sourceforge.io/, but it is also on Crapstore here: https://apps.microsoft.com/store/detail/ditto-clipboard/9NBLGGH3ZBJQ?hl=en-us&gl=us. Source: 12 months ago

For a period tracking app, you can use Clue. They also has many well researched articles on the female reproductive system on their app and their website Hello Clue. Source: about 1 year ago

Here's the website, they have an Apple version too: https://helloclue.com/. Source: over 1 year ago

I came up with the various symbols myself; for fertility stuff my first thought would be to look at what Clue is using these days, if you're drawing a blank (as it were) on anything! Let me know if you'd like to see a more recent/more filled-out version :). Source: over 1 year ago

Can’t vouch for the efficacy because I haven’t used the feature, but the cycle tracking app I use clue has a new birth control feature that’s FDA cleared. it’s by far my fav tracking app and i’ve been a loyal user for years now, so i’m sure their BC function is good too. Source: over 1 year ago

Please check out Clue App on Android and iPhone. This app refuses to sell data and will keep you safe. It's already used by 12 million people, make the number higher! Source: almost 2 years ago
