Tampon Timer is a free iPhone app developed by Daniel Lombardo that aims to help women stay fresh and prevent prolonged use of tampons. This simple alarm app allows users to set up reminders for changing their tampons.

To set a reminder, users simply need to enter the app, select the tampon product they are using, and choose a time for the reminder. When it's time to change, users receive a push notification alerting them to do so. The app also provides the option to dismiss the reminder or snooze it for 30 minutes, with the ability to adjust the snooze time in the settings page.

In addition to the tampon reminder feature, Tampon Timer includes a daily pill reminder that allows users to select a specific time to be reminded daily. This can be helpful for those who take contraceptive pills or other medication.

The app offers extra features such as a period calendar, where users can forecast their period, add events, and make notes. Users also have the option to receive notifications the day before or the morning of their period. Furthermore, the app provides a platform for users to review their period products anonymously, share their reviews with other women, and view highly reviewed products.

It's important to note that while the app provides information on the use of period products, users should always refer to the manufacturers' instructions for their specific products. The period/fertility/ovulation forecasts in the app may not be 100% accurate due to various factors affecting each individual's cycle. Therefore, it should not be solely relied upon for contraception purposes.

Overall, Tampon Timer is a convenient and user-friendly app that helps women stay fresh and keep track of their menstrual cycle. It offers useful reminders and additional features for managing period-related tasks.
