Hourly rates are controlled by the category you give a session. There’s a few ways to change rates. If you don’t want to change historical sessions, edit the category on your Mac/PC.

Edit an existing category

On desktop, choose Edit->Categories menu. Edit your category and assign a new rate. You’ll be asked if you want to apply it retroactively or just for new sessions. If you’re synced with a mobile device, it will update to respect whatever choice you chose here.

On mobile, tap Categories from the main screen. Tap Edit. Tap a category and change the rate. The new rate will be applied to all sessions.

Make a new category

Create a new category with your new rate.

On desktop, select the sessions you wish and click the category to change it for these sessions.

On mobile, tap a session and apply the new category.

Edit a session

On desktop, select a session and click on the money amount shown. You can set a rate for this session different from whatever category is assigned to it.
