Sounds like your device maybe low on memory. Do you have an excess of text messages that could be deleted, maybe a large cache of pictures that could be deleted or uploaded to the cloud then deleted.
Another memory hog can be your mobile browser or other apps. Deleting cookies and other web junk from the browser could help free up memory. Cleaning your apps of data, at least those with large amounts you don't use may help. And just uninstalling unused apps too.
At least for Androids, there is an update available for the ibotta app too I noticed after typing the above two paragraphs.
