Not worth your time. Initially, I enjoyed using Ibotta and found it relatively easy and worthwhile. However, over time, the changes they have made to both the website and the app have made it totally impossible for me to access. You can no longer see either offers or your balance on the website, and they apparently have no plans to go back.
On my older iphone, I'm space-limited and am unable to download the latest version of the app (earlier versions are unavailable). I would only be able to download the app IF I changed the operating system on my phone - which I not only can't do due to space, but don't want to do just so I can use their app. Even though I explained my situation to Ibotta (I asked them to send my funds along to my PayPal since I no longer had any way to access their program), their only responses were: to ignore the circumstances, delay their response so as to deduct their non-use fees, tell me to download the app, tell me to change my operating system.
Any decent, consumer-friendly company would have a functioning website, make it possible for users to access the service via older versions of the app, be willing to understand how they have diminished access, understand the value of satisfied users, apologized and sent my credits along to PayPal. Instead, Ibotta insists on being consumer unfriendly, intransigent and seemingly more interested in imposing fees.
Stay away from Ibotta. Far away.
