Diet & Exercise Assistant is an app I've used for over 7 years on the Palm platform (through several versions), and I've been begging and bugging the folks at Keyoe to release an iPhone version. They told me they were working on it a year ago, and I got an e-mail today that it was released, so I bought it and here's the review I wrote after checking it out: It's $9.99, and well worth it. Like it says in the review, I have tried just about every other diet tracker app in the App Store, and they all fell short of what I had grown used to with Diet & Exercise Assistant. I highly recommend it for anyone looking to keep track, lose (or gain) weight, or just have some idea of what they're doing food and exercise-wise. I've submitted a few feature suggestions already, but the app is solid and bug-free. I'm not affiliated with Keyoe, I just like their app.
