Beware of buying YummySoup! unless you only need the functionality it currently has working in the version you buy today. The developer has a history of making grand promises about future feature releases and delivering years down the track, or in a paid upgrade. If you're waiting for the accompanying iPhone app, then believe it when you see it before parting with your money because YummySoup! has always been two-thirds real and one-third vapourware. Don't buy everything you want really exists (and a few other people have written reviews to say they're okay and have all the promised functionality).
I've been using YS for two-and-a-half years, since I think version 1.3 or 1.4. There have been constant problems with stability, features in the release version that didn't work properly or at all (export, email), bugs not fixed, and by 1.9 - a version still plagued with stability problems and with many reported bugs unfixed, such as the title selection in the web importer causing selected text to disappear not import, or the tabbing through ingredients in a shopping list causing rows to revert to blank, keyword searches only search on titles... The dev had obviously long moved on to 2.0, to start the whole cycle again with a new group of licensees. Thank Ken, but your idea of a .9 release is not the same as mine - a place to leave a half-finished app while you work on the next paid upgrade.
Although the dev was always responsive to emails (I've dealt with worse), actual development moved at a snail's pace - years - and I gave up asking about fixes, even to some of the advertised features that were the reason I bought YS in the first place. I expect that he will take this review rather personally, and so he should - the defensive posture and the replies saying that YS is a one man band really illuminate the problem - the dev's ambitions and publicly-stated promises for the product are wildly out of sync with his capacity to deliver. Screenshots of YS 2.0 look nice, but actual functionality has barely improved - only the weekly planner and export functionality is new; other changes are either cosmetic or promised in future updates. YS 1.x was supposed to have export functionality, but Ken decided to save that for 2.0.
The reason this app does well is because its core functionality and idea are good -a streamlined recipe manager and import manager that copes well with importing from most websites. That really is its killer feature. But for groceries, planning, exporting, organising and sharing its features are basic at best, and the app really lacks the polish and professionalism you get from larger developers. If the price matched the reality and the app's ambitions were more modest, this could be a more reasonable purchase. But if you really want to use the YS to its limits, you may be disappointed. I suggest you check out all the recipe managers out there - there's plenty of good ones - and thoroughly test YS in your real-use situation. Don't buy because it looks nice, or because you're looking forward to iPhone integration. MacGourmet has all those features today, maybe give that a look. I still use YS 1.9 because it does everything I need, barely, but it's often exasperating. No more money will be spent on it until the fairy dust turns into something I can touch.
