Be carefull with product descriptions in the App Store. I bought Checklist Pro V3 (from Infodev Technologies) and found the product doesn't work with the Storm. It was listed as working in the App Store.
I reported the problem 5 days ago to the developer and haven't heard anything.
Also, the App store listed it as a $19 app, on sale for $9. On the Infodev web site it is listed at $9 regular price, and the storm is not listed as supported.
I also reviewed the product, and the review has not posted. Looks like the App Store doesn't allow negative reviews.
