Pricing and value
Both apps start free. The difference is what free gets you. WishApp keeps every feature free, with no subscription, ever. WishUpon's free tier caps you at 1,000 saved items a month and three pinned items, then asks $1.99/month for notes, unlimited lists, and a purchased-items list. Worth knowing: that subscription doesn't remove the ads on Android. So you can pay WishUpon and still see ads.
Platforms and devices
WishUpon covers the basics: an iPhone app, an Android app, a web app, and a Chrome extension. That's it. No Firefox, Safari, Edge or Opera extension, no Raycast, and no tablet layouts, so an iPad or Android tablet runs the phone-scale app. WishApp reaches further: iPhone, iPad, Android phone and tablet, macOS, plus extensions for Chrome, Edge, Firefox, Opera and Safari, and a Raycast add-on. Same list, wherever you are.
Sharing, privacy and reservations
Here's where the gap shows. WishUpon lets friends view and reserve without an account, which is the right call. But shared lists reportedly don't show prices, so gift-givers click into every item to check. Its Secret Mode, the feature that keeps the surprise, is repeatedly reported as hard to find or broken. WishApp shows prices on the shared view, generates a QR code, and hides reservations from the owner natively. WishApp also runs no ads and sells no data, while WishUpon's App Store disclosure says it tracks you across other companies' apps.
Gifting and group features
For a personal save-for-later list, WishUpon is fine. For coordinated gifting, WishApp does more. It runs Secret Santa, lets a few people co-manage one list, warns you when an item is already saved, and tracks what you've reserved and received with a note like 'from Sarah'. WishUpon has none of that: no Secret Santa, no collaborative editing, no duplicate detection. One reviewer reported deleting a single duplicate wiped their whole list of 163 items.
Price tracking and adding items
This is WishUpon's real edge. It tracks price drops and pushes an alert when a saved item goes on sale, plus an in-app browser for shopping without leaving the app. WishApp doesn't track prices at all, so if waiting for a sale is your main goal, WishUpon wins that round. On adding items, both grab a product from a pasted link. WishApp also auto-fills the title, image and price, and saves in one click from the browser extension. WishUpon's price alerts, though, draw repeat complaints that they stop firing.
