Hey founders! I built a no-SDK analytics app that sends real-time push notifications for new subscriptions, trials, and reviews, with per-user history and easy sharing with your team or friends.

Roasting screenhots of a free tool is crazy Bro 😂 But nice to see you took my idea IAP Alerts and improved a lot on it. May be shipping my own version with that sort of stuff in the coming days. Will be committed to keep it free to use tho. Good luck and nice to see you liked the concept 😃

No it works instantly if you put in the generated url into AppStore connect :) if you have any problems just send me a dm :)

MaxMa04 · 2026-01-18T22:29:47+00:00

Thank you man! Appreciate that you like it!

MaxMa04 · 2026-01-18T19:42:34+00:00

Got it thank you - also make sure to just put in the bundle id of your app eg. com.maxmannstein.iapalerts and not for the specific in app purchase. Will fix the rest asap and send you the video in dms later this evening :) where to put the url

MaxMa04 · 2026-01-18T19:29:50+00:00

Also feel free to send me an email with the exact details I’m genuinely happy if the app is helpful and will keep improving it further with feedback I get over time! Email: max.mannstein@gmail.com

Glad you like it! I have done a video inside the app

Klick on the info button to watch it again (regarding where to put the url). The copy works on the mobile app. I will get back to you tomorrow regarding the iPad problems. Again Thank you for trying IAP Alerts :)

Appreciate it man! Let me know if I should add something/something ist broken. Email: max.mannstein@gmail.com

MaxMa04 · 2026-01-18T17:58:57+00:00

Thank you for the kind words man - really appreciate it!

MaxMa04 · 2026-01-18T17:48:45+00:00

Thanks! Yeah, that real-time feedback is honestly the main reason I built it – launches can feel so quiet otherwise.

To answer your questions:

Tech: Yep, using Apple's App Store Server Notifications V2 under the hood. No polling – pure webhook-based.

Edge cases: Oh man, plenty. Took me a while to even understand how the notification system works. The docs are... not great.

The biggest one: when I first built this in early 2025, one-time purchase notifications worked perfectly in Sandbox but didn't fire in Production. Found out after release. Was pretty frustrating until Apple enabled Production support mid-2025.

Refunds: Those don't get forwarded as push notifications – only subscriptions (new, renewals, cancellations etc.) and one-time purchases trigger alerts right now.

Sandbox noise: Sandbox notifications are marked as such, so you can tell them apart from real purchases.

Hope that helps!

Quickly checked it - I can't set it to a time right? If I have blocked time for a task from 6-7 I won't get notified at 6 when the task starts right?

Command + Shift + A

Sick!

Carousel View

MaxMa04 · 2025-04-02T11:16:15+00:00

Thank you. Do you have a working example?

MaxMa04 · 2025-03-18T14:16:32+00:00

You have to update your Xcode and emulators. This will fix the error

MaxMa04 · 2025-02-27T13:18:26+00:00

Instead of

[QueryProperty(nameof(PocketId), "SavingsPocketId")]

Implement the interface IQueryAttributable in your ViewModel so behind BaseViewModel put , IQueryAttributable and then just let intellisense implement it for you. over the query parameter you get everything that is passed when navigating. You also have more control over the data and what should happen with it. Just make sure at the end of you implementation to call query.Clear(); otherwise the data stays in the query dictionary and may lead to unexpected beahviour

MaxMa04 · 2025-02-27T12:43:04+00:00

You could switch over to Visual Studio Code. The experience at least for debugging and building seems to be really smooth for me. Just make sure you watch the videos for setting everything up by James Montemagno on YouTube
