Apps by Muhammad Shahid Khan · Updated 12 September 2026
This page supports every iPhone and iPad app published by Muhammad Shahid Khan on the App Store. Whichever app brought you here, the address below reaches the person who built it.
Contact the developer
Email contacttoshahidkhan@gmail.com — every message is read and answered by the developer, usually within two business days. Bug reports, feature requests, corrections and refund questions all go to the same address.
To get a useful answer on the first reply, include: the name of the app, your device model, your iOS version, what you tapped, and what happened instead of what you expected. A screenshot or screen recording helps more than anything else.
Find your app
Every app published under this developer account is listed on the App Store, with its current version, release notes and what it requires:
Common questions
The app crashes, freezes, or a screen is blank
Work through these in order — one of them fixes it nearly every time:
- Force-quit the app (swipe up from the bottom, then swipe the app away) and reopen it.
- Check the App Store for an update; a fix may already be released.
- Restart the device.
- Delete and reinstall the app. Note that anything you saved in the app is stored only on your device, so reinstalling starts it fresh.
If it still happens, email the app name, your device model, your iOS version and what you were doing when it happened. That is usually enough to reproduce and fix it.
A feature asked for a permission. Do I have to allow it?
No. Each permission is requested only when you open the feature that needs it, never at launch, and declining affects only that one feature — the rest of the app keeps working. You can change any of them later in iOS Settings, by finding the app in the list. What each permission is used for is set out in full in the privacy policy.
Where is my data stored, and how do I delete it?
On your device, and nowhere else. There is no account, no sign-up and no server holding a copy, so there is nothing to close and no one to ask. Deleting the app deletes everything it stored — saved items, notes, history, results and settings — permanently.
How do I turn off personalised ads?
In apps that show ads: iOS Settings → Privacy & Security → Tracking, then turn off tracking for that app. You will still see ads, but they will not be personalised. In the EEA and UK, your choice in Google's consent form governs this, and you can reopen that form from the app's settings screen where one is offered.
Can I pay to remove the ads?
It depends on the app. Where an app offers a paid tier or in-app purchase, it is shown on its App Store listing and inside the app. Where it does not, the app is free in full — every feature available to everyone — and advertising is how it pays for itself.
I want a refund, or I was charged for something
All purchases and subscriptions are handled by Apple, not by us, so refunds go through Apple at reportaproblem.apple.com. Subscriptions are managed in iOS Settings → your name → Subscriptions. If something looks wrong on our side, email and it will be looked into.
Something in the app is wrong or out of date
Send the app name, the exact screen or entry, and what it should say. Corrections are taken seriously and go out in the next update; if something cannot be verified, it is removed rather than left wrong.
Can you add a feature, or support my language?
Requests are welcome and genuinely shape what gets built next. Email what you need and why — the reason matters as much as the request.
The app is not available in my country, or will not install
Check the App Store listing for the minimum iOS version and device requirements. Apps are published worldwide wherever the App Store allows; if one is missing in your country, email and it will be checked.
How do I report a privacy or security concern?
Email the same address with "security" or "privacy" in the subject line. Security reports are answered first, ahead of everything else.
Still stuck
Email contacttoshahidkhan@gmail.com with the app name, your device model and your iOS version. There is no ticket system and no bot — the reply comes from the developer.
