Qaza Tracker was not built as a product. It was built because counting on paper does not work, and because nobody should have to guess at something this important.
Almost everyone who has missed prayers knows they have missed them. Very few people know how many.
That gap is where the problem sits. A person will resolve to start making up their qaza, pray a few, lose count within a fortnight, and quietly give up, because there was never a figure to work against in the first place. The intention was sincere. The method was the thing that failed.
One thing only: turn an unknown into a number, and then let that number come down. Everything else in the app follows from that. If a feature does not help someone see their total or reduce it, it does not belong here.
That is also why the app does the arithmetic rather than asking you to. Working out twenty two years of missed Isha by hand is not difficult, but it is the kind of small friction that stops people before they begin.
This app is given fi sabilillah, for the sake of Allah alone. It is sadaqah jariyah, an ongoing charity, and there is no worldly gain sought from it of any kind. Nothing is charged, nothing is advertised, nothing is sold, and there is no business sitting behind it waiting to be built.
The only return being sought is the one that comes after this life.
That is also why sharing it matters more than anything else you could do with it. A sadaqah jariyah grows by reaching people. Every person who starts counting because somebody passed this on, every prayer they make up as a result, carries weight for whoever pointed them here. Send it to your family, send it to a friend. It costs you nothing and it may be the most valuable use of it.
Early on the admin screen showed how many prayers each account owed. It was useful, and it was wrong. What a person owes is between them and their Lord, and no part of that belongs on somebody else's screen.
So it was taken out. Not hidden behind a permission, not tucked away in a different tab, but removed. The administrator can see that an account exists and when it was last used, and nothing more than that. The activity log was stripped of prayer figures as well, because a number leaks just as easily from a log as from a table.
An app that disappears when one person becomes unavailable is not an ongoing charity, it is a favour with an expiry date. So the app is built to outlast whoever is looking after it.
The aim is that anyone with the key and the files can put the app back up exactly as it was, for as long as people are still using it.
Nearly everything added since launch came from someone using it and asking. Separate tracking for prayers missed while travelling came from a single message. Qaza roza and missed sajdah tilawat came the same way, from people saying their prayers were being counted but the rest of what they owed was not. The app will keep evolving in exactly that way.
So keep telling us. If you would like a different colour scheme, if a screen is awkward on your phone, if there is a feature you think belongs here, or if something simply annoys you, say so. Every message is read, and the aim is always the same: make it easier and simpler to use.
The contact form is the only way to get in touch, and that is deliberate. There is no email address published and no individual to contact. What matters is the app, not who built it.
If the app is useful to you, passing it to somebody else costs nothing and may be the most valuable thing you do with it.
These pages explain what Qaza Tracker is. The counting, the recording and your own figures all live in the app, which opens once you log in and stays open until you sign out.
