Amar Batch is a pocket-sized register for private tutors and home-batch teachers. Mark attendance in under a minute, track fees, record exam marks, message parents by SMS, and ask an in-app AI assistant about your batch — sign in with Google, then subscribe with one tap via OTP.
Built for teachers running private tuition or small coaching batches — works fully offline for daily work, and backs up to your own Google Drive.
Select a class (and shift, if you teach it in multiple groups), tap the absentees, save. Calendar view shows every day you've taken attendance.
Set a monthly fee per class, collect for one or several months at once, and see who's due at a glance — every payment is snapshotted for accurate history.
Record exam results at the class level, enter marks by shift when needed, and share question papers with a Drive link.
Send admission, fee and result updates by SMS through our managed gateway — no SMS permission on your phone, just a prepaid credit balance you top up in-app.
Sign in with Google once and your data syncs to your own Drive automatically — change phones without losing a term's records.
A built-in AI chatbot answers questions like "who hasn't paid this month?" or "what's my profit so far?" using your own aggregated batch data.
One flat daily rate, billed straight to your mobile carrier balance. No card, no bank details, no separate account to manage.
Charging: 2.78 Tk/day (including VAT+SD+SC). Subscription is charged through your mobile carrier. For Robi and Circle users only.
This page talks to the same PHP relay the Android app uses. Enter a Robi (018) or Circle (016) number, request an OTP, verify it, and you're subscribed at 2.78 Tk/day (including VAT+SD+SC). No app install required.
Two-step: request an OTP, then verify it to activate your daily register subscription — 2.78 Tk/day.

In the app, you sign in with Google first — that instantly unlocks Drive backup. If your Google account isn't linked to an active subscription yet, you're asked for a Robi or Circle number to activate one by OTP. On the web, this page skips straight to the OTP step so you can subscribe or unsubscribe without installing anything. Every request goes through a small PHP relay hosted on our own server, which signs it with the application credentials and forwards the response back untouched. A separate listener receives status updates from bdapps directly.
The user enters their Robi or Circle number. The app posts it to the relay, which calls the bdapps OTP endpoint and returns a reference number.
send_otp.php → referenceNoThe user types the code they received by SMS. The relay forwards it with the reference number and gets back a subscription status.
verify_otp.php → REGISTEREDSubscription confirmed and linked to the teacher's Google account — attendance, fee tracking, exam marks, parent SMS and the AI assistant unlock in the app, and bdapps notifies our listener of any status change.
subscription_listener.php → S1000Number detection and OTP delivery are tuned for the two operators supported by this bdapps application.
The APK below is the current submission build. Android will warn about an unknown source since this isn't on the Play Store yet — allow the install to continue. Sign in with Google, then subscribe with your Robi or Circle number to start at 2.78 Tk/day.
