Paper issue slips and a purchase-request spreadsheet mean nobody knows the real stock, and requests get lost between departments. Describe your warehouse and who requests and approves, and whacka builds a phone app: department heads request materials, the storekeeper issues them once approved and the stock drops, and a purchase order goes nowhere without the manager’s approval.
Only the storekeeper changes quantities, stock never goes negative, and every item keeps a movement log nobody can edit — who, how much, when. When an item falls below its minimum, the storekeeper and the manager are alerted. Free to start; free apps stay online for 14 days after each publish, and paid plans start at $3 a week.

Makhzoonna — a factory warehouse with two departments
Built from the message below — written in Jordanian Arabic — in about eleven minutes; Whacka asked one question first (how do staff sign in?) and the answer was “username and password”. Open it and tap «جرّب التطبيق بدون حساب» (try it without an account): approve a materials request as the department head, issue it as the storekeeper, and approve a purchase order as the general manager.
بدي تطبيق للمستودع وطلبات الشراء بمصنعنا. عنا قسمين: الإنتاج والصيانة، كل قسم إله رئيس، وعنا أمين مستودع. - أمين المستودع هو الوحيد اللي بيسجّل الوارد والصادر وبيعدّل الكميات. - الكمية بالمخزون ممنوع تصير بالسالب، وما منصرف أكتر من الموجود. - إذا صنف نزل عن الحد الأدنى بيوصل تنبيه لأمين المستودع ولإلي. - رئيس القسم بيقدّم طلب صرف مواد لقسمه، وأمين المستودع بيصرف بس بعد ما يوافق رئيس القسم. - طلبات الشراء: رئيس القسم بيقدّم طلب شراء، وأنا (المدير العام) بس اللي بوافق أو برفض. بعد ما أوافق ما حدا بيقدر يعدّل الطلب. - لما توصل البضاعة أمين المستودع بيسجّل الاستلام والكمية بتزيد. - الموظفين العاديين بيشوفوا الأصناف والكميات بس، ما بيشوفوا سعر التكلفة. - كل صنف إله سجل حركات: مين وإيمتى وقديش، وما حدا بيقدر يعدّل هالسجل. - رئيس القسم بيشوف طلبات قسمه بس. - أنا بعمل حسابات الموظفين باسم مستخدم وكلمة سر. التطبيق بالعربي.
- We signed in as every role with real accounts and also called the server directly: only the storekeeper changes quantities, and stock never goes negative
- Only the general manager approves purchase orders, which lock once approved; issuing and the stock deduction happen together
- Ordinary staff can’t see cost prices, and an item’s movement log can’t be edited by anyone
- In demo mode: issuing 5 kg took an item from 61 to 56, and receiving an approved purchase took another from 38 to 138
What you can build
Describe any of these — whacka builds it.
Good to know
Is it free?
Free to start: the free plan gives 8 credits a day (up to 24 a month) — enough to build, refine and publish a first app, with no card. On the free plan a published app stays online for 14 days after each publish; paid plans start at $3 a week or $10 a month. Running the app itself — data, storage, notifications — uses no credits.
How many staff logins can I create?
You create them yourself inside the app — a username and password per person, no email needed. They count against your Whacka account: 5 on Free, 10 on Starter, 30 on Pro and 100 on Ultra; for more, email wow@whacka.app.
Are the permissions real, or just hidden buttons?
The core rules in these apps — who sees what, who approves, and locking a request once it is approved — run on the server itself, not just on the screen. We tested them with real accounts for every role and tried to reach the data directly, behind the screens; what held is listed under the app above. When you build yours, spell out who sees what and who approves what, the way the message does.
How is this different from a shop inventory app?
A shop inventory app tracks sales, purchases and stock counts for one owner. This is a warehouse with several roles — who requests, who approves, who issues — and each role sees and does only its own part.
Do the alerts reach the phone?
The app sends a push notification to the storekeeper and the manager when an item falls below its minimum, once each of them has added the app to their home screen and turned notifications on; on iPhone, notifications don’t arrive before that step.
