Leak detection tools for technicians: what is in Kashf Pro and how to try it
A leak detection technician already carries listening equipment, a thermal camera and a pressure gauge. Even so, minutes are lost waiting on the water meter, listening points are compared from memory, and the customer report gets typed up by hand at the end of a long day.
This guide introduces Kashf Pro, a set of leak detection tools for technicians that runs in the phone's web browser. You will learn what each tool does, how the free trial starts, how plans, usage credits, renewal and cancellation work, and where the tools honestly reach their limits.
What is Kashf Pro and what does it do?
Kashf Pro is a web app (PWA) at /pro/app/. It opens in the browser and can be installed on the home screen on both Android and iPhone. It contains seven tools:
- 🎧 Acoustic Leak Listener: analyses leak noise and gives a score, an alert and a survey map. (its guide)
- ⏱ One-Minute Meter Leak Camera: calculates the leak rate from the meter's rotating dial using the camera. (its guide)
- 🌡 Thermal Image Analyzer: analyses a thermal camera image and the shape of the anomaly. (its guide)
- 🧭 Pressure Test Logger: photographs the gauge at intervals and plots the pressure drop. (its guide)
- 💧 Moisture Map: turns moisture meter readings into a map. (its guide)
- 🧾 Water Bill Analyzer: extracts the consumption history and flags jumps. (its guide)
- 📡 Two-Sensor Leak Correlator (experimental): locates a leak between two sensors. (its guide)
Every result can be saved as a report with a link you can share with your customer.
Who are these tools for?
When you sign up you choose the type of work you do: leak detection technician, leak detection and waterproofing company, engineer or consultant, property management, or other.
The platform is open to any technician, including those who work for another company. You do not have to be part of the Kashf team.
When do you use them?
- At the start of a visit: to prove there is a leak and measure its size at the meter, or to read the customer's water bill.
- During the search: to listen and survey, analyse thermal images, log a pressure test and map moisture.
- Before opening anything up: to document the suspected point with numbers and photos.
- After the repair: to take a second measurement that shows the leak has stopped, and to send the report to the customer.
Where do you use them?
On site, on your own phone. The app needs an internet connection to sign in, start a session, save results and run the AI image readings. Sound analysis and meter-dial tracking run on the phone itself.
Sign-up, purchases and subscription management happen on the website only. There are no in-app purchases through the app stores.
What do you need before you start?
- A Saudi mobile number (registration currently requires one) and a password of at least 8 characters.
- A modern browser, then permission for the microphone and camera when you open the tools.
- Optional equipment, depending on the tool: a contact microphone or ground sensor over AUX or USB-C, or the headphone output of your detection unit. For the correlator, a two-channel USB audio interface and two sensors. A thermal camera that exports images, a pressure gauge and a moisture meter.
- To pay: mada, Apple Pay or a card, depending on the payment methods enabled.
How to use it correctly, step by step
Kashf Pro — plans and subscriptionSubscription — free trial available
The Kashf Pro page lists the tools and the plans. For each plan the platform administrator sets:
- A monthly and a yearly price.
- A number of free days for new subscribers.
- A monthly limit for each tool. The limit is shown as a monthly number, as “Unlimited”, or as “—” when the tool is not included in the plan.
The page also states whether prices include VAT. Prices are managed from the admin panel, so the reference is always what the plans page shows at the time you buy.
Usage is counted per session. The first use of a tool opens a session that stays valid for a set time. Within it you can repeat a measurement or a recording without another deduction. Usage is taken from your plan's limit first, then from your usage credits if you have any.
Credits are a bundle of uses you can buy without a subscription, with a stated validity period.
Steps for correct use
- Create your account
On /pro/ tap Start free, or open the app and choose Create account. Enter your name, your mobile number in the 05xxxxxxxx format, your company and city if you wish, your type of work and a password of 8 characters or more. If you have a coupon, enter it in the coupon field. Then accept the terms and tap Create account.
- Confirm your number and start the trial
If the messaging channel is enabled you receive a verification code to enter. The free trial then starts automatically. It is available once per mobile number and needs no card. Some coupons add extra free days, and you may receive a reminder before the trial ends if messaging is enabled.
- Try the tools and watch your limits
The home screen shows the tools, each with a badge underneath: N left, Unlimited or No subscription. Under My account you see this month's usage per tool, for example 4 / 30, and any credits you hold. When you reach a limit, a “You need a subscription or credits” window appears.
- Choose a plan and billing period
Under Plans, switch between Monthly and Yearly and compare the limit for each tool. Then tap Subscribe. If you only need one tool now and then, a bundle of usage credits from the same section, bought with the Buy button, may be enough.
- Choose how to pay and finish
In the Checkout window choose Pay for the period upfront with mada, Apple Pay or a card, and you will receive a renewal link before it ends. Or choose Automatic card renewal, which you can stop at any time. Add a coupon if you have one; coupons work with upfront payment only. Accept the terms and tap Continue to payment.
- Manage your subscription and results
My account shows your plan, its status, its end date and how it renews, and it is where you tap Stop automatic renewal. Under My saved results you can open or delete reports. You can also delete your account and all its data permanently using your password.
How to read the result
Subscription statuses as they appear in the app:
- Free trial.
- Active.
- Payment overdue (grace period): a few days after expiry to renew an upfront plan.
- Expired.
- Cancelled.
Renewal:
- “Automatic by card”: charged at the start of each period.
- “Stopped — ends on schedule”: you turned renewal off and the subscription runs until the end of the paid period.
- “By payment link before expiry”: upfront payment, and nothing is charged unless you pay.
Upgrading to a higher plan takes effect immediately. The value of the time left on your previous paid plan is converted into extra days, and the old automatic renewal is cancelled to prevent double charging. Downgrading is not possible while a paid higher plan is still running; the comparison uses the price of the billing period you choose (monthly against monthly, yearly against yearly). Stop renewal and wait for it to end. Renewing the same plan adds the new period to the end of your current one, so you lose nothing.
If a coupon covers the full amount, the plan is activated immediately with no payment.
Installing the app and granting permissions
- Android (Chrome): open the app, then from the three-dot menu choose “Add to Home screen” or “Install app”.
- iPhone (Safari): tap the Share button, then “Add to Home Screen”.
- Permissions: the browser asks for the microphone for the sound tools, the camera for the meter, pressure and moisture tools, and the compass on iPhone. If you refused once, allow it again from the site settings in your browser.
- External devices: after plugging in a microphone or an audio interface, reopen the audio input list inside the tool so it appears by name.
Reports and privacy
When you save a result you get a report link that you can open or send to your customer. It contains the numbers and images you chose to save, such as the survey map, the spectrogram or the meter photo. Depending on the platform settings, a short line introducing Kashf Pro may appear at the bottom.
- Audio is analysed on your phone and is not uploaded. Only what you ask the AI to analyse, such as the spectrogram image, or what you save, is sent.
- Repeated reading photos from the pressure and moisture tools are not kept on the server once they have been read.
- Deleting your account from “My account” permanently removes the account and its results.
Full details are in the subscription terms and privacy policy.
Where does AI come in?
Some tools read images with computer vision:
- The temperature scale in a thermal image.
- The display of a pressure gauge or a moisture meter.
- The consumption table on a water bill.
- An optional review of the spectrogram in the Acoustic Leak Listener.
These readings only work when an AI provider is connected to the platform. If none is available, a message says so. The final figures, such as scores, jumps and the rate of pressure drop, are calculated with fixed formulas. The AI only reads and describes.
Each session has its own cap on AI analyses; once it is reached, a new session starts.
Common mistakes
- Opening tools in the office just to try them: every tool opens a session that counts against your limit. Try them on a real job or within a single session. (The listener does not count a session before microphone access is granted, the correlator does not count one before a valid two-channel recording, and one pressure test counts as one use for its whole duration.)
- Buying a bigger plan than you need: check each tool's usage in “My account” after the trial month, then decide.
- Expecting an immediate downgrade: not possible while a higher plan is running. Stop renewal and subscribe to the lower plan after it ends.
- Trying a coupon with automatic renewal: coupons work with upfront payment only.
- Sharing your account: the terms forbid selling or publicly sharing it, and limits are counted per account.
- Sending a report without checking it: review the numbers and settings, such as speed and litres per revolution, before you share the link.
The honest limits of the tools
- The tools measure, analyse and suggest; they do not replace a field inspection or your experience. The results support your judgement and do not replace it.
- Accuracy depends on the quality of your phone, its microphone and camera, the background noise on site and correct settings.
- A single phone microphone cannot tell the direction of a leak. Surveying by comparing points is the realistic method.
- The two-sensor correlator is experimental and needs a two-channel audio interface and two separate sensors.
- Image-based analyses need an AI provider to be connected.
- The algorithms were tested on simulated signals and images, and field performance can differ.
- Refunds follow the published terms. Read them before you pay.
When to escalate or ask for a second opinion
The tools speed up your work, but some cases go beyond one technician and one phone:
- Results conflict between tools, or the leak seems to move between several lines.
- A long buried line under expensive flooring that needs confirming with tracer gas before digging.
- Cracks, visible rust on reinforcing steel or a sinking floor. These need a licensed structural engineer before anything is opened up.
- Water near electrical installations. Safety first: switch off the power.
- A customer who needs a report from a detection company to submit to the water utility or an insurer.
In these cases you can request a second opinion or subcontract the Kashf team, which works in Saudi Arabia. The team detects leaks electronically without breaking, using acoustic and thermal equipment, pressure testing and tracer gas, and hands over a written report that can be checked on the verification page. Book from the order page or on WhatsApp at +966544027180.
Frequently asked questions
Are these leak detection tools for technicians free?
They start with a free trial, available once per mobile number with no card, on the plan and number of days shown on the plans page. After that you choose a monthly or yearly subscription or buy usage credits. Prices are set by the platform administrator and are shown on the plans page when you buy.
Can I subscribe if I work for another leak detection company?
Yes. The platform is open to all leak detection technicians, companies, engineers and property managers, and you do not have to work with the Kashf team. You choose your type of work when you sign up, and the account belongs to you or your business.
How do I cancel automatic renewal?
In “My account” tap “Stop automatic renewal”. Your subscription stays active until the end of the paid period and then ends without another charge. If you pay upfront there is no automatic charge at all; you receive a renewal link before expiry and pay only if you want to continue.
Why can't I buy through the Apple or Google app stores?
Purchases are made on the website only, with the payment methods enabled there: mada, Apple Pay or a card for upfront payment, and a card for automatic renewal. The app itself runs in the browser and installs on your home screen without an app store.
What is the difference between a subscription and usage credits?
A subscription gives you a monthly limit for each tool for as long as it runs, and some tools may be unlimited. Credits are a number of uses you buy once without a subscription, valid for a stated period, and used after your plan's limit runs out or on their own if you have no plan. Credits suit occasional use.
How is usage counted? Does every tap reduce my limit?
No. The first use of a tool opens a session valid for a set time, and within it you can repeat a measurement or recording without another deduction. AI analyses inside a session have their own cap. When the session ends, your next use counts as a new session.
Can I move down to a cheaper plan?
Not while a paid higher plan is still running. Stop automatic renewal, and when the period ends subscribe to the lower plan. Upgrading to a higher plan, on the other hand, takes effect immediately, and the value of your remaining time is converted into extra days.
Do you keep audio from job sites or photos of customers' homes?
Sound analysis happens on your phone and is not uploaded. Repeated pressure and moisture reading photos are not kept after they have been read. Only what you choose to save in a report is stored, and you can delete any result, or your whole account, permanently from “My account”.
Do the tools replace professional leak detection equipment?
No. They add analysis, documentation and speed to the equipment you already have. You can connect your detector's headphone output, analyse images from your thermal camera and document a pressure test. The final call still rests with your experience and the field test.
I forgot my password. How do I get back in?
On the sign-in screen tap “Forgot password” and enter your mobile number. If the messaging channel is enabled you receive a code to enter together with a new password. If it is not enabled, a message explains that recovery goes through support, so contact them.
This guide is educational. It explains estimation tools that help you understand a situation and decide what to do next; confirming a leak and pinpointing it always requires an on-site inspection with instruments. Structural questions are for a licensed engineer to decide.
