Recommendations from your network
Need an electrician, a photographer or a tax advisor? Just describe what you need help with. WhoKnows shows you the right people from your own and extended network.
WhoKnows is an app that helps you find service providers, experts and other helpful contacts through your personal network.
You need an electrician. A photographer. Help with your taxes.
So you ask in five WhatsApp groups or search Google for strangers.
Yet the right person may already be in your network.
WhoKnows shows you who can do what.
WhoKnows shows you who from your address book is already on board and what they can do – without names or numbers ever leaving your phone in plain text.
Just type “Who can fix my lamp?”. WhoKnows understands that you’re looking for an electrician.
Call or message via WhatsApp or text – someone you know instead of a stranger.
One example, from question to help.
Your new ceiling lamp should finally go up. You need an electrician.
You type into WhoKnows: “Who can fix my lamp?”
WhoKnows finds Ethan. He’s one of your contacts – you just never knew he’s an electrician.
Anna knows you both and gave Ethan five stars: “Quick, tidy, super friendly.”
You message Ethan directly on WhatsApp. By the weekend, the lamp is up.
More than 100 professions and talents, from trades to taxes.
See at a glance who from your address book is on WhoKnows and what they can do: electrician, tax advisor, photographer, web developer and much more.
Describe what you’re looking for in your own words. WhoKnows figures out which profession fits and shows you the right people from your network.
No specific plan? Swipe through the profiles in your network without a search term and filter by categories like trades, design or finance.
Ratings come from real contacts instead of anonymous strangers. Get in touch directly by phone, WhatsApp or text.
Add your skills and a few words about yourself. That way your contacts find you when they need help.
To find someone, that person has to be on WhoKnows – but not your whole address book. A few contacts are enough, because each of them brings their own network.
Everyone from your address book who uses WhoKnows – with what they can do and ratings from your mutual contacts.
They get nothing from us – no texts, no invitations. We don’t even remember that they’re in your address book.
Yes, with one tap via WhatsApp, text, or as an image for your story or group chat. You decide who to invite.
Faster than you think: five friends who each have 20 contacts on WhoKnows bring you up to 100 people in the 2nd degree – and their contacts add the 3rd degree.
You immediately see who from your address book is already on board and how many more people there are in your extended network. If nobody’s there yet, you invite the first people right from the app.
You know Lisa. Lisa knows Tom. Tom is an electrician. Tom is your 2nd degree contact.
For free, you see that there are people in your extended network who can help. With WhoKnows Pro you see that it’s Tom – and that Lisa can connect you. One tap asks Lisa for an introduction. This works up to the 3rd degree.

WhoKnows is built on trust within your network. That’s why you decide who sees what about you.
Numbers and email addresses from your address book are turned into checksums (SHA-256) on your device. We never receive names or plain-text numbers.
Your direct contacts see you – they already have your number. Contacts of your contacts only see your name, photo and number if you allow it.
We don’t show ads and don’t sell data. You can delete your account anytime, right in the app.
WhoKnows is a networking and recommendation app for iPhone and Android. Users describe what they need help with, and WhoKnows finds the right people from their own or extended personal network – from electricians to tax advisors.
A few are enough, because each contact brings their own network. For free, you see how many more people are in your extended network; with WhoKnows Pro you also see who they are. You can invite contacts without WhoKnows with one tap via WhatsApp or text.
WhoKnows is free. If you also want to find 2nd and 3rd degree contacts, you can add WhoKnows Pro for €3.99 a month or €19.99 once.
Your direct contacts – people who have your number or email address in their address book. Contacts of your contacts only see your name, photo and number if you allow it under Profile → Privacy. Otherwise they only see your skills and can reach out to you through your mutual contact.
No. Phone numbers and email addresses are turned into checksums right on your phone. Our server only compares these checksums and remembers which WhoKnows users are in your address book – nothing about your other contacts.
No, it’s optional. Without access, however, WhoKnows can’t show you who from your circle is on board. You can change the permission anytime in your phone’s settings.
You write what you need help with, and WhoKnows maps it to the right professions – “my tap is leaking” becomes plumber, for example. We use AI for this; it only receives your search text and profession names, no names or contact details.
1st degree are your own contacts. 2nd degree are the contacts of your contacts, and 3rd degree are their contacts. Example: you know Lisa and Lisa knows Tom – so Tom is your 2nd degree contact. With Pro you see who connects you and can ask for an introduction.
Of course. Add what you can do to your profile – for work or in your free time. Then your contacts find you when they’re looking for exactly that.
Right in the app under Profile → ⋯ → Delete account. All steps and what gets deleted are explained here.
Free for iPhone and Android, in English and German.
