Comparison
Blink is British, very much a mobile app for the frontline workforce, with a long track record in healthcare and transport. They publish their price, which is to their credit, and that means you can actually compare. Here it is row by row.
Of 10 rows, Blink wins 2 and we win 5.
Blink is a British company focused on the frontline workforce: nursing, transport, retail, people who work standing up and without a computer. Their product is built around a well-made mobile app, with a feed and a document repository.
They're one of the few competitors who publish a per-person price on their website. That means you can compare without asking for a quote, and we'll give them credit for it.
Row by row
Blastack
€1.00 per person per month for the base plan, plus ten modules costing between one and ten cents each: with all of them switched on, €1.28.
Blink
They publish a per-person, per-month price in dollars, across three plans. They're one of the few who do.
Blastack
€1.00 for the base plan, or €1.28 with all ten modules switched on.
Blink
Their entry plan is $3.75 per person per month and the next one $5.00; they also publish a euro price, €3.35 and €4.20. All four are the annual-payment figures: month to month costs more. Check today's number on their site, but that's the order of magnitude.
Blastack
No app in the stores: you pin it to the phone's home screen from the browser.
Blink
A well-built native app, which is the centre of their product and their biggest strength.
Blastack
Reach per post and per department, sorted by whoever it reaches least. A two-cent module per person per month.
Blink
Their analytics layer is a separate paid add-on, on all three plans. Count it in when you compare prices.
Blastack
Single sign-on with the company account over OpenID Connect — Microsoft Entra ID, Google Workspace and Okta — plus SCIM 2.0 provisioning, so joiners and leavers arrive from your HR system on their own. It's the corporate identity module at two cents per person per month, not a reason to move you up a plan. There is no SAML, and that is a decision rather than a gap: SAML is signed XML, verifying it properly means XML canonicalisation, and that is where most of the authentication bypasses of the last decade have come from. If your tender requires SAML 2.0, we lose this row. Worth keeping the scope in mind either way: most of your workforce has no account in the corporate directory at all, so single sign-on covers the office and the joining codes cover the shop floor.
Blink
SCIM from their middle plan up, which is the $5.00 per person one: to get automatic provisioning you have to move up a plan. Ask them which protocols they support, SAML included: that is the one we do not cover.
Blastack
Interface in twelve languages — English, Spanish, Catalan, Portuguese, French, Italian, German, Swedish, Dutch, Polish, Romanian and Czech — and posts in those same twelve: each person sees the whole app in theirs. There is no machine translation: whoever publishes writes every version.
Blink
Multilingual.
Blastack
Export of the content and the workforce, with the deadlines in writing.
Blink
Exporting the workforce is straightforward, in Excel. Exporting the posts isn't: their feed API is write-only, and the documented route to pull the text out in bulk goes through their paid analytics add-on. Comments download as CSV one post at a time, and you have to ask them to switch that on.
Blastack
Export and deletion deadlines written into the Article 28 data processing agreement.
Blink
Their data processing agreement says "delete or return Customer Personal Data and copies thereof to the Customer on termination of the Agreement" the personal data within 30 days of the request, and the one who chooses between the two is Blink. Worth a written question before you sign.
Blastack
Our own servers in the European Union, no transfers outside the EEA, with the GDPR Article 28 data processing agreement.
Blink
A British company. Since Brexit the UK sits outside the European Union, though with an adequacy decision running in both directions. What they don't publish is where the data is actually held or who the sub-processors are: ask, and get it in writing.
Blastack
None. We don't have ISO 27001 and we don't have SOC 2.
Blink
A larger company with public healthcare customers; ask what they hold today.

The Blink figures are the ones they publish on their website, in their developer portal and in their contract, checked in August 2026. They change, and we are not a neutral source: check them with Blink before you decide anything.
No spin
If any of these three is what you need, go with them. We would rather lose here than six months in.
It's the best thing they have and that needs saying. It's built for someone who opens it for thirty seconds between two tasks, and it shows. We do the same job from the browser, and it works, but a native app alerts people better.
They have a lot of mileage in hospitals and in fleets, with the particulars of those two worlds already solved. If that's your sector, they'll understand your problem before you've finished explaining it.
Certifications, and a track record with the buyers who ask for them. Automatic provisioning and single sign-on we do have now, though only over OpenID Connect: SAML 2.0, ISO 27001 and SOC 2 we don't, and those are the rows that decide a tender.
Our side
Because we both publish a price, the comparison is direct instead of being a conversation. With analytics included on our side and a paid add-on on theirs, the difference per person per month is several times over.
Having the only route to your own announcements run through a paid analytics module is the kind of detail you don't see at signature and feel heavily on the way out. Ask about it up front, whoever you're buying from.
Our own servers in the European Union and deletion deadlines in writing. With a supplier who doesn't publish where the data sits, that conversation with your employee representatives and your data protection officer is a longer one.
