The report card
Best for freehand sketching with other people
Limnu is a freehand whiteboard with markers, shapes and stylus support, in a browser and on iOS. Exports capture only the visible area, team controls need the $8 Team plan, and the Slack integration is not available right now.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | Pro is $5 a month billed monthly or $50 a year, at the edge of the cheaper quarter ($5.00). Team is $8 a seat. |
| Free plan and trial | B | The free plan has unlimited collaborators and boards with no cap on the page, limited admin controls and 30 minutes of video. A 14-day test drive of paid features comes first. |
| Features | C | Freehand drawing, leading mode, file markup and an API. Gap the listing shows: export is the visible area only, like a screenshot, not the whole board. |
| Ease of use | C | No store rating on record. You draw everything yourself and decide how to lay out the board. |
| Platforms and integrations | B | Web and iOS. The Slack integration is described as being upgraded and unavailable, and there is no Android or desktop app. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Limnu is for

Keep it
Nothing Limnu does is plain enough to make in a weekend. The 4 things listed below take a company.
It costs $60 a year.
What you could not
- An endless canvas that stays smooth with hundreds of things on it.
- A real app for iOS. Something home-made would be a web page.
- Several people working in it at the same moment.
- It plugs into other products, Slack among them, and has an API.
What this rests on. Limnu’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
