Dekko was an in-development native email client for Ubuntu Touch when a July 13, 2015 report presented it as an example of Canonical’s desktop-convergence ambitions. The idea was that one application could adapt from a phone screen to a desktop context—not that Dekko had already become a finished desktop mail suite. It remains listed in the Ubuntu Touch OpenStore, though its current compatibility and reliability depend on the device, software version, and email provider.
What was Dekko?
Dekko was a native email application for Ubuntu Touch, intended to give the platform an on-device mail client rather than requiring users to rely on webmail in a browser. The 2015 report described it primarily as an IMAP client and identified it as the planned native email client for Ubuntu Touch. That was the project’s intended role at the time, not proof of a permanent or exclusive official status.
Dekko was based on Trojitá, a lightweight email client. That gave the project an existing foundation; the available account of its development does not specify which Trojitá components were retained, rewritten, or replaced. The report also described Dekko as open-source community software. Softpedia’s July 2015 report is the source for this historical description.
What “desktop convergence” meant for the app
In the 2015 Ubuntu context, convergence meant designing one application to work across different device situations, rather than simply shrinking a conventional desktop program onto a phone. The same app could, in principle, adapt its layout and controls to a narrow touchscreen, a larger display, and different ways of interacting. The report said developers were working to make Dekko function on desktop as well as phone.

That ambition should be distinguished from a demonstrated result. The report documents a design direction and development effort; it does not establish seamless phone-to-desktop continuity, identical behavior on every device, or feature parity with mature desktop email clients. Nor did Dekko create Ubuntu’s broader convergence strategy: it was one application intended to illustrate it.
Why email was a demanding convergence test
Email looks simple until an app has to serve both a phone and a desktop. On a phone, users need compact navigation and controls that work well with touch. On a larger screen, folders and messages may benefit from a multi-pane layout, while keyboard and pointer input change how people navigate and compose. A responsive layout is useful only if it preserves those different workflows.
The harder requirements are not purely visual. An everyday client also needs dependable account and identity management, message composition and attachments, folder synchronization, and sensible behavior on intermittent mobile connections. Background syncing and notifications matter especially when a phone suspends apps to conserve resources. Authentication adds another variable: a protocol such as IMAP does not guarantee that a provider will accept a particular client’s login method.
These are reasons email was a revealing test of convergence, not claims that Dekko had solved each problem in 2015. The contemporary report said new features were still arriving and that desktop adaptation was being worked on; it did not publish a test matrix or demonstrate production readiness.
What the July 2015 report actually established
The report was published on July 13, 2015, and described Dekko as beta software in an early stage of development. It mentioned code available through the core-apps PPA and said the app could be downloaded from the Ubuntu Touch store, while warning readers that it remained beta. Developer Daniel Chapman’s comments were presented in that early-development context.
Availability was therefore not the same as maturity. A beta could be installed and still be changing, incomplete, or unsuitable as a user’s only email client. Those statements describe the July 2015 snapshot; they should not be mistaken for the status of the current OpenStore listing.
Dekko’s current OpenStore listing
The OpenStore listing identifies Dekko as a convergent email client by developer Daniel Chapman and licenses it under GNU GPL v3. It lists version 0.5.2-24.04-1.x, an update date of October 2, 2025, and the architectures armhf, arm64, and amd64. These are listing details, not a complete compatibility guarantee: they do not establish that every Ubuntu Touch channel or device has identical packaging, or that a newer build is unavailable elsewhere.
The listing describes multiple accounts and identities, provider-specific setup options for some Google, iCloud, and Outlook accounts, and general IMAP and POP3 configuration. It also warns that some providers may require app passwords. These setup paths do not guarantee that every account will work: provider authentication rules can change, and the listing does not establish current OAuth support for every provider.

Such reports are anecdotal; the listing does not give a representative sample, device breakdown, or reproducible test results. They are reasons to test the app against your own setup, not proof that all users will encounter the same failures.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to try Dekko without risking your primary mail workflow
- Open the Ubuntu Touch OpenStore, search for Dekko, and confirm the developer and package details on the listing before installing.
- Start with a secondary or test account rather than moving your primary mailbox immediately.
- Configure the account using the provider’s current IMAP or POP3 requirements. If a normal password is rejected, check the provider’s guidance to see whether it requires an app password; do not weaken account security just to make a client work.
- Test receiving and sending, attachments, folder synchronization, and deletion. Confirm important changes—especially deletion—through the provider’s webmail before relying on them.
- If Dekko hangs after suspension, the OpenStore listing describes enabling a lifecycle exception in UT Tweak Tool so its background service can continue receiving signals. Treat this as a project-listed workaround, not a guaranteed fix; the interface may remain suspended.
One OpenStore review reports blank messages on Ubuntu Touch 24.04, and other reviews mention restarts or Google login trouble. These are individual reports rather than controlled findings. If a problem occurs, compare the app version and Ubuntu Touch release, check device logs where practical, and retain a fallback such as webmail.
Who should consider it—and what to expect
- A reasonable fit: Ubuntu Touch users who prefer a native, open-source app, have accounts that work with the available authentication methods, and are comfortable testing and troubleshooting.
- Use caution: Anyone depending on uninterrupted background sync, guaranteed access to a Google or Microsoft account, or a large set of complex mail workflows should verify those needs before relying on Dekko.
- Not established: The listing does not demonstrate full desktop workflow parity with established mail suites, enterprise readiness, or universal compatibility across devices and providers. An amd64 architecture listing alone does not make Dekko equivalent to a conventional desktop email application.
If account setup or reliability proves unsuitable, webmail is a straightforward fallback. Other possibilities include a desktop client such as Thunderbird in a supported desktop environment or compatibility layer, an Android mail app through Waydroid, or another Ubuntu Touch client. Those options involve different levels of integration and complexity; the available listing does not provide a like-for-like comparison.
Why Dekko still matters to the convergence story
Dekko’s significance is less about proving that it replaced desktop mail software and more about making the convergence challenge concrete. A single email app had to contend with changing screen sizes, touch and desktop input, account setup, network conditions, and background behavior. The 2015 report captured that ambition while the app was still beta; the OpenStore listing shows that Dekko remains available, alongside practical qualifications users should check for themselves.
