The desktop and mobile apps are native shells packaged from the same SvelteKit app — identical features to the web version, with shared accounts.
For platforms not yet released, use the web version — no install, no sign-up required to try it.
One Tutu ID signs you in across the whole suite — messages sync across devices in real time and are never lost.
