[ENGLISH] RooTelegram — A lightweight and responsive Telegram client for SailfishOS
RooTelegram is tested on:
- Sony Xperia 10 III (SFOS 5.0)
- Jolla C2 (SFOS 5.1.0.8)
This application was developed using artificial intelligence technologies, specifically Warp Terminal and Claude Code Opus. Therefore, if the use of an application generated via a large-scale language model (LLM) is not comfortable for the user, it is recommended to avoid its installation and use. It is specified that any negative comment regarding this circumstance will not only be ignored but will result in the immediate blocking of the user.
I hereby disclaim any and all responsibility for the application, its functionality, and any consequences arising from its use. By choosing to use this application, the user acknowledges and accepts that they do so entirely at their own risk, and agrees that the developer shall not be held liable for any damages, losses, or adverse effects—whether direct, indirect, incidental, or consequential—resulting from the use or misuse of the application.
Main features
- Simple, fast interface optimized for SailfishOS
- Full support for message formatting (bold, italic, monospace, etc.)
- Reliable notifications via a dedicated daemon
- Custom Emoji support
- Message PIN management
- Stickers support
- Group join request management (for admins)
- Modern UI + daemon architecture, for instant app startup
Project origins
RooTelegram was born as an evolution and modernization of the original Telegram client for SailfishOS:
Fernschreiber by Sebastian J. Wolf and his collaborators: https://github.com/Wunderfitz/harbour-fernschreiber#contributions
and draws inspiration from some technical solutions of:
Yottagram by Michal Szczepaniak: https://github.com/Michal-Szczepaniak/Yottagram
Both projects served as a valuable starting point, but RooTelegram introduces a fully redesigned architecture, conceived to be faster, more stable, and better suited to modern devices.
Project goal
The goal of RooTelegram is to offer a Telegram client that is:
- responsive → instant startup thanks to the always-on daemon
- lightweight → minimal UI, no heavy effects
- reliable → notifications always working
- consistent with SailfishOS → native integration, respect for Silica guidelines
The design is intentionally bare and basic, because the priority is speed, not aesthetics.

[ITALIANO] RooTelegram — Un client Telegram leggero e reattivo per SailfishOS
RooTelegram è testato:
- Sony Xperia 10 III (SFOS 5.0)
- Jolla C2 (SFOS 5.1.0.8)
Questa applicazione è stata sviluppata utilizzando tecnologie di intelligenza artificiale, in particolare Warp Terminal e Claude Code Opus. Pertanto, se l'uso di un'applicazione generata tramite un modello linguistico su larga scala (LLM) non fosse per l'utente confortevole, si raccomanda di evitarne l'installazione e l'uso. Si specifica che qualsiasi commento negativo riguardante questa circostanza non verrà solo ignorato, ma comporterà il blocco immediato dell'utente.
Con la presente declino ogni responsabilità relativa all’applicazione, al suo funzionamento e a qualsiasi conseguenza derivante dal suo utilizzo. L’utente, scegliendo di utilizzare l’applicazione, riconosce e accetta di farlo a proprio ed esclusivo rischio, e concorda che lo sviluppatore non potrà essere ritenuto responsabile per eventuali danni, perdite o effetti negativi — diretti, indiretti, incidentali o consequenziali — derivanti dall’uso o dall’uso improprio dell’applicazione.
Caratteristiche principali
- Interfaccia semplice, veloce e ottimizzata per SailfishOS
- Supporto completo alla formattazione dei messaggi (grassetto, corsivo, monospazio, ecc.)
- Notifiche affidabili tramite daemon dedicato
- Supporto alle Custom Emoji
- Gestione dei PIN dei messaggi
- Supporto agli stickers
- Gestione delle richieste di accesso ai gruppi (per admin)
- Architettura moderna basata su UI + daemon, per apertura istantanea dell’app
Origini del progetto
RooTelegram nasce come evoluzione e modernizzazione del primordiale client Telegram per SailfishOS:
Fernschreiber di Sebastian J. Wolf e compagni d'opera: https://github.com/Wunderfitz/harbour-fernschreiber#contributions
e trae ispirazione da alcune soluzioni tecniche di:
Yottagram di Michal Szczepaniak: https://github.com/Michal-Szczepaniak/Yottagram
Entrambi i progetti hanno rappresentato un punto di partenza prezioso, ma RooTelegram introduce un’architettura completamente rinnovata, pensata per essere più veloce, più stabile e più adatta ai dispositivi moderni.
Obiettivo del progetto
L’obiettivo di RooTelegram è offrire un client Telegram:
- reattivo → apertura istantanea grazie al daemon sempre attivo
- leggero → UI minimale, nessun effetto pesante
- affidabile → notifiche sempre funzionanti
- coerente con SailfishOS → integrazione nativa, rispetto delle linee guida Silica
Il design è volutamente scarno e basilare, perché la priorità è la velocità, non l’estetica.

When deleting messages, the option is missing: delete only for me, delete for everyone

It was a great app, but the restyle made it unusable for me becsuse it became white text on a light background.
Also not sure that a style that gives the feeling of comic sans and wordart is what fits best on sailfish

Hey, I tested your 1.7 app! Interface is little bit diffrent, but not bad. Translation works partially, despite, you did not make any other translations than English version, what is interesting. My suggestion is to add some features in the future like commenting some posts, but i mentioned that before and i know it might be tough to implement. Especially both yotta and fern don't have that. The other thing i would like to mention is a synchronization with contacts. It does not work partially, same as in fern. I mean, when i try to find my friends, some of them are visible and some of them are not, despite i can see all of them on android telegram app. And what is interesting, when i can see them i don't see any profile picture. However, great app especially i know this is one of the first realease, so it is normal, not everything will work perfectly like in original android app. Keep going! I believe you can do it!

For "comment post" do you mean post in channel?
Kuba

Yes. Channels on telegram publish their posts and some of them are allowed to comment, the same like some of them are allowed to give a reaction by followers and some of them are not
