Organize yourselves for your classes, projects, or company with HiCal, the collaborative calendar! Create or join your class’ or club’s group, and get your shared timetable in your pocket. You can be part of multiple groups. You will receive Push notifications each time that a group’s event is modified, or an event is commented. Event repetition is supported (including “once every two weeks”). HiCal helps you to organize yourself and to collaborate with your friends and colleagues in different situations: - Students and pupils: Add comments to a lesson at a given day, to indicate homework and exams for example, and they will instantly be synced across smartphones and tablets, and shared with your class. You will not ever ask yourself again what is left to do: the answer will be in your pocket, up-to-date, at any moment. Even if only one person indicates the exams to come, everyone will be aware: one for all, and all for one! - Projects: Determine deadlines with your teammates, and discuss them in the comments! Your project is a secret? Then create a secret group, which will be hidden from the group search results. Only the people you add will be able to join the group. - Companies, clubs and organizations: Write down meetings’ or activities’ dates and locations, suggest or edit in real time, and instantly update all your fellows of a schedule change, thanks to push notifications. - Organize public events: Create a group, open to everyone, to let people stay tuned about your upcoming events! In this kind of group, only the group’s administrators can create or edit events. Thus, you can share your events, your live sessions for example if you’re a band, while keeping control. And if something unexpected happens, you can inform group’s members thanks to comments and push notifications! - Education: If you are an educational institution (school, college, university...), you can also use HiCal, by creating a group for each class or course, and inviting your students in them. Simplify your teachers’ and students’ life with HiCal! ## Key features - Group event scheduling - Real-time push notifications - Event comments and discussion - Shared timetables - Private and public groups - Event repetition support ## Recent user reviews (10 of 20) All indexed reviews: https://appshunter.io/ios/app/hical-collaborative-calendar/id913908607/reviews.md ### 5/5 — Facile et surtout gratuit *2025-05-03, version 2.0.15* Pour éviter de donner vos infos a Google ou autres aspirateurs de vie privée, cette application est simple, performante et fait ce qu'on lui demande. Merci aux devs ! ### 3/5 — Bien mais peut mieux faire *2023-08-11, version 2.0.13* Coorganiz ayant disparu je suis venu sur Hical avec mon équipe bon c’est pas mal mais il y a des choses à améliorer pour que ça soit plus clair et plus simple a gérer mais surtout ce qu’il me manque c’est une appli MacOs ou au moins pouvoir me connecter via mon navigateur ! ### 4/5 — Great, but crashes often *2022-01-31* great app, easy to navigate and great collaboration features; however, the app crashes every time i try to edit an event :( ### 2/5 — Bugs *2021-03-13, version 2.0.9* Très utile mais problème des synchronisation/serveur qui nous empeche de voir nos prochains événements depuis quelque jours, très gênant ### 5/5 — Why I love this calendar! *2021-01-24* I love this calendar! This is the only calendar app that allows me to collaborate with other people on a calendar. ### 5/5 — Five stars!!!!!! *2021-01-24* No other calendar has let me share my schedule with anyone else best calendar ever!!! ### 5/5 — Efficacité de la réponse suite bug *2021-01-13, version 2.0.9* Un bug nous empechait d’afficher une journée. En moins d’1/2 heure après avoir signalé le pb, il était résolu : bravo et merci ! ### 2/5 — Bien mais trop de bug *2020-03-12, version 2.0.5* Ce qui est chiant je suis administrateur pour ma classe tjr des problèmes de serveur et de synchronisation ### 4/5 — Application au top *2020-01-27, version 2.0.4* Cette application est vraiment performante et simple Des petites améliorations pourraient être amenées comme un lien à envoyer pour télécharger l’application et rejoindre les groupes créés. Et des pastilles de couleur sur les jours que l’on pourrait changer actuellement rouge mais avoir une petite palette 5/6 couleur serait parfait Rouge vert etc ... Merci en tout cas ### 4/5 — Presque parfaite *2020-01-14, version 2.0.4* Très simple d’utilisation et vraiment pratique. J’adore malgré quelques améliorations à apporter. Voilà ce que j’ai remarqué à l’attention du créateur : - les groupes une fois créés ne peuvent plus être modifiés au niveau de la couleur, du nom du groupe et on ne peut pas les supprimer. - les événements ne peuvent pas être interchangeables entre les groupes. Une fois le groupe validé, on ne peut plus les changer si l’on veut les adapter autrement. En bref, on ne peut pas le remanier en tant qu’administrateur et vu que L’appli est en phase de test et de découverte, je ne peux pas revenir en arrière. Sinon à mon avis c’est une appli qui est sur la bonne voie. ## Frequently asked questions about HiCal ### How does HiCal handle event updates?
