Vous connaissez ce son. Les bips qui s'accélèrent, les témoins qui passent au rouge, et le vortex qui s'ouvre à la dernière seconde. Sliders Timer met ce minuteur dans votre poche. Réglez le compte à rebours. Appuyez sur END. Regardez l'objet s'animer comme vous l'avez vu faire à l'écran. CE N'EST PAS UN DESSIN Les animations ne sont pas approximées : elles viennent du programme d'une réplique physique construite autour d'un Arduino, et elles sont rejouées image par image, avec leurs fréquences et leurs durées d'origine. Les quatre témoins latéraux clignotent à quatre cadences différentes, comme sur l'objet. C'est ce décalage, et pas un effet aléatoire, qui lui donne son rythme. Les bips du décompte passent par cinq régimes de plus en plus pressants. L'arc rouge respire d'autant plus vite que le temps s'épuise. LE SAUT, ET CE QUI PEUT MAL TOURNER Lancez un décompte jusqu'à 999 jours, ou forcez le saut quand bon vous semble. Mais vous pouvez aussi déclencher le burnout : quatre-vingt-dix secondes de sursis, et pas une de plus. Les paliers sonores s'enchaînent, les témoins se figent l'un après l'autre. À la toute dernière seconde, un appui bien placé vous sort d'affaire. Sinon le vortex s'ouvre pour de bon, et le minuteur meurt. CE QU'IL Y A DEDANS • Un compte à rebours réglable à la seconde, jusqu'à 999 jours • Le saut, le saut anticipé et le mode burnout • La séquence d'allumage complète, écran par écran • Une molette qui se tourne au doigt • Une notification quand le décompte atteint zéro, même application fermée • Une notice intégrée, parce que PWR, FCN et END ne parlent pas d'eux-mêmes SANS RIEN D'AUTRE Aucune publicité, aucun achat, aucun compte, aucune donnée collectée. Tout fonctionne hors ligne. HOMMAGE DE FAN Ce projet est un hommage sans affiliation ni licence officielle. Sliders est une marque de ses ayants droit. Aucun lien avec les producteurs ou les diffuseurs de la série.

Castmates is a private, on-device AI app for interactive character stories, running entirely on your iPhone. Most AI apps send every word you type to the cloud and make you sign in. Castmates doesn't: the model lives on your device, so your conversations are never sent to a server, there's no account, and it even works offline. Meet a cast of 35 characters who actually stay in role. They don't reply like a chatbot: they narrate the scene, act, and remember what happened last time, so the story keeps building each time you come back. A CAST FOR EVERY MOOD Meet 35 hand-crafted characters across 8 genres: • Friends & Mentors: a loyal best friend, a warm life coach, a hype-man trainer • Romance: slow-burn crushes and devoted partners • Fantasy: elven rangers, dark knights, fae sorceresses, gentle orcs • Sci-Fi: sardonic ship AIs, starship captains, curious aliens • Anime: tsundere rivals, shy schoolmates, bubbly childhood friends • Historical: Regency nobles, samurai, Renaissance inventors, jazz-age icons • Mystery & Horror: noir detectives, vampire countesses, eerie keepers • Adventure: pirates, treasure hunters, wasteland survivors DROP INTO A SCENE Every character comes with ready-made scenarios, 127 in all, so you can jump straight into a story, or set your own opening scene and tone. BUILD YOUR OWN Create custom characters end to end: name, persona, greeting, appearance, tone, and a signature opening scene. Set their avatar from your photo library. They'll act exactly the way you wrote them. PRIVATE BY DESIGN: ON-DEVICE AI The whole AI runs locally on your iPhone. After a one-time model download: • Your conversations are generated and stored on-device: never sent to a server • No account, no sign-up, no profile • Nothing is logged on our servers or used to train models • It keeps working in airplane mode: on a flight, on the subway, off the grid THEY REMEMBER YOU Castmates summarizes past sessions, so characters recall who you are and pick up the thread days or weeks later. FREE TO START Start free with the full cast. Upgrade to Castmates Pro for unlimited messages and unlimited custom characters, and like everything else, they stay private on your device. Castmates Pro options: • Monthly subscription • Annual subscription (best value) • Lifetime purchase (one-time, not a subscription) Payment is charged to your Apple ID at confirmation of purchase. Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period; the Lifetime option is a one-time purchase that does not renew. Manage or cancel anytime in your App Store account settings. Privacy Policy: https://get-castmates.com/privacy Terms of Use (EULA): https://get-castmates.com/terms
