About

USM lock C

Features
Read full description

Dank der bis zu drei verfügbaren Nutzungsmodi lässt sich das Schloss C für unterschiedliche, sich wandelnde Bedürfnisse einsetzen. So können beispielsweise freie Schließfächer für eine temporäre Ablage von persönlichen Gegenständen genutzt, wiederum andere Schließfächer dauerhaft für eine langfristige Nutzung personalisiert werden. Bei einem personalisierten Schließfach hat der Benutzer zusätzlich die Möglichkeit, den Zugriff auf Schloss und Inhalt mit einer anderen Person oder Personengruppen via USM App zu teilen. Im Basisbetrieb, dem Public Locker Modus, gibt es keine feste Zuordnung zu einem bestimmten Schloss. Dadurch ist zur Organisation der Fächer kein klassischer Schließplan mehr nötig, was die Verwaltung der Schlösser um ein Vielfaches erleichtert. Bei Verlust der Schlüsselkarte kann der Admin unkompliziert eine Notöffnung vornehmen. Wie alle Systemteile von USM, lässt sich auch das Schloss C ganz im Sinne der Rückwärtskompatibilität an bereits bestehende USM Möbel montieren. Ohne großen Aufwand und ohne die gesamte Tür austauschen zu müssen, wird nur der bestehende Griff oder Schlossgriff durch das Schloss C ersetzt. Auch das Wechseln der Batterien ist mit wenigen Handgriffen von außen durchführbar. Dabei bleibt das Schloss verriegelt und die Inhalte sicher verwahrt.

Let the Wheel Decide

Read full description

Stop hesitating. Build your wheel, spin it: decided. Who does the dishes tonight? Pizza or sushi? Which movie? Who goes to the board? Who plays first? Some decisions don't deserve a ten-minute debate. Let the Wheel Decide settles them in five seconds, with a smile. YOUR WHEEL IN THIRTY SECONDS Type or paste your list: one line becomes one option, that's it. Paste your class's twenty names or the six restaurants nearby — the wheel is ready. Reorder with a drag, duplicate a wheel, share it as plain text. TRULY RANDOM DRAWS The result is drawn by iOS's cryptographic random generator before the wheel even starts spinning: the animation only reveals it. No bias, no tricks possible. The wheel itself spins like a real one — momentum from your flick, natural slowdown, a little tick on every segment, confetti at the finish. THREE DRAW MODES • With replacement: the drawn option stays on the wheel. The classic. • Without replacement: each draw removes its option until none are left. Perfect for handing out chores with no repeats. • Running order: the wheel chains draws and builds an ordered list by itself. Who goes first, second, third… then share the list in one tap. MADE FOR CLASSROOMS Teachers get it instantly: paste your student list, pick “running order”, and calling someone to the board becomes a little ritual instead of a dreaded moment. The draw is fair, visible to everyone, and nobody can blame anybody. GIVE YOUR CRAVINGS BETTER ODDS Any option can weigh two or three times more than the others: its slice grows, and so do its chances. Perfect for leaning gently toward pizza without slamming the door on salad. ALSO INSIDE • Five ready-made wheels, two of them open in the free version: Yes / No, Heads or tails, Numbers 1 to 10, Who goes first?, Tonight we eat… • History of each wheel's last fifty draws • Six matching color palettes • Interface in English and French, switchable inside the app YOUR DATA STAYS WITH YOU No account, no tracker, no third-party ads. Your wheels, options and draws are stored on your iPhone and never leave it. The privacy policy fits on one page, and you can read it offline inside the app. FREE, AND PREMIUM IF YOU WANT IT ALL The free version gives you two ready-to-spin wheels with the classic draw mode: “Tonight we eat…”, which you can edit three times, and “Heads or tails”. Premium unlocks everything: unlimited wheels, unlimited edits, all three draw modes, weighting, history and every palette. Three plans — weekly, monthly with a three-day free trial, or a one-time lifetime purchase. Prices are shown clearly before any payment, and subscriptions can be cancelled anytime in your App Store account settings. A question, a wheel idea we're missing? Write to us: contact@steverover.com — we read everything. Let the Wheel Decide. The wheel spins, you live.
