Med-math practice for nursing students — a calm, ultra-legible dosage drill tool for study sessions and exam prep. A study tool only: never for patient care. FREE TRIAL: try the yearly plan free for 3 days. After the trial it renews at the yearly price unless cancelled at least 24 hours before the trial ends. Manage or cancel anytime in your Apple ID settings. Practice the classic weight-based problems with generic numbers: enter body weight (kg or lb) and a dose factor in mg/kg, double-check your entries on a confirmation card, then read the answer on a huge result display. BUILD THE SAFETY HABIT — FREE • Weight-based dose: weight × mg/kg, with kg ↔ lb entry • Max-dose guard: add an optional practice limit (mg/kg or total mg) — answers show green under 90%, a near-limit warning at 90–100% and a clear over-limit flag beyond • Volume problems: dose ÷ concentration (mg/mL) → mL to draw • Per-dose from a daily total: split across 1–4 doses per day • A double-check step before every result — the habit exams reward • Share answers as plain text PRO • Quick converters: mcg ↔ mg ↔ g and kg ↔ lb, live in both directions • Save practice problems to history and review them before the exam • Export clean PDF practice sheets to file or print Designed for long study nights: big keypad, huge numerals, Aurora dark and Bright light themes. Everything stays on your phone — fully offline, no account, no tracking. This app offers generic numeric practice only. It contains no drug names, no drug database and no dosing recommendations, and it must never be used for actual patient care. ——— Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://hdappstudio.com/dosagecalc/privacy/

About

Loopy Letters

Watch a pen movement, trace the model, then try writing independently. Loopy Letters brings US and UK handwriting practice together on iPhone and iPad, and includes French cursive too. By default the app follows the device language. Choose the handwriting your child learns in onboarding or Settings: • US: Traditional, Slanted and Vertical, each with print and cursive, on primary paper with a dashed midline. • UK: Print, Selected joins and Joined, with alternative f, q and t forms, British-English words and speech, and four-line guides. These models follow handwriting conventions used in England; school schemes vary. • French: the joined cursive taught in French schools, on Seyès ruling, with French words and speech. In this collection the app is in French and is called Plumélio. Practice lowercase and capital letters, numbers, letter pairs, words, warm-up shapes, your child’s name and your own text. The animation demonstrates each model’s movements and joining rules. Stars compare the attempt with that model; they are a guide, not a school grade. Follow your child’s teacher and practice on paper too. Switch handwriting whenever you need to. The app remembers your style in each one, and each keeps its own stars, notebook and stickers. The notebook saves the best writing attempts. Adjust the paper size, left-handed layout, Pencil-only input, sounds, spoken guidance and stickers. Free in every handwriting: warm-ups, numbers, selected lowercase letters, capitals A and M, the first row of letter pairs or syllables and a sample word (“mom”, “mum” or “ami”). One optional purchase, Everything, unlocks all remaining exercises in all three, the child’s name and custom text. No subscription; Family Sharing supported. Practice works offline. No accounts, ads or analytics. The name, texts and writing stay on the device and may be included in device backups. External links and purchases are behind a parental gate. Requires iOS or iPadOS 17 or later. Write with a finger, or Apple Pencil on a compatible iPad. Published by druidori s.r.o.; not affiliated with any handwriting program publisher.
