Right Angle is a calculator built for carpenters, builders, surveyors, machinists, and engineers — anyone who needs to solve a triangle, a trapezoid, or a circle without reaching for a notepad and the law of sines. Enter any valid combination of sides and angles and Right Angle solves the rest, including perimeter and area. The right triangle calculator is included for free; every other shape unlocks with a one-time Pro purchase or subscription. SHAPES • Right triangle (free) • Oblique triangle • Isosceles, right, and general trapezoids • Full circle — enter radius, diameter, or circumference • Segment of a circle ANGLE FORMATS • Decimal degrees • Radians • Degrees / minutes / seconds (DMS) • Percent grade • Pitch (x-over-12) LENGTH FORMATS • Decimal — the original, unitless entry. Best for metric. • Feet, inches & fractions — type values like 2' 5 1/2". • Inches & fractions — type values like 40 1/2". Pick a fraction precision from 1/2 down to 1/64 inch. Inputs and outputs both use the format you choose, and you can switch any time from Settings. DESIGNED FOR THE JOB SITE • A custom on-screen keyboard puts the symbols you need — feet, inches, fraction slash, degree, prime, double-prime — one tap away. • Helpful errors when an input combination can't be solved, instead of silent failures. • Available in English and Spanish — iOS picks the language to match your device. • Full VoiceOver support across the keyboard, input fields, shape diagrams, and results. Animations respect the Reduce Motion setting. EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy policy: http://rightangleapp.com/privacy.html

Your family’s week, clear at a glance. Milava is a childcare coordination app for the people already sharing care. Build the usual week around parents, a nanny or sitter, daycare or school. Then record what changes and see the current plan without piecing it back together from messages. SHARE CARE WITHOUT ANOTHER SUBSCRIPTION Caregiver access is free after an invite is accepted. One household subscription covers the family. BUILD THE USUAL WEEK Set the care that normally repeats. School belongs beside daycare, nanny care and sitter time—not hidden inside a generic event calendar. RECORD WHAT CHANGED Add a day off, a child’s activity or a trip. Say who does each pickup and dropoff, or ask someone to take one; they accept or decline, and Milava shows where each one stands. Leave a care note on the day. A caregiver can send a daily report after care, so the next handoff starts with the same context. SEE THE PLAN Open Milava to see who is caring for the kids now, who is next, and which days still need coverage. ASK ABOUT THE WEEK Ask Milava about your own schedule in plain words, or use plain words to start an entry you confirm before anything saves. AI features are optional. Free includes 20 questions or plain-words adds a month for the whole household; Premium removes that monthly limit. Questions about how to use Milava don’t count toward those 20. KEEP IT WHERE YOU LOOK Connect Google Calendar, and Milava keeps a calendar in your Google account up to date. Or subscribe from Apple Calendar or Outlook for free. That feed is read-only from Milava to your calendar app, and calendar apps choose when to refresh it. Once Milava’s events are in Google Calendar, ChatGPT or Claude can answer from them when the assistant has access to that calendar. That workflow sees schedule events—not care notes, medical details, emergency contacts, phone numbers, pay information or daily reports. TRIPS AND FLIGHTS Record a parent’s trip and add a flight. Live arrival times are free when flight data is available and refresh when the app opens. Premium adds background delay and landing alerts when notifications are enabled. Flight data comes from a third-party provider and may sometimes be unavailable or estimated. SIGN IN WITH A PASSKEY After adding a passkey on iPhone, sign in with Face ID instead of a password. MILAVA PREMIUM Premium adds asking trusted backups to help cover a gap, the morning briefing, tomorrow’s plan tonight, the week ahead, questions without the 20-a-month limit, and background flight alerts. Ask Milava answers about 7 days back and 30 ahead on Free; a year each way on Premium. Care by text (Premium): text Milava “Olivia is off Oct 12 to Oct 16” and it previews the change; reply CONFIRM to add it. Premium also includes a schedule photo turned into entries you confirm, and widgets for the Home and Lock Screen. BUILT CALM, ON PURPOSE No ads. No public feed. Milava is for the people your family already trusts—not a caregiver marketplace, payroll service or location tracker. SUBSCRIPTION DETAILS Milava Premium is an auto-renewing subscription.

Verdict
