This page collects the study tools HideawayVista offers for learners — high school and college students, and anyone studying on their own. Instead of installing an app for every small task, you can open this page and use a tool for a few minutes, then get back to work.

Everything here runs client-side, which means the calculations happen inside your own browser tab. That keeps the tools fast, free and private, and it means they work on locked-down school computers and slower phones as well as on a laptop. When your work is ready to hand in, the browser-based PDF compressor and other document tools further down this page take care of the file side.

This calculator uses a common 4.0 scale: A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D+ = 1.3, D = 1.0, F = 0. Schools weight honors, AP and pass/fail courses differently, so treat the result as an estimate and check your institution's grading policy.

Study Timer

A Pomodoro-style timer for focused study sessions. Pick a rhythm, press start, and study until the round ends — the timer switches between focus and break time for you.

Nothing is tracked — the timer lives in this tab

Focus

25:00

Ready when you are.

Completed focus sessions: 0

Flashcard Maker

Write a question or term on the front and the answer on the back. Click the card to flip it, shuffle the deck, and test yourself until the answers stick. Your deck is saved in this browser, so it will still be here the next time you open the page.

Quiz Maker

Turn your notes into a self-check quiz. Add questions and answers, then work through them one by one: reveal each answer and mark honestly whether you got it right. The quiz stays on this page until you leave.

Nothing is uploaded — the quiz exists only in this tab

Math Calculator

For quick checks while doing problem sets: type an expression and get the value. It handles arithmetic, percentages, powers and square roots — for example (48+52)/2, 15%*80, 2^10 or sqrt(144).

Evaluated in your browser
This is a numeric calculator, not an algebra solver: it evaluates the expression you type but does not rearrange equations or show working. Use % as "percent of", so 15%*80 means 15 percent of 80.

Unit Converter

Convert values between common units for length, mass and temperature — handy for science homework and for switching between metric and imperial.

Periodic Table

A compact interactive periodic table. Search by name or symbol, or click any element to see its atomic number, atomic mass and category.

How to use these tools together

Each tool is useful on its own, but they work best as a routine. Here is a simple study workflow you can borrow:

  1. Plan the session. Pick a timer preset and commit to one focused round before reaching for your phone.
  2. Turn notes into cards. Right after class, add the day's key terms and questions to the flashcard maker while the material is fresh.
  3. Quiz yourself. Enter the trickiest points into the quiz maker and answer honestly — the questions you miss show you what to review.
  4. Check the details. Use the math calculator and unit converter to verify values as you work through problem sets, and the periodic table when chemistry comes up.
  5. Watch the trend. When graded work comes back, add your real scores to the GPA calculator to see how the semester is trending.

A fair warning: tools support studying, they do not replace it. Short, regular sessions with your own notes and past papers will always beat hours of passive scrolling through study websites — including this one.

Document tools students also need

Frequently asked questions

Are these online study tools really free?
Yes. Every tool on this page is free to use, with no account, no email signup and no watermark or usage limit. Open the tool, use it, and come back whenever you need it.
Do I need to install anything to use these tools?
No. All of the tools run directly in your web browser on a laptop, tablet or phone. There is nothing to download and no app to install.
Is my data saved or shared?
Everything you type is processed in your own browser. Nothing is uploaded to a server. Flashcards you create are saved only in your browser's local storage, so they stay on your device.
How is a GPA calculated?
Each grade letter is worth a set number of points, for example A = 4.0 and B = 3.0 on a common 4.0 scale. Multiply each grade's points by that course's credits, add the results, then divide by the total credits. Because schools use different scales, always check your institution's grading policy.
What is the Pomodoro study method?
It is a focus routine where you study in short, timed blocks, classically 25 minutes, separated by 5-minute breaks. After a few rounds you take a longer break. The built-in study timer follows this pattern and lets you adjust the lengths.
Can online study tools help with exam preparation?
Yes, when you combine them. A common routine is to plan revision blocks with the study timer, turn your notes into flashcards, quiz yourself with the quiz maker, and track how your grades change with the GPA calculator. Tools support your studying; they work best alongside your own notes and materials.
