How to use

Pick a format

Choose binary, octal, decimal, or hex and your bit width.

Enter a value

Type or paste — results update instantly across representations.

Use the canvas

Tap bits to flip them and see the value change live.

Copy or export

One-tap copy, history, and batch convert when you need more.

Tips & tricks

Get more from the app.

Calculator

1. Set width before paste — Pasting `0xFFFF` into 16-bit mode behaves differently than 32-bit. 2. Endian toggle for protocol bugs — Flip BE/LE when a register looks “byte-swapped”. 3. Gray code — Use for encoder / rotary sensor homework or validation. 4. Float switch — Jump INT → F32 to decode IEEE 754 from the same bit pattern. 5. History export — Snapshot a debug session before clearing the chip

Bit canvas

6. Tap don't type — Mask tweaks (set bit 7) are faster on the grid than hex math. 7. Sign bit first — In signed 8-bit, bit 7 is your quick sanity check for negatives.

Copy workflow

8. Checkmark = shipped — Wait for the icon before switching apps. 9. Paste once — Verify hex has no stray spaces before `gcc` or `xxd`.

Converters

10. RAL colors — Firmware UI teams: match enclosure paint chips to RGB for docs. 11. Timestamp now — Tap current-time shortcut (if shown) for log correlation. 12. Comparator — Diff two hex constants side by side before merging branches.

Utilities (Premium)

13. CRC test vectors — Keep `123456789` and `Hello` strings as mental benchmarks. 14. Hex dump import — Paste a snippet from `xxd` to inspect structure. 15. QR for Wi-Fi or URL — Field provisioning without a laptop.

Widgets & layout

16. Three-tool board — Calculator tab + Widgets with Timestamp + Base64 covers 80% of bring-up. 17. iPad rail — Landscape uses side navigation—more vertical space for hex dump.

Settings

18. Dark theme default — Easier on eyes during late firmware sessions; light for outdoor. 19. Language per device — System language vs in-app override for bilingual teams. 20. Learn tab — Send interns to Settings → Learn before asking about two's complement.

Premium

21. One purchase — Restore on new phone before rebuying. 22. Future tools — Premium includes utilities we add later—no upsell tier. --- *Have a tip we should add? [email protected]*

Frequently asked questions

Quick answers about features, privacy, and billing.

What is Bit Scope?+

Bit Scope is a bit-level calculator and converter for developers. It converts between binary, octal, decimal, and hex; supports IEEE 754 floats; includes bitwise operations; and bundles converters and (with Premium) utilities like CRC and hash.

Is Bit Scope free?+

Yes. The calculator, bitwise tools, converters, history, and learning examples are free. Premium is a one-time purchase that removes ads and unlocks the Utilities tab.

Is Premium a subscription?+

No. Premium is a one-time in-app purchase. Future Premium-only tools are included without a recurring fee.

Which platforms are supported?+

iPhone and iPad (iOS). Android availability follows your Google Play listing. See store links on [zukiapps.com/bit-scope](https://zukiapps.com/bit-scope).

What languages are supported?+

12 base languages with regional variants (e.g. en-US, pt-BR, zh-Hans). Hebrew and Arabic include full RTL layout.

How do I open the bit canvas?+

On the Calculator tab, open the bit grid preview or modal (tap the grid / bit visualization control). Tap any bit to toggle it; values update across all representations.

What is MSB vs LSB bit order?+

MSB lists bits from most significant to least. LSB reverses the visual order. Choose the view that matches your datasheet or protocol diagram.

What endianness settings do?+

Big-endian stores the most significant byte first; little-endian stores the least significant byte first. Bit Scope shows how your integer maps to bytes for each mode.

Can I use custom bit widths?+

Yes. Select a preset (8, 16, 32, 64) or enter a custom width (within app limits) for masks and registers that are not power-of-two aligned.

How does copy work?+

Tap the copy icon on a result card or tool output. Text is copied without extra spaces (e.g. binary groups may be stripped per field). A checkmark confirms success.

Which tools are free vs Premium?+

Free: Base64, color picker, timestamp, value comparator, batch converter—and all calculator features. Premium: CRC, hash, ASCII/Unicode viewer, QR generator, hex dump—and adding utility tools to custom widgets.

Why does CRC say input is too large?+

Very large inputs can exceed safe calculation limits on device. Shorten the input or split the data block. Bit Scope shows a clear message instead of failing silently.
