WhatsApp

Quick answer you can use now

Use what's (with an apostrophe) for "what is" or "what has." Use WhatsApp (capital W and internal capital A, no space) for the messaging app. Whats (no apostrophe) is almost always a typo in standard English.

• what's = what is / what has. Example: "What's your ETA?"
• WhatsApp = the app/brand. Example: "I'll send it on WhatsApp."
• whats (no apostrophe) = usually a typo; replace with what's or WhatsApp depending on meaning.

Core rules: contractions, apostrophes, capitalization

Decide meaning first: contraction or brand. If you mean "what is/has," write what's. If you mean the app, write WhatsApp. If neither fits, rephrase.

• Contractions: Apostrophes mark missing letters: what's = what + is/has.
• Possession: Don't use an apostrophe to make plurals (e.g., two phones, not phone's).
• Brand names: Preserve official capitalization: WhatsApp (no space, internal capital A).

Spacing and hyphenation

Many errors come from guessing word boundaries aloud. Check whether a term is closed (WhatsApp), hyphenated (well-known), or spaced (what ever → whatever is closed).

• Whats App (with a space) is incorrect for the app-keep it closed: WhatsApp.
• Compound adjectives sometimes use a hyphen (well-known feature), but not when the phrase is a single lexical item.
• When unsure, consult usage in published writing or revert to the phrase form: "what is" instead of a risky contraction.

Apostrophes and contractions (quick grammar)

Apostrophes show omissions or possession, not plurals. Contractions are fine in casual writing; spell out "what is" or "what has" in formal contexts.

• what's = what is / what has (contraction).
• its = possessive; it's = it is / it has.
• Avoid apostrophes for plurals: apples, not apple's.

How to fix your sentence (rewrite help)

Fixing a sentence takes three quick steps: identify the intended meaning, insert the standard form, then smooth the sentence for tone.

• Step 1: Ask whether you mean "what is/has" or the app. If neither, rewrite the idea.
• Step 2: Replace with what's or WhatsApp as appropriate.
• Step 3: Reread the full sentence and adjust punctuation or wording for natural flow.

Ready-made rewrites:

• Original: "This plan is whats workable if everyone stays late."
  Rewrite: "This plan is workable if everyone stays late."
• Original: "Can you send the doc to whats app?"
  Rewrite: "Can you send the doc to WhatsApp?"
• Original: "I wonder whats changed since yesterday."
  Rewrite: "I wonder what's changed since yesterday."

A simple memory trick

Picture meaning, not letters. If it answers "what is/has?" use what's. If it's a brand name, picture the app icon and type WhatsApp. If neither, rewrite the phrase.

• Associate what's with a short spoken question ("What is...?").
• Associate WhatsApp with the app logo and the internal capital A.
• Search your document for "whats" and decide case-by-case; fix all occurrences once identified.

Similar mistakes to watch for

Once one spacing or apostrophe error appears, related mistakes often follow. Scan for patterns and fix them together.

• Split words (e.g., "any more" vs "anymore").
• Incorrect capitalization of brand names (e.g., "instagram" vs "Instagram").
• Hyphen confusion in compounds (e.g., "long term" vs "long-term").
• Contraction omissions or incorrect apostrophes ("its" vs "it's").

FAQ

Is "whats app" correct?

No. The correct brand form is WhatsApp-no space, internal capital A.

When should I use "what's" instead of "whats"?

Use "what's" when it stands for "what is" or "what has." If you see "whats" without an apostrophe, change it to "what's" or write "what is" in formal writing.

Can I write "whatsapp" in lowercase in quick chats?

Casual chats may ignore capitalization, but the correct brand form is WhatsApp. Use that in professional or public writing.

Is "what's app" ever correct?

No. "What's app" would read as "what is app," which is not standard. Use "what's" only for the contraction and "WhatsApp" for the app.

How do I quickly fix multiple occurrences in a long document?

Search for "whats", "Whats App", and "whatsapp". For each hit decide: if it asks "what is/has" → replace with "what's" or "what is"; if it names the app → replace with "WhatsApp". Use find-and-replace carefully to avoid unintended changes.
