Short answer: A WhatsApp last seen tracker is only as honest as the data it can legally see. The good ones log the public "last seen / online" presence that WhatsApp already shows you and graph it over time. None of them can read messages, see hidden last seen, or bypass privacy settings — and any app that claims otherwise is the scam you should walk away from.
Search "whatsapp last seen tracker" and you get two kinds of results: a handful of small presence-logging apps that do one narrow thing, and a wall of listings that promise to "spy on anyone's chats" or "see who they talk to." The second kind is where the money — and the danger — lives. So this is a scored comparison of the apps people actually type into the store search bar, plus a five-point test you can run on any of them before you pay.
One thing to settle first. A presence tracker is not surveillance software. WhatsApp exposes a "last seen" timestamp and an "online" indicator to people allowed to see them, per the WhatsApp Help Center page "About last seen and online." A tracker just records that public signal at intervals and shows you the pattern. It sees exactly what you'd see by opening the chat yourself — nothing more.
What a last seen tracker can and can't touch
The dividing line is privacy settings, and they are stricter than most listing copy admits. In WhatsApp, last seen visibility is set to Everybody, My Contacts, My Contacts except…, or Nobody (WhatsApp Help Center, "How to change your privacy settings"). If someone picks Nobody, their last seen is gone — for you, for any app, for everyone. There is no setting a third-party tracker can flip to bring it back.
WhatsApp also enforces a reciprocal rule the marketing pages never mention: if you hide your last seen, you lose the ability to see others' last seen (WhatsApp Help Center). So a tracker that wants to log presence needs your own last seen left visible. That is a real tradeoff, not a footnote.
Telegram works similarly. Its options are Everybody, My Contacts, and Nobody, the sharing is reciprocal, and "last seen recently" is a deliberately vague band — anywhere from seconds to a few days — designed so exact times can be hidden (Telegram FAQ). A tracker can record the labels Telegram shows. It cannot resolve "recently" into a precise timestamp the platform is hiding on purpose.
Claim: No legitimate tracker can show a contact's last seen if that contact set last seen to "Nobody."
Evidence: WhatsApp Help Center, "About last seen and online" — the Nobody setting removes the timestamp at the platform level.
Limit: This does not stop scam apps from claiming they can; it stops them from actually doing it.
Action: Treat any "see hidden last seen" promise as a lie and a payment trap.
The apps people actually search for, scored
Below are the names that surface most often for this query — WaStat, WaLog (also listed as Whatslog), WaRadar, Walastseen — alongside Suna. I scored them on the dimensions that decide whether an app is safe and useful, not on feature-list length. I did not invent download counts, accuracy percentages, or revenue figures; where I couldn't verify a hard number, the cell says what the app's own listing claims and nothing more. Store details change, so re-check the listing on the day you buy.
| App | Free tier | How it gets presence | Login required? | Where data lives (per listing) | Editorial note |
|---|---|---|---|---|---|
| Suna (Seen) | Yes — track one number free | Polls the public last seen / online that WhatsApp & Telegram already expose | No WhatsApp login; you enter a phone number | States its data handling in-app; no chat access requested | Narrow by design — presence timeline only, no message claims |
| WaStat | Limited trial, then subscription | Polls public online status | Phone-number based | Per its store listing | Popular; verify the trial-to-paid terms before tapping subscribe |
| WaLog / Whatslog | Limited free, paywalled reports | Public online-status polling | Phone-number based | Per its store listing | Two listing names appear; confirm which developer you're installing |
| WaRadar | Trial, then subscription | Public online-status polling | Phone-number based | Per its store listing | Read recent reviews for billing complaints before paying |
| Walastseen | Varies by listing | Public online-status polling | Phone-number based | Per its store listing | Generic name used by several clones; check the developer field carefully |
The pattern across the honest ones is identical: they all poll the same public presence signal, none ask you to log in to WhatsApp itself, and the real differences are pricing, billing transparency, and how the developer talks about limits. The apps that don't fit this pattern — the "read their messages" and "see deleted texts" listings — aren't competing on these dimensions because they can't deliver any of it.
The 5-point scam test (and Suna's own scorecard)
Run this on any tracker before you pay. It is the same checklist I'd use on Suna, so here is Suna graded against it in public.
- Does it promise message access? Reading chats is impossible for a third-party app — WhatsApp messages are end-to-end encrypted. Any "see their messages" claim fails instantly. Suna: pass — it makes no message claim.
- Does it claim to defeat "Nobody" / hidden last seen? The platform removes that data; no app restores it. Suna: pass — it only logs presence that's already visible.
- Is the price and renewal shown before checkout? "Free trial" dark patterns — auto-renewing subscriptions buried behind a free hook — are exactly what the U.S. Federal Trade Commission warns about in its guidance on negative-option and subscription marketing. Suna: pass — free single-number tier, paid tiers stated up front.
- Does it ask you to log into WhatsApp or install a modified client? Modded apps like GB WhatsApp and WhatsApp Plus violate the WhatsApp Terms of Service and can get the account permanently banned. A tracker that needs your WhatsApp credentials is a red flag. Suna: pass — no login, no mod.
- Is the developer identifiable? A real company name, a working site, and a portfolio beat an anonymous listing. Suna: pass — built by Activity Monitor, the studio behind it.
If an app fails point 1 or 2, stop. It is selling a capability that does not exist, and what you're actually buying is a subscription wrapped around a false promise.
What "free" really means here
Almost every tracker in this category leads with a free entry point and charges for scale — more numbers, longer history, exportable reports. That is a normal model. The problem is the apps that use "free" as bait for a near-instant auto-renew. The FTC's stance on negative-option marketing is straightforward: the price, the recurring charge, and how to cancel should be clear before you commit, not discovered on next month's statement. Before subscribing to any of these, open the store listing's subscription terms and read the renewal line. How Suna tracks last seen is built around the free single-number tier precisely so you can confirm it does what you need before any payment.
FAQ
Can any app see a WhatsApp contact's last seen if they hid it?
No. If a contact set last seen to Nobody, WhatsApp stops exposing the timestamp at the platform level, so there is nothing for any third-party app to read (WhatsApp Help Center, "About last seen and online"). Apps that claim to reveal hidden last seen are misrepresenting what's technically possible.
Will using a last seen tracker get my WhatsApp account banned?
A tracker that only polls public presence and does not require your WhatsApp login or a modified client is not installing anything inside your account. The ban risk comes from modified clients like GB WhatsApp or WhatsApp Plus, which violate the WhatsApp Terms of Service. Avoid any tracker that asks you to log in to WhatsApp through it.
Is tracking someone's last seen legal?
It depends on who you track and where you live. Logging your own account, or a family member's with their consent, is generally fine; covertly monitoring another adult can run into privacy, stalking, or wiretapping rules, which vary by jurisdiction. This is general information, not legal advice — check your local law and get consent before tracking anyone but yourself.
Does Telegram tracking work the same way?
Roughly. Telegram offers Everybody, My Contacts, and Nobody, the sharing is reciprocal, and "last seen recently" is intentionally vague (Telegram FAQ). A tracker can log the labels Telegram displays but cannot convert a deliberately fuzzy status into an exact time.
How I'd choose
Start with the five-point test, not the feature list. Throw out anything that promises message access or claims to beat hidden last seen — those two failures tell you the rest of the listing is fiction. Among the honest apps that survive, the real decision is billing transparency and a free tier you can actually try first. Track only your own account or a family member who has agreed, keep the data off shared photo rolls, and treat the timeline as presence, not proof of anything more. Suna is made by Activity Monitor, the same studio behind the family-presence app Luna — both built around the narrow, consent-first idea that you should be able to see what a platform already shows you, and nothing it doesn't.
