Senior assassin apps, compared

How to read that table

Four of those columns are easy to get wrong, so here is exactly what we mean by them.

• Cost is what the organiser and players can be charged, including subscriptions and in-app purchases, not just the install price. Every app here installs for free. That is not the same as being free.
• Tracks location means the product collects a device position for gameplay, on its own published account. We take that from the store privacy labels, which are the developer's own declarations, plus whatever the product says on its site. We do not test apps to confirm it.
• Prize pot handling means whether the tool itself collects entry money or holds a pot. Where it says not published, that means the product does not describe doing so anywhere we could find. It does not mean the class is not passing an envelope around. Most of the objections schools raise about this game are about pooled entry fees, and no app in this category removes them.
• Not published always means we looked and the product does not say. We would rather leave a gap in this table than fill it with a plausible guess, because a stale price stated confidently is worse than no price at all.

Splashin

Splashin is the category, in practice. Its Google Play listing showed 100,000+ installs and a 4.7 average from 25,400 ratings on 2026-08-21, its last Android update was 2026-07-27 and its last iOS release was 2026-08-07. Wikipedia's article on senior assassin names Splashin and no other app. If you are trying to get 200 classmates onto one platform, name recognition is worth more than any feature list, and only Splashin has it. Players sign up: its Google Play description opens with "Sign up for a game with your friends," and its App Store privacy label lists name and email collected for app functionality.

The thing our earlier version of this page got wrong is that Splashin has done more safety work than any other product here. It ships drive detection that "will automatically stop users when they may be in a moving vehicle." It has Personal Safe Zones that hide a player from the map. School or student admins can disable the map entirely for school hours, dances or overnight, remove players, mute chat, mark players safe and approve who joins. Every player must agree to community guidelines covering recognisable toy guns and respect for private property before playing. Given that the documented harms on our safety page are cars, mistaken-for-real guns and trespassing, that is a serious answer to all three, and we were wrong to imply Parabellum was alone on the driving problem.

What you are trading for it is location. Wikipedia describes Splashin as broadcasting participating players' locations as an added challenge, the App Store privacy label lists Precise Location linked to your identity, and the listing warns the app may use location when it is not open. Splashin's own safety page argues this is safer than the alternative, on the grounds that classes otherwise share Life360 with everybody, and that argument is not silly. It is still a live map of where teenagers are, sitting on a company's server for a season.

One fact deserves to be read carefully rather than shouted about. Splashin's own Google Play data-safety declaration currently states "Data isn't encrypted — your data isn't transferred over a secure connection," alongside a list of collected data that includes approximate and precise location, name, email, in-app messages, and photos and videos. That is the developer's own submission to Google, not a test result and not an accusation, and developers do sometimes fill these forms in wrong. But it is published, it is dated, and if you are the teacher signing off on this for a class, it is the line to ask about.

Catcher Games

Catcher Games is the most conventional product in the category and the easiest to explain to a parent: the host works from a web dashboard, invites players by email, and the app handles target assignment, elimination confirmation, a live scoreboard, a game log and push notifications. Games of up to ten players are free and unlimited. Beyond that the host pays $1.50 once per player, and only for players who actually accept the invite, so you never pre-pay for a roster that does not show up. The site advertises support for up to 500 players per game. Its FAQ is unusually direct about the money: hosts "typically collect separate fees from players for cash prizes," which the platform does not touch.

There is one thing about Catcher Games you should know before you send the link to your class, and it is not on their site. As of 2026-08-21, every "Download Senior Assassin App" button on catchergames.com, on the home page and the features page alike, points to a link that resolves to SLAP: Hide, Seek, Record, published by Integrated Reality Labs, Inc. The home page even says "Download the SLAP app" in the middle of a page otherwise branded Catcher Games. We do not know the commercial arrangement behind that and we are not going to speculate. What we can tell you is that the app your players install is SLAP, published by a different company, with SLAP's privacy labels and SLAP's subscription, and that the Catcher Games site says nothing about location tracking while SLAP's own listing describes a live map. Read the SLAP section before you decide.

HuntinHuntin

HuntinHuntin is the reason this page needs a verification date on it. Through 2025 it was widely recommended as the free, no-ads, no-paywall option, and our own strategy notes described it that way. That description is now out of date. The current App Store listing for Senior Assassin - HuntinHuntin by Zinance Inc. sells a Weekly Premium at $4.99 and a Monthly Premium at $12.99, and states plainly: "Free to play. Premium unlocks real-time tracking." The hxh.app home page leads with "GPS tracking, photo proof eliminations, and power-ups that spawn at real locations."

Taken on its own terms it is a capable product. Photo-proof eliminations are genuinely useful, because arguments over whether a tag counted kill more games than anything else. Chat and push notifications are built in, and it has three elimination types including a proximity auto-tag. It was updated on 2026-08-12, so somebody is working on it.

Two things about the listing are worth flagging. The privacy label lists Health & Fitness data linked to your identity alongside Location, which is unusual for a game of this kind and is not explained anywhere on the site. And the App Store age rating is 4+, the lowest band Apple offers, on an app whose headline feature is live location tracking. We are not saying the rating is wrong. App age ratings are assigned against Apple's content questionnaire, and location tracking is not a content category. We are saying that if you assumed a 4+ rating implied something about how the app handles children's location, it does not.

The other practical point: we could not find a Google Play listing. The hxh.app site displays a "Download for Android" button, but on 2026-08-21 that button carried no link and a Google Play search for the name returned nothing. Treat HuntinHuntin as iOS-only until that changes, which in a class where half the phones are Android is decisive on its own.

Parabellum

Parabellum is the most thoughtfully designed product here and the least used. It is free to download and its listing says the features are "free to use with no subscription costs or player limits" — geo-fencing to define play areas and safe zones, schedules that turn the game off during school hours or special events, purges, host-granted immunity and revives, team or solo play, and invitation-only games.

Its standout feature remains speed limits, which "disable elimination abilities while players are in moving vehicles, to discourage playing while driving." Every death connected to this game has involved a car, so building the rule into the software rather than the honour system is the right instinct, and we will keep saying so about a competitor. Splashin's drive detection now does the same job. Parabellum was not the only one, but it was the one that made it a headline feature.

Be honest with yourself about the trade. Parabellum's last iOS release was 2025-01-28 and its last Android release was 2025-01-21, which is around nineteen months of no updates as of this writing. Google Play showed 1,000+ installs and six ratings. And its two store listings disagree with each other about privacy: the App Store label lists Location, user content and identifiers as linked to your identity, while the Google Play data-safety section says "No data collected" and "Data is encrypted in transit." Both are the developer's own declarations. We cannot tell you which is accurate, only that they cannot both be.

SLAP

SLAP is worth its own entry because it is what Catcher Games now installs. It is a broader social game — hide and seek, manhunt, tag, and senior assassin among them — built around auto-recorded video: you record the tag, it scores instantly, and the clip goes into an in-game feed. It has a live game map, safe zones, ghost roles that keep eliminated players involved, and a Stealth Mode sold as a $2.99 power-up that hides your location from your hunter. Pro is $3.99 weekly or $9.99 to $12.99 monthly. It is the most actively developed app in this comparison, last updated 2026-08-15, with 10,000+ Google Play installs.

It is also the most data-hungry. Its App Store privacy label is the only one here with a "Data Used to Track You" section, declaring usage data used to track you across apps and websites owned by other companies. Location, contact info, user content, identifiers, usage data and diagnostics are all linked to your identity, and location may be used when the app is closed. If the class is choosing Catcher Games because it sounded like the low-key option that never mentioned GPS, this is the app they will actually be running.

Running it with no app, which is what we build

This site is not an app. It is a set of web pages: an editable rulebook you publish under a class code, a target generator, and a live board students open in whatever browser is already on their phone. Nobody downloads anything and nobody makes an account. There is now also an invite-only Android beta, which is the same website in a full-screen shell and collects nothing extra. It is not on Google Play.

Four things follow from that, and they are the only reasons to choose it.

• No location data exists. Not stored, not shared, not collectible. There is nothing to broadcast or leak because it is never gathered.
• We cannot read your game. The class code never reaches our server. Rulebook, roster, targets and eliminations are encrypted in the organiser's own browser and stored as ciphertext under a one-way hash, so a roster of real student names is not sitting in a database we can open. The full detail is here.
• Free with no pot. No entry fee and no jackpot, by rule rather than by pricing tier. Pooled entry fees are the part of this game schools object to most, and the rulebook is written to remove them.
• Nothing to install. The hardest part of organising this game is getting a hundred people onto the same platform. A link that opens in a browser skips that step for everyone, including the students whose parents will not approve an install.

What the other options do better than us

If a comparison page written by a competitor concludes that the competitor wins everything, it is worth nothing. Here is where we lose.

• Push notifications. A web page cannot tap someone on the shoulder. Students check the board; the board does not chase them. Splashin, Catcher, HuntinHuntin, Parabellum and SLAP all push. If your class needs pinging to stay engaged, use a native app and do not use us.
• Every GPS feature. No geo-fencing, no proximity alerts, no safe-zone enforcement, and no speed limits. Parabellum's speed limits and Splashin's drive detection are the two best safety features anyone in this category has shipped, and we structurally cannot offer either. We answer the driving problem with a rule on the safety page, which is weaker than software that enforces it.
• Photo and video proof. HuntinHuntin verifies eliminations with a photo and SLAP auto-records them. We deliberately never touch student photos, which means disputes come down to your rulebook and a group chat.
• Scale and trust signals. Splashin has 100,000+ installs and 25,400 ratings. We have no store listing, no install count, no ratings and no reviews. A student proposing this to a class has nothing to point at except the site itself.
• Brand recognition. Splashin is the name your class already knows and the one Wikipedia names. We are a website nobody has heard of.
• Organiser rights live on one device. Your edit key sits in your browser's local storage. There is a backup download, but lose the device without taking it and you lose control of the game. That is the direct, unavoidable cost of having no accounts.
• We show ads. The site runs Google AdSense to stay free. Catcher Games does not run ads. Splashin's and Parabellum's Google Play listings both carry a "Contains ads" badge, so on this one we are in the majority, but "free" here means ad-funded, not costless.

What changed since the 2025 season

This category moves fast enough that a year-old recommendation is usually wrong. Verified 2026-08-21:

• HuntinHuntin is no longer the free, no-paywall option. It now sells a $4.99 weekly and $12.99 monthly premium, and leads its marketing with GPS tracking.
• Catcher Games no longer ships its own player app. Its download buttons install SLAP, published by Integrated Reality Labs.
• The "$1.50 per player" figure belongs to Catcher Games only. It is still current for Catcher. It has nothing to do with Splashin, whose charges are in-app purchases running to $25.99 on the App Store and $49.99 per item on Google Play.
• Splashin shipped drive detection and personal safe zones. Any comparison that gives Parabellum sole credit for vehicle safety, including our own earlier version of this page, is out of date.
• Parabellum has not shipped a release since January 2025 on either platform.

How to actually choose

1. Would a parent or an administrator object to live location tracking? If yes, that decides it before anything else. Five of the six options here collect position. Ask the question out loud rather than finding out in a meeting.
2. Will everyone actually install an app? If getting the class onto one platform is the hard part, or if half the phones are Android and your shortlist is iOS-only, a link that opens in a browser removes the problem.
3. Is anyone willing to pay, and who? Catcher's $1.50 per player is one student's credit card unless they collect it back. Subscriptions land on individual players instead, which is harder to see coming.
4. Do you need push notifications? If yes, you need a native app. This is the clearest single reason not to use us.
5. Does your class have a car problem? Then either pick a tool with drive detection or speed limits, or write the rule and enforce it. Read the safety page first whatever you pick — no app fixes this, and the safety agreement is the part that does the work.
6. Write the rules before you pick the software. Every tool here assumes you already know your safe zones, your elimination standard, your deadlines and your dispute process. Ours are free to copy even if you run your game somewhere else.
