"On iPhone?" reflects a genuine iOS release, not a pass-the-phone party app.
The list
1 Gnosia
The gold standard of solo social deduction
Gnosia is the game that proved single-player social deduction works. You are caught in repeating time-loops aboard a spaceship, rooting out the shape-shifting "Gnosia" who pick off the crew each night — classic Werewolf, except you argue, accuse, and vote against fourteen AI characters who each have their own personality and role every loop. It finally reached iPhone and iPad in 2026 as a premium app with no ads and no in-app purchases. If you want the definitive solo werewolf experience, start here.

2 Perdify
Best free pick on iPhone
Disclosure: we make Perdify. It is the deduction half of social deduction, built for one player — instead of voting out a werewolf with a group, you interrogate a cast of AI suspects (by text or out loud with your voice), catch the one who is lying, and accuse the killer. Alongside Gnosia, it is one of the only true play-against-AI solo deduction games on iPhone, and unlike Gnosia it is free to start.

Closest werewolf story to Gnosia
The closest narrative cousin to Gnosia: a horror visual novel set in a mist-trapped village whose deadly ritual is a literal Werewolf game, with a time-loop you use across deaths to unmask the hidden "wolves." The writing is superb — around 95% positive on Steam. Caveat for iPhone players: it currently lives on iOS only inside Crunchyroll’s Game Vault, so you need a Crunchyroll subscription rather than a one-time purchase.

4 Danganronpa: Trigger Happy Havoc
Best deduction-adjacent mystery on iPhone
Fifteen students are trapped and forced into a kill-or-be-killed game, and every murder triggers a "Class Trial" where you debate the evidence and vote for the culprit. It is deduction-adjacent rather than systemic — the killer is authored, not randomized each run — but the "expose the liar in a trial" fantasy is pure Gnosia energy, and it is a polished premium app on iPhone (with two sequels also on iOS).

5 Demon Bluff
The pure-deduction one to watch
The breakout pure-deduction title: a single-player roguelike where demons have infiltrated a village disguised as allies, and you flip character cards and reason out who is lying — think Blood on the Clocktower without needing a group. Its demo is "Very Positive" on Steam. The catch: it is PC-only and not fully released yet (expected later in 2026), so for now it is the one to watch rather than play on your phone.

On PC, console, or multiplayer only
A few more solo picks live on PC and console, and some genre icons are worth knowing about —
if only so you are not caught out assuming they are solo or on iPhone.
- Lost Dimension A single-player tactical RPG where one of your squad is a hidden traitor you must deduce and eliminate — often cited as a Gnosia inspiration. PC and PlayStation only, not on mobile.
- Black Closet A single-player "find the mole" management game about running a student council’s dirty work. PC, Mac, and Linux only.
- Zero Escape / 999 Beloved betrayal-and-escape visual novels with hidden-identity tension — but the old iOS version was delisted, so they are PC and console only now. Do not assume they are on iPhone.
- Among Us & One Night Ultimate Werewolf The genre’s icons, but multiplayer only. Among Us has no vs-bots mode (its solo "Freeplay" is just task practice), and the One Night app is a narrator tool that needs the physical game and a group.
FAQ
Are there any single-player social deduction games?
Yes, but they are rare — social deduction is usually a multiplayer party genre. The standout solo game is Gnosia, where you play Werewolf against AI characters. Others worth your time include Raging Loop, Danganronpa, the upcoming Demon Bluff, and Perdify, which turns the "spot the liar" loop into solo interrogation of AI suspects.
Is Gnosia on iPhone?
Yes. Gnosia came to iOS in 2026 and is a premium app (about $24.99) with no ads and no in-app purchases, playable on iPhone, iPad, and Mac. It was previously on Switch, PC, PlayStation, and Xbox.
What are the best games like Gnosia on iOS?
On iPhone specifically, the closest picks are Perdify (free — you interrogate AI suspects to find the liar), Danganronpa (paid class-trial murder mysteries), and Raging Loop (a werewolf visual novel, available on iOS through Crunchyroll). Demon Bluff is the closest pure-deduction game in spirit, but it is PC-only for now.
Can you play Among Us single-player or against bots?
No. As of 2026, Among Us is multiplayer only — there is no campaign and no vs-bots mode. Its offline "Freeplay" is just a practice space to learn the maps and tasks, with no other players and no deduction round.
Is there a free single-player social deduction game?
Yes — Perdify is free on iPhone and plays like solo social deduction: one suspect is the lying killer hiding among the cast, and you interrogate everyone to expose them. Most others, including Gnosia and Danganronpa, are paid.
Is Perdify really a social deduction game?
It is the deduction half, rebuilt for one player. Instead of voting out a werewolf with a group of humans, you interrogate a cast of AI suspects on your own, catch the one whose story does not hold up, and accuse the killer. Same "find the liar among the group" core — designed to be played solo.
