We ran 400+ hours of testing across PUBG Mobile, Genshin Impact, and Call of Duty Mobile to find the tools that actually improve performance — not just add placebo features.

Free (Pro: $2.99/mo)
The most comprehensive Android gaming optimiser. Clears RAM, boosts CPU priority, blocks notifications, and disables background processes — all in one tap before launching any game.
Pros
Cons
Our Verdict
The most polished free option on Android. On mid-range phones (Snapdragon 7xx series), RAM clearing and background process suspension genuinely improves frame consistency. On flagships, the FPS overlay and notification blocker are the standout features.
Free (Pro: $1.99)
Real-time FPS, CPU, GPU, RAM, and temperature overlay for any game. Essential for diagnosing whether performance issues are CPU, GPU, or thermal throttling — no root required.
Pros
Cons
Our Verdict
An essential diagnostic tool. If you're experiencing lag, this tells you whether it's a CPU spike, thermal throttle, or just network — crucial for knowing which tool to use next. The free version is sufficient for most users.
From $6.67/month
Not all VPNs are good for gaming — most add latency. ExpressVPN's Lightway protocol and gaming server routing consistently delivers the lowest added latency of any VPN we tested for mobile gaming.
Pros
Cons
Our Verdict
If you're gaming on servers in another region or your ISP routes traffic poorly, a VPN can actually reduce ping. ExpressVPN's Lightway protocol adds the least overhead. Full VPN comparison is on our gaming VPNs page.
Free
The best gaming performance tool for iPhone. Reduces background app refresh, enables sustained performance mode, and provides a minimal HUD. No jailbreak required.
Pros
Cons
Our Verdict
iOS is more restricted than Android for performance tools, but Gamehance extracts what it can within Apple's sandbox. The sustained performance mode toggle is the most useful feature for long gaming sessions where thermal throttling kicks in.
Free
Bluetooth audio adds 150–300ms of latency by default, ruining competitive gaming. This tool forces SBC codec with low-latency mode for supported headsets, or switches to USB audio for zero latency.
Pros
Cons
Our Verdict
This one's free and built into Android — just hidden. Go to Developer Options → Bluetooth Audio Codec → switch to aptX LL or SBC at lowest subband for minimum latency. If your headset supports aptX Adaptive, that's even better.
Free (Pro: $2.99)
Before optimising, diagnose. PING runs continuous latency monitoring, packet loss detection, and jitter analysis — the three metrics that actually determine whether lag is your phone, your network, or the game server.
Pros
Cons
Our Verdict
Use this first before buying any gaming booster. If your ping is 8ms and packet loss is 0%, your network isn't the issue — look at thermals or background processes instead. If you're seeing 20%+ packet loss, no booster will fix that.
