RateTier helps you check your current electricity rate in seconds. Choose a supported Canadian province, utility, and plan to see the current price, the next scheduled change, and today's rate schedule in one place. Track Ontario Time-of-Use (TOU) and Ultra-Low Overnight (ULO) pricing, or quickly reference supported flat residential rates across other provinces. RateTier works on iPhone, iPad, Home Screen widgets, Lock Screen widgets, Apple Watch, and Shortcuts, so your selected plan stays available wherever you glance. Set local alerts before upcoming rate changes, keep your rate context synced across app surfaces, and review the source and effective-date details behind the active rate pack. RateTier is privacy-first and offline-first. Core rate awareness works from bundled on-device data, with no account linking, no analytics, and no location permission required. RateTier is informational only and is not billing-authoritative. Always verify billing details with your utility's official terms and current communications.

Verdict
The clearest difference is in-app purchases: RateTier at none against CellMaster's 1. RateTier also leads on update cadence (every 9 days vs every 3 weeks) and device support (3 vs 1). On price, ads and iOS requirement there is nothing between them.
