ReceptionRating · Positive reviews · Number of ratings

National Grid holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 15K and 3.4K respectively. Written reviews complicate that: 25% of National Grid's written reviews are positive against 73% of Sunrun's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

National Grid ships an update every 6 weeks, Sunrun every 4 weeks. The most recent releases landed on November 5, 2026 and November 3, 2026 respectively.
