Verdict
The clearest difference is monetization model: Indigo at free against Plumb's | Standards's subscription. Indigo also leads on review sentiment (67% vs 56%) and iOS requirement (12.0 vs 15.1). Plumb's | Standards's advantage is rating (4.9 vs 4.5) and ratings volume (3.4K vs 15). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Plumb's | Standards holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Plumb's | Standards has 3.4K ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 67% of Indigo's written reviews are positive against 56% of Plumb's | Standards's, so the app with the better star average is not the one people write more warmly about.
Indigo ships an update every 2 months, Plumb's | Standards every 3 weeks. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
