Verdict
The clearest difference is rating: Simple Notes at 4.0 against SlipBox's 3.3. Simple Notes also leads on ratings volume (39 vs 3) and device support (4 vs 2). SlipBox's advantage is update cadence (every 3 weeks vs every 2 months) and chart position (#188 vs unranked). On review sentiment, ads, in-app purchases and monetization model 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
Simple Notes costs $2.99 and SlipBox $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Simple Notes holds the better App Store score, 4.0 against 3.3. That said, the two scores are not equally well evidenced: Simple Notes has 39 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 82% of Simple Notes's written reviews are positive against 88% of SlipBox's, so the app with the better star average is not the one people write more warmly about.
Simple Notes ships an update every 2 months, SlipBox every 3 weeks. The most recent releases landed on September 21, 2026 and September 19, 2026 respectively.
