Verdict
The clearest difference is ads: Slab Oracle at none against Midpoint's shown. Slab Oracle also leads on rating (5.0 vs 4.7). Midpoint's advantage is ratings volume (37 vs 6). On price, in-app purchases, monetization model 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. Slab Oracle sells 7 in-app purchases, starting at $3.99 per month and Midpoint sells 9 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Slab Oracle holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Midpoint has 37 ratings behind it against 6, so its average is the more settled of the two.
