Never forget which ink is in which pen. Inkcho is a fountain pen ink tracker built for collectors who rotate multiple pens and juggle too many bottles. Whatever the brand, see every pen's current ink at a glance. Log changes, track history, and never refill the wrong color again. 【What you can do】 ▷ See what's loaded at a glance Photo cards for every inked pen and its current ink, with pens due for cleaning first. ▷ Log ink changes & cleaning Record the date, ink name, and notes every time you refill or flush a pen. ▷ Pairing notes Rate pen × ink × paper combinations with text, star ratings (1–5), and swab photos. ▷ Detailed ink management Record sheen, shimmer, water resistance, drying time, feathering, and bottle level (5 stages).

Verdict
The clearest difference is update cadence: Inkcho at every 4 days against Keepop's every 10 days. Keepop's advantage is iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
