# M's Counter vs Hemocytometer Sidekick

The clearest difference is rating: Hemocytometer Sidekick at 4.6 against M's Counter's 3.3. Hemocytometer Sidekick also leads on update cadence (every 2 months vs every 23 months) and ratings volume (29 vs 4). M's Counter's advantage is in-app purchases (none vs 5) and review sentiment (33% vs 0%). On price, ads and device support there is nothing between them.

Both are free to download. Hemocytometer Sidekick sells 5 one-off in-app purchases. M's Counter asks for nothing beyond the download.

Hemocytometer Sidekick holds the better App Store score, 4.6 against 3.3. That said, the two scores are not equally well evidenced: Hemocytometer Sidekick has 29 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 33% of M's Counter's written reviews are positive against 0% of Hemocytometer Sidekick's, so the app with the better star average is not the one people write more warmly about.

M's Counter ships an update every 23 months, Hemocytometer Sidekick every 2 months. The most recent releases landed on October 16, 2026 and October 7, 2026 respectively.
