## What is Hemocytometer Sidekick?

Make cell counting with a hemocytometer effortless!

You know the drill--time to count cells for your experiment. Get out the hemocytometer and squeaky mechanical counter, prepare your dilution, fill the chamber, then look under the scope and start pushing the lever. Get to the end of a square, write down the count, reset the counter, and repeat. Finally, try to remember the right calculation, then write down the result.

What if you didn't need the squeaky counter? The scrap paper? A manual calculator?

Sure, you *could* get an expensive, fancy cell counter with wasteful disposables. But why do that when a $5 app is nearly as good?

Hemocytometer Sidekick eliminates those annoyances. Record one or two counters for all samples with automatic calculations (including viability, blood counter), and use the full grid or the center square. Data is saved for you, so you can record it in your notebook at your convenience.

Hemocytometer Sidekick, designed from the ground up by a biologist, will make your life in the lab so much easier, that I'm giving you 10 measurements for free!

### 1/5 — “Free”

*2023-07-06*

Pretty scammy to list an app as Free only for it to have zero functionality unless an in app purchase is made. I’m pretty sure this is against the App Store terms of service. Why not just list it for $5 …

### 1/5 — It’s making me pay more money for updates

*2023-05-12*

I don’t need any updates and I already paid for the app. Now I can’t access the Home Screen. What the heck?

**Developer response:** Hi, sorry for the issue. And for just seeing this review. You didn't have to buy anything. I understand why it appeared as such to you though. Apple changed something so that the menu button wasn't visible anymore on newer devices that I didn't have available to test. It was still there and would have worked. Unfortunately it took me some time to find out this was occurring, but it has since been fixed. Please use Apple's process for refunds.

### 3/5 — Nearly there

*2018-10-18*

App works well, biggest drawback is not having Audible sounds on counters. When you head is in the microscope having two seperate sound for the viability mode would make this a 5 star
