### 4/5 — Amazing, but needs to support iCloud

*2024-08-03, version 2.2*

I love this app! Best way to read/store TLC plate info, but I do wish it supported iCloud so info could be easily transferred from phone to MacBook to print and then into the lab notebook…

### 5/5 — Little gem

*2015-06-25*

Great app for daily use. Would have been better if I can enter solvent system easier, for example customisable presets

### 4/5 — good app

*2015-06-24, version 1.2*

The automatic spot detector function isn't that great, but it has an option to manually drag markers to spots. Still beats using a ruler to find Rf's.
