Not even good

Forced me to pay for monthly after updating. The app is helpful I use it like 1-2 times per month. Not enough to force a subscription on users. Will just go back to using a spreadsheet like everyone else. Would have been happy to pay a 1 time fee but everyone wants to force you into subscriptions for minimal value apps

Pay to win

This was the best app in its time, back when it was a one time purchase. Now ever since the transition to subscription it constantly crashes, it locks you out. Can’t use on multiple devices because it says you have to pay. I bought the app for $12 and the first months they honored me and I could use the app without the subscription and nowadays not even that. I have to constantly write to support to let me access again the app

Hi, we would like to fix this. As we don't have your email address, can you please write to us at support@lifelearn.com so that we can help you better. We look forward to your email.

Can’t use it unless you pay $4 a month

Ended up deleting this app because what do you mean you placed it behind a pay wall now?! This app was so helpful and now completely useless.

Valuable recommended

The app saves significant time, reduces calculation errors, and improves workflow in a busy clinic setting. It also enhances communication within the team because everyone can quickly verify doses and calculations accurately.
Overall, this is a reliable, practical, and highly recommended app for veterinarians and veterinary nurses. It is a powerful support tool for emergency cases, anesthesia management, and daily clinical use
