zLens

Crashes (on phone) every time I went into settings after five seconds each time. Really liked the watch interface. Probably would have been five stars just because of that.

It was the best lens app until it doesn’t have the option anymore to set a new back

Don’t have option to add a new pack anymore

This app is simple and does exactly what it's supposed to do. Other free lens tracking apps over-complicate things but this one is great. The only bad part about this app is that the advertisements are a little distracting, but it's outweighed by the fact that this app is free.

It's a grade app to keep track when to change your lenses

This app does why it says it does, but is useless for people who only wear their contacts on the weekends or occasionally. Would like to see a feature where the app would only track lens usage when you actually wore your lenses (rather than just counting the calendar days).

This app makes it easy to check when you changed your lenses and how soon you need to change them. It's helpful to record your prescription so you can see if it changes. Nice little app!

Was never able to use this as it kept crashing when I would try to enter a "new pack" (perhaps not iOS 7 compatible?) Will just use my calendar since the other contact lens reminder apps cost $$ which is bs...

Downloaded this app but wouldn't allow me to do anything ! Useless !
