With Laboratory values Pro, you can quickly and easily find out about blood laboratory values. This laboratory app gives physicians and non-medical professionals a generally understandable, quickly navigable and clearly structured overview of the most important routine laboratory parameters and possible causes of their increase and decrease. The laboratory values can be found alphabetically in menu item A-Z as well as under the respective categories. The standard values are given in both the old units and SI units. The content presented here is for neutral information and general education only and in no case replaced personal consultation, examination or diagnosis by a licensed physician. No medical decision may only be based on results and information of this program - Laboratory Values Pro App. We point out that neither remote diagnosis nor therapy suggestions are made for the individual case. For each laboratory value a short information can be queried quickly. The individual brief information is formulated in a generally understandable way and provides an overview of the indication, function and task of the respective laboratory value. For each laboratory value numerous possible causes of their increase and decrease will be indicated. Laboratory Pro gives the user an overview of the most important routine laboratory parameters including hematology, differential blood counts, clinical chemistry, blood clotting, Quick, INR, electrolyte balance, tumor markers and blood gas analysis. In addition to classic scrolling, the program enables quick navigation between laboratory name, abbreviation of laboratory value, standard value, differential diagnostic interpretation of increase and decrease in value (especially for physicians, medical students, interested lay people). An additional search bar allows the targeted search for the desired laboratory value.

Eye Charts is a vision testing app independently proven most accurate in a peer-reviewed study (JAMA Ophthalmology). Trusted by parents and clinicians to check, record, and track children's vision since 2018. Early detection of myopia allows you to take preventive action, seek medical advice promptly, and prevent pseudomyopia from worsening into myopia or stop nearsightedness from deteriorating further. INDEPENDENTLY EVALUATED ACCURACY Eye Charts was previously published as Visual Acuity Charts and was independently evaluated in a peer-reviewed study published in JAMA Ophthalmology (https://pmc.ncbi.nlm.nih.gov/articles/PMC7809609/). MORE THAN A DIGITAL EYE CHART Unlike paper charts that can fade, warp, or become memorized, Eye Charts presents randomized optotypes for each test. This helps reduce variability when repeating measurements over time. Choose from: • Snellen • ETDRS • Landolt C • Tumbling E • HOTV • Numbers • Shapes Charts use LogMAR-based sizing and support multiple visual acuity notations, including: • Fraction • LogMAR • MAR • Decimal • VAS FLEXIBLE TESTING Test at different distances to suit small rooms, hallways, clinics, schools, or other available spaces. Eye Charts is self-illuminated on iPhone and iPad, so chart visibility is less dependent on ambient room lighting. Screen brightness can be adjusted, including for longer testing distances such as 6 metres. THREE WAYS TO TEST 1. Doctor and patient — in a clinic or at home 2. Self-test with a mirror — wear an eye patch; the effective testing distance is doubled 3. Self-test with a Bluetooth keyboard — from a few meters away SEE TRENDS, NOT JUST SNAPSHOTS Record test results for individual subjects and visualize changes over time with simple graphs. This makes it easier to notice: • Gradual changes in visual acuity • Stability following an intervention • Differences between visits or repeated tests For parents, this provides a convenient way to monitor a child's visual acuity over time. For healthcare professionals, it provides a practical record for routine screening and follow-up. IMPORTANT MEDICAL NOTICE Eye Charts is a visual acuity screening and measurement tool. It does not replace an examination by an optometrist or ophthalmologist. It does not diagnose eye conditions such as strabismus, esotropia, exotropia, hyperopia, or astigmatism. Regular professional eye examinations are recommended, and you should seek professional medical advice if you notice changes in vision.

Verdict
The clearest difference is review sentiment: Eye Charts at 68% against Lab Values Pro's 0%. Eye Charts also leads on update cadence (every 2 months vs every 10 months) and ratings volume (29 vs 3). Lab Values Pro's advantage is rating (4.0 vs 3.5) and price ($0.99 vs $4.99). On ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Lab Values Pro costs $0.99 and Eye Charts $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Lab Values Pro holds the better App Store score, 4.0 against 3.5. That said, the two scores are not equally well evidenced: Eye Charts has 29 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 0% of Lab Values Pro's written reviews are positive against 68% of Eye Charts's, so the app with the better star average is not the one people write more warmly about.
Lab Values Pro ships an update every 10 months, Eye Charts every 2 months. The most recent releases landed on October 6, 2026 and October 18, 2026 respectively.
