SagittalMeter Pro vs Implant Identifier
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
SagittalMeter Pro
This app helps medical practitioners measure key parameters of sagittal balance directly from X-ray images using a phone. It aids in analyzing spine alignment for pre-operative planning and surgical outcomes. The tool provides measurements for pelvic incidence, pelvic tilt, sacral slope, and various lumbar and spinal angles.
- Measure sagittal balance parameters
- Analyze spine alignment
- Pre-operative planning tool
- Calculate pelvic incidence, tilt, and sacral slope
- Measure lumbar lordosis
- Advanced mode for comprehensive analysis

SagittalMeter is an educative app to easily measure sagittal balance parameters, by directly placing your phone on the sagittal X-Rays. The sagittal balance is an imperative factor to take into consideration for all practitioners treating spine problems and particularly for surgeons during the pre-operative phase. The compensatory mechanisms of a sagittal unbalanced spine may prevent a successful surgery outcome. A fundamental understanding of a correct sagittal alignment is strongly recommended in determining the correct use of fusion or non fusion devices. SagittalMeter enables you to measure 3 fundamental angles which are essential to analyze sagittal alignment (for pre, per and post-operative phases): • Pelvic incidence (PI) • Pelvic tilt (PT) • Sacral slope (SS) Values of lumbar lordosis are also important parameters to describe sagittal balance, so with SagittalMeter you can measure both: • L1-S1 lordosis • L4-S1 lordosis You can do a complete sagittal balance analysis by using advanced mode which extends the previous values with the following measures: • Occipito-C2 angle • Spino-sacral angle (SSA), angle between line from C7/T1 center to S1 plateau center and surface of S1 plateau • C7/T1 slope • C7-C2 angle • Spino-cranial angle (CIA), angle between line from C2 Dens to C7/T1 center and surface of C7/T1 endplate What does it mean? If a patient appears to have sagittal imbalance, this needs to be taken into consideration in the pre-operative planning. Any surgical treatment option should aim at the re-establishment of an ‘economic’ posture, achieved with the restoration of the patient specific sagittal balance. Remembering all theoretical normal values is very important but is definitively not easy and can even be impossible. SagittalMeter gives you the possibility to measure all the parameters in a quick way and gives you the average theoretical normal values for an equivalent asymptomatic healthy patient. How much correction do I need to restore a good balance in daily practice? Before any kind of lumbar fusion including the segment L4 to S1 it is mandatory to analyse the spine balance. If the PT or the lumbar lordosis are not correlated with the value of the PI, an approximation of the amount of correction requested can be evaluated with the FBI technique: C7 translation angle + Femur obliquity angle + PT compensation angle. SagittalMeter enables you to evaluate the FBI index value to get an average correction value.

Verdict
The clearest difference is price: Implant Identifier at Free against SagittalMeter Pro's $9.99. Implant Identifier also leads on rating (4.6 vs 3.0) and review sentiment (63% vs 33%). SagittalMeter Pro's advantage is iOS requirement (12.2 vs 15.5). On ads, in-app purchases and device support there is nothing between them.

Implant Identifier is free to download; SagittalMeter Pro costs $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Implant Identifier holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: Implant Identifier has 189 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 33% of SagittalMeter Pro's written reviews are positive against 63% of Implant Identifier's.
SagittalMeter Pro ships an update every 30 months, Implant Identifier every 3 weeks. Both last shipped on September 22, 2026.
