A long-established iOS app ($17.99 as of September 2026) that measures shot groups from a photo and keeps a shooter's diary. It has a small but very satisfied rating base — around 4.8 stars across a few hundred ratings.

Is TargetScan available on Android?

As of this writing we could find no Google Play listing for it — it lives on Apple's App Store. Zero Considerations is on both stores.

What does Zero Considerations do that TargetScan doesn't?

The steps after measurement: converting the group's offset into exact turret clicks for your specific optic, truing muzzle velocity from photographed drop, DOPE, a full ballistic solver, and 301 reticles drawn to scale — in one $9.99 one-time purchase.

TargetScan Alternative: What Happens After the Group Is Measured

TargetScan is one of the originals of photo shot-group measurement on iPhone — it's been on the App Store for over a decade, measures groups from a photo, keeps a shooting diary, and holds a small but very happy rating base (around 4.8 stars across a few hundred ratings, at $17.99, as of this writing). Respect where due: it proved this category before phones were good at it.

Who's writing this: the developer of Zero Considerations — one of the apps below. Weigh accordingly. Competitor facts are taken from their public store listings and sites as of September 2026, and where an app is the better pick for a job, the page says so.

Three practical differences

1. Platforms

TargetScan lives on the App Store; as of this writing we could find no Android listing. Zero Considerations is on both stores at $9.99 — relevant if your range buddies split between platforms, or you ever switch.

2. Price

$17.99 vs $9.99, both one-time. Neither runs a subscription — a thing worth honoring in both directions in this category.

3. What happens after the measurement

This is the real fork. A measured group is an answer to "how did I shoot?" Zero Considerations treats it as the input to "what do I dial?":

Exact turret clicks for your optic's click value and direction, from the measured offset — dial, then confirm with a group.
Truing — muzzle velocity backed out from photographed drop at a known distance.
Full solver and DOPE — drop, wind, energy in MOA, MIL, or clicks.
301 to-scale reticles — see your holdovers on your actual reticle.
Scale from coded markers — the free printable targets carry coded corner markers that set the photo's true scale and correct camera tilt/perspective before anything is measured.

TargetScan entries reflect its public App Store listing as of September 2026. If you own it and it does what you need, that's a fine place to be — this page is for shooters deciding fresh, or wanting the steps after measurement in the same app.

For education and lawful sporting use. Figures here are rough and load-dependent — treat them as orientation, not dope. Always confirm your zero with live fire at your real distance before relying on it, and follow all firearm safety rules and your range's procedures.

Zero Considerations — photograph the target, get the measured group and the exact clicks to dial, then keep the DOPE. One-time $9.99 on both stores — no subscription, no account, works with no signal.
