Point your camera at anything you need to count — coins, pills, bricks, pipes, parts, boxes, even a crowd — and get an instant total without tallying by hand. Count This runs a real on-device detector: snap or import a photo, and it finds every matching item in the frame automatically. Then you fine-tune by hand — tap to add anything it missed, tap to remove any extra — so the final number is always exactly right. No cloud, no waiting, no clicker in your pocket. WHAT YOU GET - An accurate total in seconds instead of counting one by one - Automatic detection that separates tightly packed, high-contrast items - Tap-to-add and tap-to-remove so every count is perfect, not just close - Color categories to tally different item types in the same photo at once - A saved library of every count with photo, markers, and running totals - Clean PDF and JPEG exports to share, file, or hand off as proof PERFECT FOR - Warehouse and inventory staff counting stock, cartons, and pallets - Contractors and trades tallying pipes, rebar, bricks, and fixings - Lab, pharmacy, and clinic work counting pills, samples, and vials - Anyone tired of losing their place counting by hand WHY NOT JUST USE A CLICKER OR COUNT BY HAND? A tally clicker gives you a number but no proof and no record — lose your place once and you start over. Count This keeps the photo, marks every item it counted, and lets you correct it, so you get an auditable result you can save and re-open later. PRIVACY All detection runs on your device. Your photos and counts stay on your iPhone — nothing is uploaded to any server. FULL ACCESS Count as often as you like and save a few results every day for free. Upgrade to Pro for unlimited saved counts, unlimited categories per photo, and PDF/JPEG export: - Weekly plan - Yearly plan - Lifetime — one-time purchase, unlocked for good Snap a photo and let your camera do the counting.

Verdict

The call

The clearest difference is in-app purchases: Construction Calculator at none against Object Counter's 3. Construction Calculator also leads on device support (3 vs 1) and iOS requirement (15.0 vs 26.0). Object Counter's advantage is ads (none vs shown). On price there is nothing between them.
