All the features in this app and I cannot find that basic feature. It is probably there, but it is not easy to find ### 2/5 — A tool for tool buffs *2026-07-12, version 3.31.5* The complexity of the display and the myriad of features intrigued me. BUT in my day to day world … This app is pretty much useless. ### 5/5 — Don't get it!I *2026-07-06, version 3.31.5* I have the pro version that I bought longtime ago, but it does not use my offline Google or Apple maps. In order to used offline I have to subscribe which sucks since I already have the pro version! ### 5/5 — LOVE IT. INCREDIBLE TOOL! *2026-05-26, version 3.31.5* Absolutely invaluable. An absolute must-have for military. Fantastic for hunters as well. I am an officer in the National Guard and I use this app constantly in the field. Absolutely fantastic! ### 1/5 — Poor calibration on iPhone 17 *2026-03-29, version 3.31.5* The app when trying to calibrate on iPhone 17 is at least 25° off ### 1/5 — Original Supporters Backstabbed *2026-03-08, version 3.31.5* Apple should require developers to stick to lifetime agreements. Give new subscribers outings to choose options. Another example here of breaking the contract. ### 1/5 — Garbage *2026-02-24, version 3.31.5* Wants $ upfront, waste of time ### 1/5 — Bought this app then changes to monthly fee *2026-02-04, version 3.31.5* Screw this app developer, bought this app, then they decide to change to monthly fee based priced GFY ### 1/5 — Zu teuer *2026-01-14* Warum muss man Apps wöchentlich bezahlen? Kann das nicht monatlich oder jährlich eingeführt werden? Das wäre genauso, wenn man euch wöchentlich bezahlen würde, anstatt ein festes Einkommen. ### 5/5 — It's that good. *2026-01-04, version 3.31.5* I signed on to write a review and saw some raves from a boat captain and a pilot. I can't add anything to that but to say "yeah, it's that good." ## Frequently asked questions about Spyglass ### What does the Spyglass app do?
