Pay once, keep it forever. Stone tells you exactly what to do: which weight to lift, the plates to load, when to rest, and when to add weight or deload. Log each set in a tap, then watch your strength climb over weeks and months. SWITCHING APPS? KEEP YOUR HISTORY Importing your existing lifting history is free, forever. Your past workouts and current weights come across in seconds, so you pick up exactly where you left off, no starting over. WHAT STONE DOES • Automatic progression – add weight when you succeed, deload after repeated misses, or set your own increment and deload rules • Programs your way – run 5x5, 3x5, 1x5, or 3x8, and tune the sets, reps, and weight jump for each lift • Plate calculator showing exactly what to load per side, in lb or kg • Guided warmup sets before your working weight • Rest timer between working sets • Swap any lift – substitutes inherit your weight, plate math, and PRs • Accessory work – add chin-ups, dips, or curls alongside your main lifts • History, progress, and PRs – weekly volume, streaks, and PR-aware charts • Make it yours – light or dark, four accent colors, alternate app icons, lb or kg YOU OWN YOUR DATA Your data lives on your device.

Cataract Surgery Guide is a patient education app designed to help people better understand cataracts, cataract surgery, lens implant choices, recovery, and common questions before and after surgery. The app explains cataract basics in simple language, including what a cataract is, how it affects vision, when surgery may be considered, what happens during surgery, and what patients can usually expect during recovery. Cataract Surgery Guide also includes an intraocular lens section to help patients learn about common lens implant options, including monofocal, toric, extended depth of focus, and multifocal lenses. A built in lens simulator helps show how different lens choices and astigmatism levels may affect vision in day and night settings. The app includes practical sections on pre operative care, post operative care, warning signs, eye drop reminders, and questions to ask about costs and expectations. It is designed to make cataract surgery feel less confusing and help patients have a better conversation with their eye surgeon. Features include: • Cataract education in clear patient friendly language • Surgery steps and recovery guidance • Lens implant education • Vision simulator for lens options and astigmatism • Eye drop reminder tool • Warning signs after surgery • Cost and expectation guidance • Available in English, Spanish, Chinese, Japanese, Korean, and Arabic • Adjustable text size for easier reading Cataract Surgery Guide is for education only and does not replace medical advice, diagnosis, or treatment from your ophthalmologist or health care professional.

Verdict
The clearest difference is in-app purchases: Cataract Surgery Guide at none against Stone's 1. Cataract Surgery Guide also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price and ads there is nothing between them.
