Software that does one job, properly.

Photos carry GPS coordinates, device fingerprints and, for AI images, C2PA provenance labels. Posting a photo publishes all of it. MetaWipe exposes every field and strips it, entirely on-device.

• Inspect every field before removal, with GPS and AI labels flagged
• One-tap strip or per-group selection; always writes a new file, never overwrites
• Handles PDF and MP4/MOV video as well as images

Reef keepers test five to ten water parameters weekly, for years. ReefLog is that logbook: fast entry, trend charts with safe-range bands, maintenance reminders and dosing calculations.

• 7-day, 30-day, 90-day and annual charts per parameter
• Alkalinity, calcium and magnesium dosing against true tank volume
• CSV and PDF export, file-based backup

A perimenopause symptom diary that runs entirely on-device. A full day is logged in about ten seconds, and a short PDF can be exported for a clinician.

• Single-screen daily check-in across roughly 34 symptoms at three levels
• One-tap hot-flash counter with a home-screen widget
• PIN lock over an encrypted database

Carpenters enter a cut list and sheet dimensions; CutPlan nests the parts and prints a cutting diagram. It accounts for saw kerf, respects grain direction, and reports sheets required and waste percentage.

• 2D nesting with kerf, trim allowance and grain constraints
• Cut diagrams with numbered cut sequence, printable on A4
• Millimetres, centimetres or fractional inches

Knitters must track which row and which repeat they are on while both hands hold needles. RowMate is a layered counter: tap anywhere on the screen to increment, or use the volume keys.

• Top half increments, bottom half decrements — operable without looking
• Linked counters: completing a row cycle advances the repeat count automatically
• Keeps the screen awake, with haptic confirmation

Tabletop game masters track initiative, hit points and conditions for a dozen combatants simultaneously. BattleLedger replaces the scratch pad: ordered turns, one-tap damage, and encounter difficulty computed before play starts.

• Initiative, HP, temporary HP, death saves and 15 conditions
• 100-step undo — tables make mistakes, and mistakes should be reversible
• Bundled SRD 5.2 bestiary of 341 creatures, no connection required

A husbandry record for reptile keepers: feeding, sheds, weights, enclosure temperature and humidity in one place. The real purpose is catching a multi-week feeding refusal or weight decline early.

• One-tap feeding log: ate, refused or regurgitated
• Automatic refusal-streak counting with threshold alerts
• Pairings, clutches and species-specific incubation countdowns

Soap makers must calculate lye precisely; an error produces bars that burn skin. BatchBench combines the calculators, a per-batch record and a cost-per-bar model in one product.

• NaOH, KOH or dual-lye calculation with superfat
• Candle maths: vessel volume by fill ratio by fragrance load
• Batch records, FIFO inventory deduction, cure-date reminders

Every item in a home recorded with photo, purchase price, serial number and receipt, organised by room — so that after a fire, flood or burglary there is a list ready for the insurer rather than a memory exercise.

• Walk-through capture: shoot a whole room, name items afterwards
• Receipts and warranties attached per item, with 30-day expiry reminders
• PDF export formatted for insurance submission

A flock record for backyard keepers. Morning collection takes a few taps and the app charts yield automatically. The valuable part is converting feed spend into a true cost per dozen.

• Collection screen: one tap per egg, 50-step undo
• Cost per dozen, benchmarked against retail
• Species incubation schedules: chicken 21 days, duck 28, Muscovy 35, quail 17–18
